Is recycling worth it?

Last year my family took part in a trash cleanup group with some of my neighbors, but it was only recently that I sorted the recyclables that we had picked up. As I pried caps and labels off plastic bottles and shook dirt out of aluminum cans, I began to wonder about the items’ eventual fate. For my last article, I had researched the United States’ problematic practice of shipping recyclables to other countries. I wondered if the items I was sorting would be converted into new bottles and cans or if they would end up cluttering a dump in another country.
Recycling single-use packaging makes sense since the packaging has caused problems worldwide. The increase in single-use items after World War II (Park) led to a myriad of landfills and islands of plastic trash in the ocean. Garbage in landfills takes an estimated 500 years to decompose, and the plastic in them leaches toxic chemicals into the ground (“The Truth About Bioplastics”). As a result, recycling seems better for the environment. However, it is not the best possible option. I wanted to list downfalls of recycling that would be better solved by reducing and reusing waste.
Problem #1: Recycling can create pollution in other countries.

In my last article, I talked about China’s National Sword Policy, which took effect in 2018. The policy banned most recyclables from entering China, only allowing imports of ones with low rates of contamination. As a result, the United States has begun shipping recyclables to many other countries, including Ghana, Cambodia, and Bangladesh. An estimated 20% to 70% of it is thrown away since it is contaminated and thus unusable for recycling. Every year, the United States ships about 1 million metric tons of plastic waste overseas. The waste is harmful for the countries that accept it. For instance, in Southeast Asia, American plastic waste is linked to contaminated water, crop death, respiratory diseases, and organized crime (“Recycling in the U.S. Is Broken”).
In order to learn more about plastic recycling in developing countries, CBC Canada reporters pretended to be plastics brokers in Malaysia (“Tracking Your Trash” 00:00:45-00:00:52). They found that most recycling workers are payed little and labor in dangerous conditions (“Tracking Your Trash” 00:01:10-00:01:25). The reporters also found that Malaysia has many illegal recycling businesses that import huge amounts of plastic (“Tracking Your Trash” 00:01:25-00:01:40), while the country itself is trying to curb the influx of recyclables (“Tracking Your Trash” 00:04:15-00:04:27). They walked over hills of Canadian and American plastic bags at the plant of an illegal recycler that had been shut down. Now the plastic sat there, polluting the land (“Tracking Your Trash” 00:02:15-00:03:21). Malaysia’s environment minister had recently shut down 150 illegal recyclers (“Tracking Your Trash” 00:04:30-00:04:45). because they had been dumping and burning huge amounts of contaminated materials. Burning plastic constantly filled the air with smoke and fumes and killed its pristine forest (“Tracking Your Trash” 00:06:10-00:07:35). One woman that the reporters interviewed was concerned that her young son was becoming sick from the awful air (“Tracking Your Trash 00:08:00-00:08:42). Nearby, the reporters found tiny plastic pellets being ejected downriver from a recycling plant. Many people in a nearby town fished and farmed with the river’s water, which explained why some of them were becoming ill (“Tracking Your Trash” 00:09:40-00:11:00). According to one Malaysian activist, she was protesting the situation because she did not want her country to become an “international rubbish bin” (“Tracking Your Trash” 00:10:10-00:10:19).
Problem #2: There is little demand for recycled material.
Before China’s National Sword Policy, American communities were able to sell their recyclables to Chinese companies for money, but after the policy took effect, the communities have had to pay to have their recyclables removed. For instance, Bakersfield, California used to earn $65 for each ton of recyclables they sold, but now they have to pay $25 for each ton to be removed. Franklin, New Hampshire used to make $6 a ton selling recyclables. Now, residents can either pay $125 per ton to have them recycled or $68 per ton to have the same materials incinerated. The United States has no federal recycling program, so the National Sword Policy was dealt with differently by each of the 20,000 communities across the country that provide their residents with recycling services (“Recycling in the U.S. Is Broken”).
Problem #3: Most materials cannot be recycled infinitely.
Paper can be recycled between five and seven times, while plastics are usually recycled once or twice. In fact, only plastic No. 1 (PET) and plastic No. 2 (HDPE) are frequently recycled. Plastics with resin codes 3 through 7 are rarely recycled (“Recycling in the U.S. Is Broken”). Metals and glass are exceptions since they can usually be recycled infinitely.
Problem #4: Many plastic recyclables are not recycled.

A set of labeled recycling bins. Part of the Wikipedia article “PET bottle recycling”. Courtesy of Wikipedia and its creating user Terence Ong. The recovery rate of plastics is poor. In 2015, Canadians recycled 79% of PET bottles and jars, but only recycled 11% of PET fruit holders and other clamshell containers (Chung). Overall, only 9% of Canadian plastic was recycled (“Tracking Your Trash” 00:17:00-00:17:15). Americans tried to recycle 29% of their plastic bottles in 2017 (Chung), but some of the bottles were contaminated, so ultimately only 21% of them were recycled (“Recycling in the U.S. Is Broken”). Six times more American plastic is incinerated than recycled. The main reason why plastic recycling is rare is that virgin plastic is cheaper than recycled plastic, so economically it makes more sense to produce new plastic (“Recycling in the U.S. Is Broken”). The low cost of virgin plastic is one of the main reasons why recycling is failing.
Problem #5: Some “recycling” companies are not required to recycle their plastic.
In British Columbia, Canada, reporters installed tracking devices on bales of plastic that were brought to different recycling companies (“Tracking Your Trash” 00:11:00-00:12:13). All three bales stayed in British Columbia, but out of three companies, only Merlin Plastics actually recycled the materials they were given (“Tracking Your Trash” 00:13:55-00:14:17). A company named GFL burned the plastic in an energy facility and took the remaining toxic ash to a landfill (“Tracking Your Trash” 00:14:18-00:15:17), while a company named Waste Connections brought the material directly to a landfill (“Tracking Your Trash” 00:15:18-00:16:16”). It turns out that supposed “recycling companies” in Canada are under no legal obligation to recycle the materials that they are given (“Tracking Your Trash” 00:16:16-00:16:35).
Problem #6: Recycling creates its own waste.
Whenever something is recycled, it goes through a chemical process that creates toxic waste. As a result, reducing and reusing are much better options than recycling (“Tracking Your Trash” 00:12:45-00:13:27). Unfortunately, whenever a government tries to ban a plastic item, both plastic producers and recyclers protest the ban, making it difficult to solve the problem (“Tracking Your Trash” 00:17:15-00:19:48).
Problem #7: Psychologically, having a recycling option can cause people to produce more waste.
A study published by Harvard Business Review showed that people use more cups and gift wrap when there is a recycling bin available. That shows that people count on recycling as an effective solution to harmlessly deal with their waste, which it is not (Dell).
How Recycling Works In One State

Workers sorting single-stream recycling in a Materials Recovery Facility at the Shady Grove Transfer Station in Montgomery County, Maryland. Part of the Wikipedia article “Recycling”. Courtesy of Wikipedia and the USEPA Environmental Protection Agency. As a case study, I researched the recycling process in my home state of Massachusetts. Massachusetts has nine MRFs, or Material Recovery Facilities, which sort 638,000 tons of materials each year. Recyclables travel through a maze of manual and mechanical sorters, including high-tech equipment like the near-infrared technology that identifies different plastic resin types at the Springfield MRF. Once materials are sorted, the recyclables are crushed into thousand pound bales and sold to companies (“The Truth About Plastics Recycling”). Most paper and cardboard from western Massachusetts are sold to a buyer in eastern Massachusetts (Kaplan). Some plastics are sold to Unifi, a company whose recycling plant is in North Carolina (“The Truth About Plastics Recycling”). Unifi uses the plastic to make fiber, so they turn plastic bottles into carpets, athletic clothing, and elastic straps for masks (“Repreve”). It’s encouraging that Massachusetts has a well designed recycling program. However, it would be better for its residents to reduce their plastic usage.
A Typical PET Recycling Process
Step 1: PET items are collected in recycling facilities, or MRFs.
Step 2: The items are separated from other materials in the MRFs.
Step 3: The objects are squeezed into small bales and transported to a different facility.
Step 4: The bales of plastic are processed by being separated into color streams and ground up into small flakes.
Step 5: The flakes are washed to remove lids, rings, labels, and glue.
Step 6: After being washed, the flakes are heated to decontaminate them of post consumer substances and flavors.
Step 7: The plastic flakes are melted, and solid contaminants are strained out using a melt filter. In some places, this step happens before step 5.
Step 8: The molten plastic is cooled and converted into spherical, crystallized PET pellets.
Step 9: The plastic pellets are melted again and made into preforms. The preforms are then sent to manufacturers who make them into different bottle designs.
If PET plastic is not pure enough to be made into bottles again, it will be melted, stretched into fiber, and spun to make polyester yarn, which is found in everything from winter coats to roofing insulation (“How does PET plastic recycling work?”).Infinitely Recyclable Plastic: A solution to the world’s plastic problems?
Recently, a team of researchers at Lawrence Berkeley National Laboratory developed a new type of plastic which can be recycled infinitely without a reduction in its quality. The new plastic is called PDK. In order to understand why PDK is so recyclable, its helpful to provide some background information about plastics. Plastic resins are made of many individual molecules called monomers bound together to form long chains called polymers. In order to give textures, colors, and other properties to plastics, their resins are mixed with additives, including pigments, heat stabilizers, and flame retardants. In normal plastic recycling, plastics with different additives are melted down together. The additives mix poorly, contaminate the resin, and give the recycled plastic a lower quality. PDK, however, is different from traditional plastics in that its polymers easily break down into monomers when mixed with an acid. As a result, its easy to separate the plastic molecules from additives and use them to make new plastic (Kovner).
PDK looks fairly promising, and manufacturers are already interested in buying it. PDK would save money for industries that are given back their products at the end of their lifespan, such as automobile and electronics businesses. It could also potentially be used for packaging. While PDK is currently produced with chemical processes, it could eventually be produced using microbes (Kovner).
Infinitely recyclable plastics will be helpful, but they are not a solution to the world’s burgeoning plastic problem. While PDK is useful for longterm products like cars and electronics, single-use PDK packaging would cause as many problems as other single-use plastics since not everyone would be responsible enough to recycle it. In addition, the acids used to recycle PDKs and the plastic additives removed during the recycling process could become their own toxic waste. PDKs are a promising development for recycling, but they are not a panacea for the plastics problem.
Can compostable and biodegradable plastics be recycled?
No, compostable and biodegradable plastics usually cannot be recycled. Similar to bioplastics, they can contaminate the recycling process, creating more waste. To avoid contamination, be careful to only recycle items that are accepted in your town. Compostable plastics can be composted in either home compost or an industrial composting facility. It is much easier for plastics to decompose in a professional compost facility since those facilities have controlled conditions. As a result, only put materials marked “home compostable” in a home compost pile. Similar to transfer stations and recycling pickup services, professional composting services may only accept certain items. Be careful to only give them compostable plastics that they accept. Its more difficult to figure out what to do with biodegradable plastics. If a plastic is labeled “biodegradable”, that means that it was able to break down into natural substances in controlled conditions in a lab. However, it’s unclear what the controlled conditions were, so the plastic may not be compostable. Some professional composting facilities accept biodegradable plastics, but its important to check with the facility (“Is biodegradable and compostable plastic good for the environment?”).
Greenwashing
Greenwashing is when companies use deceptive marketing to appear more environmentally friendly than they actually are. For instance, Coca-Cola has been advertising its PlantBottle, a plastic bottle made from 30% sugarcane and 70% petroleum. The bottle is not biodegradable and is very much like traditional petroleum bottles (Robbins). In fact, items made of hybrid plastic were found to be the worst for the environment in a 2010 University of Pittsburgh study (“The Truth About Bioplastics”). However, that does not stop Coca-Cola from promoting how the PlantBottle can help “find a solution to our planet’s packaging problem” (“FAQ: What is PlantBottle packaging?”).
Another famous example of greenwashing is the Keep America Beautiful campaign, which originally encouraged people to pick up litter. However, it was founded by large packaging businesses like the American Can Company and the Owens-Illinois Glass Company. While the organization claims to be against littering, in reality, its members have lobbied against single-use bottle bans and bills requiring packaging to be returnable or recyclable instead of disposable (Park). If those bills had been passed instead of shut down, they could have reduced the American garbage crisis.
Common greenwashing tactics include putting all the blame on consumers for environmental problems, marketing products as environmental when they actually aren’t, and pretending to be more sustainable than they are so governments don’t regulate them (Park). It is difficult to tell the difference between greenwashing and genuinely environmental products. Greenwashed products are labeled with popular, vague terms like “plant-based”, “bio-based”, and “sustainable”, while products that are actually produced ethically are likely certified by third parties (Robbins). If you want more tips on how to recognize greenwashing, read this article: www.ctsbcouncil.org/types-of-greenwashing/.Is recycling worth it?
Recycling is helpful since it is a way to reuse materials so that they aren’t wasted. I will keep recycling in the hopes that the items I am bringing to the transfer station will be turned into fiber, new cans, and other useful products. However, recycling is not the solution to the world’s waste problem. Reducing and reusing are much better options.
In my view, the best solution would be for everything to be reusable. Imagine if people could buy bread from the store in a reusable bag. They put the reusable bread bag in a reusable shopping bag and take the bread home. After a person is done with her bread, she can bring the bread bag back to the store, where it is washed and used to store more bread. Stores could receive their products in bulk shipping containers that are used for multiple shipments. While my idea sounds far fetched, glass soda bottles were reused through a similar cycle in the 1970s. After a number of plastic bag bans in Canada, stores are already developing systems for customers to return reusable bags (Harris). Those systems could be replicated for other packaging.
In the future, innovations will further reduce the world’s waste problem. Infinitely recyclable plastics will be helpful for car parts and medical applications. Compostable bioplastics could come in handy as single-use takeout containers. However, steering clear of plastics is probably a better solution. Glass and metal are both plastic alternatives that can be recycled infinitely. Aluminum recycling is more successful than plastic recycling since recycling aluminum is cheaper than mining (Husband) and prevents the environmental degradation mining causes (“Aluminum Recycling”). Paper is also better because it is biodegradable. In addition, a number of new plastic alternatives are being produced by different companies. The Japanese design company AMAM makes packaging from the agar in red marine algae. Meanwhile, the United States Department of Agriculture developed a biodegradable and edible film from the milk protein casein. The film is 500 times better at keeping food fresh than plastic. Finally, the New York based company Ecovative uses mycelium to make a variety of objects. Mycelium, which is similar to mushroom roots, can be made into biodegradable packaging material, planters (“The Truth About Bioplastics”), vegan leather, and even a chair (Ecovative). All of those alternatives are made from organic substances and thus are easily biodegradable in nature.
Legislation
Legislation banning various plastic items is more helpful than recycling. A number of places have banned plastic bags, which has greatly reduced plastic bag litter. Austin, Texas experienced a 90% reduction in plastic bag litter in the first six months of its bag ban. Unfortunately, the ban was later nullified by the Texas Supreme Court. San Jose, California’s ban cut plastic bag litter by 89% in storm drains, 60% in creeks and rivers, and 59% in city streets. Washington, D.C. also experienced a drop in litter when 30% less bags were collected in cleanups. Free water bottle refill stations and bottle deposit laws have effectively reduced litter as well (Dell). Currently, the Massachusetts legislature is reviewing bills to phase out single-use plastics, and I am eagerly awaiting their decision.

The Zero Waste Lifestyle

Hi everyone! I wanted to write an article about the zero-waste lifestyle since I’ve been interested in it for a long time. Simply defined, the zero-waste lifestyle requires producing minimal waste. I wanted to share the reasoning behind the lifestyle and practical ways that people can accomplish it.
Reason #1: The world is running out of space for its garbage.

The EPA’s waste management hierarchy. Part of the article “National Overview: Facts and Figures on Materials, Wastes, and Recycling” on the website epa.gov. Courtesy of the EPA. The main reason to practice a zero-waste lifestyle is to reduce the world’s garbage. In the United States alone, the average person throws away at least 1,609 pounds of trash per year. This nation only has 5% of the world’s population, but discards 40% of its waste (Acimovic). According to one statistic, the United States and Canada are the two highest per capita generators of municipal solid waste in the world, with 2.58 kg (5.7 lbs) and 2.33 kg (5.1 lbs) of garbage generated per person per day respectively (Tiseo). The United States’s garbage has almost doubled since 1960. It grew from roughly 2.68 pounds per person per day in 1960 to 4.9 pounds per person per day in 2018. Fortunately, more trash is being recycled, composted, and combusted for energy (“National Overview”).
The focus of the zero-waste lifestyle is reducing municipal solid waste. The EPA defines municipal solid waste as “various items consumers throw away after they are used”. It includes plastic bags, tires, old clothing, and computers, but doesn’t include construction and demolition debris and municipal wastewater sludge. In the United States, the total generation of municipal solid waste was 292.4 million tons in 2018. Out of that amount, 69 million tons were recycled, 25 million tons were composted, 35 million tons were combusted for energy recovery, 146 million tons were landfilled, and 17.7 million tons were dealt with by other methods (“National Overview”).

This chart shows the amounts percentages of America’s garbage that are recycled, composted, combusted for energy recovery, landfilled, and disposed using other methods. Not all developed countries manage their trash in the same way as the United States. Sweden, for instance, only dumps 1% of its trash in landfills. Instead, Swedes recycle 47% of it and burn 52% to create energy. The energy heats 1 million homes and provides electricity to 250,000 homes. In order to encourage its citizens to recycle, the Swedish government has built recycling centers within a thousand feet of every residential area and gives discount vouchers to citizens who use recycling machines (Acimovic).

Reason #2: Plastic in the ocean
One of the best indicators of the worldwide garbage crisis is the amount of plastic that ends up in the ocean. That plastic harms marine life and pollutes sea food with dangerous chemicals. In 2020, 126.5 million kg (about 279 million lbs) of plastic waste from India ended up in the ocean, making the country the ocean’s leading plastic polluter. That much plastic would weigh the same as 250 thousand bottlenose dolphins. The United States produces about 42 billion kg of plastic waste annually, which is double the amount that India produces. However, only 2.4 million kg of American plastic waste ends up in the ocean. At first glance, that makes America look eco-friendly. The hidden reality, however, is that America exports much of its plastic waste, especially to countries with poor waste management systems. In fact, 12% of America’s exported plastic waste went to India in 2018. Plastic waste from America may end up in the ocean off of other countries (Melville).
The Ocean’s Top 10 Plastic Polluters
Country Amount of Plastic Waste in the Ocean 1 India 126.5 million kg 2 China 70.7 million kg 3 Indonesia 56.3 million kg 4 Brazil 38 million kg 5 Thailand 22.8 million kg 6 Mexico 3.5 million kg 7 Egypt 2.5 million kg 8 United States 2.4 million kg 9 Japan 1.8 million kg 10 United Kingdom 703 thousand kg (Melville)
Reason #3: Waste disposal strains relationships between countries
Although recycling plastic is helpful, it is difficult to find buyers for the plastic. Roughly one-third of American recyclables are shipped overseas, so the industry depends on a global market. Unfortunately, the market for recyclables was greatly reduced in 2018 when China no longer accepted them. Prior to China’s ban, the United States had exported roughly one-sixth of its recyclables to that country. For decades, China had recycled the world’s garbage to fuel its manufacturing boom. However, the large amounts of trash soon became a danger for China’s people and its environment. In a statement the Chinese government released to explain their ban, they described shipments of recyclable materials contained nonrecyclables that were “dirty” and “hazardous” (Profita). At least 30% of the materials sent to China were contaminated by nonrecyclables, so they were thrown away in landfills. Some likely even ended up in the ocean (Cho). All things considered, China’s ban on accepting recyclables is understandable.
After the ban took effect, the United States began to ship to Vietnam, Malaysia, and Thailand, but soon those countries closed their borders as well. Currently, the United States ships recyclables to Cambodia, Bangladesh, and Ghana since those countries have lax environmental laws and cheap labor (Fernandez). Unfortunately, the fact that our nation sends huge amounts of trash and recycling abroad strains its international relations and unfairly harms the citizens of poorer countries.
What is the solution to these problems?
I believe a zero-waste lifestyle is the best solution to plastic pollution. A zero-waste lifestyle involves boycotting trash by only using reusable items. If a person buys a single-use item, it should be either compostable or recyclable. Inspiring examples of people living zero-waste include those who collect only one jar full of trash each year. Unfortunately, boycotting waste is much easier said than done. Some zero-waste practices include drinking out of reusable mugs at coffee shops, buying secondhand furniture and clothing, bringing reusable bags to stores, and creating DIY cleaners and personal care items (Jakob). Here is a list of zero-waste tips that we can implement.
21 Zero-Waste Tips

Some zero waste items, including a reusable water bottle, cutlery, mason jars, a spice jar, and a reusable grocery bag. Part of the article “Zero waste” on Wikipedia. Courtesy of Wikipedia and its creating user Hannahdobrott. - Drink out of a reusable water bottle and use reusable food containers. This could include mugs and Pyrexes for ordering out.
- Buy loose vegetables and fruits and carry them in a cloth bag.
- Compost food scraps.
- Buy secondhand items. Many household items, like furniture and clothing, can be found secondhand at thriftstores or through neighborhood Facebook groups.
- Replace paper towels with reusable clothes and napkins.
- Try shampoo and conditioner bars.
- Pack your own lunch instead of buying lunch.
- Donate items that you no longer use.
- Research zero waste personal products. There are many compostable and zero-waste products out there, and there are also many DIY recipes for items like deodorant, toothpaste, mouthwash, shampoo, and face masks.
- Borrow books from the library. If you buy books, buy e-books or secondhand books instead of new paper books.
- Recycle whatever can be recycled in your area.
- Don’t buy items that you don’t need. For instance, don’t worry about buying the latest clothing or electronics.
- Make your own food instead of buying processed food. While it may be time consuming, people can make their own hummus, breads, crackers, cookies, and other normally processed food items. Making food in large batches and freezing it may be a good idea.
- Grow your own vegetables. I’m trying to grow tomatoes and basil in pots this year, which I’m excited about.
- Eat less meat and more local produce.
- Make DIY cleaners and detergents. Cleaners can easily be made out of citrus peals.
- Buy from farmer’s markets, shops selling local food, and zero-waste stores. Many zero-waste stores have food in dispensers instead of bags.
- Give experience gifts instead of physical gifts. For instance, give a friend a gift card to a restaurant or movie theater in lieu of a physical item.
- Avoid buying balloons and other needless plastic items. You could probably find compostable or reusable decorations instead.
- Use a reusable shaving razor and reusable q-tips.
- Take school notes on the computer instead of paper notes. I’ve personally started writing outlines for my blog articles online instead of writing on paper to organize my information.
The tips above are either ones I’ve tried personally or that I’m interested in trying. Most of my ideas are from the article “90 Zero Waste Tips For Beginners” written by Merilin Vrachovska on the blog Almost Zero Waste. Here’s a link to the article if you want more ideas: www.almostzerowaste.com/simple-zero-waste-tips/.
Shampoo and Toothpastes: Zero-Waste DIY Products
Sometimes, people make their own products in order to find a zero-waste version. A zero-waste lifestyle involves coming up with innovative solutions for common problems. For instance, people with curly, thick, dry hair may not need any shampoo and can simply wash their hair with water. Others might be able to forgo shampoo by washing with a baking soda paste (Bennett). DIY toothpastes are helpful as well. Toothpaste tubes are often impossible to recycle since they are made up of fused plastic and aluminum. In addition, commercial toothpastes often contain the detergent sodium lauryl sulfate and the antimicrobial agent triclosan. Sodium lauryl sulfate is concerning since it is a potentially unsafe chemical that was originally patented as a pesticide. Triclosan, on the other hand, can cause a number of problems ranging from making bacteria resistant to antibiotics to poisoning aquatic ecosystems. In order to deal with those problems, many people purchase or make their own zero-waste toothpastes and tooth powders (Binford). Some dentists don’t recommend DIY toothpastes since they don’t contain fluoride, a mineral that strengthens teeth. However, others recommend DIY recipes made of coconut oil and baking soda. Coconut oil kills cavity-causing bacteria and boosts good bacteria in the mouth (Didonato, Burhenne), while baking soda is an alkaline that neutralizes acid in the mouth (Didonato). Dentists that recommend DIY toothpaste suggest making sure that you have fluoride from other sources, such as from your water supply (Didonato, Burhenne). Personally, I’ve experimented with a simple toothpaste recipe that involved mixing 1 tablespoon of coconut oil with ½ tablespoon of baking soda (Binford). I’ve tried it out for the past week, and as far as I can tell, it cleaned my teeth well.Conclusions

Why conserve apex predators?

Hi everyone! You may have read articles about charismatic predators, such as lions and tigers, being on the verge of extinction. In addition, you may have heard about the controversy over reintroducing wolves to Yellowstone National Park in the 1990s. If you’re like me, you’ve probably wondered if the decreasing numbers of predators is a devastating loss to ecosystems or if their demise simply makes the world a safer place for humans. I wanted to do a post on this fascinating topic.
Predators’ Roles in Ecosystems

Predators’ main role in ecosystems is to rule from the top down, as opposed to producers, who rule from the bottom up. Apex predators keep other consumers in check so they don’t eat producers to extinction. In fact, if an ecosystem’s apex predators are removed, it could cause a trophic cascade, or a major series of changes to the rest of the food web. It could even cause an ecosystem to collapse. For example, humans hunting sea otters decimated kelp forests around the Aleutian Islands. Otters normally eat sea urchins, which feed on kelp. When the otters went extinct in certain areas, urchins multiplied and ate all the kelp. When the otters eventually returned, they reduced the number of sea urchins, allowing “luxuriant” regrowth of kelp. A similar situation happened in Venezuela. In the 1980s, a new dam flooded a valley, creating islands. Before the flood, apex predators like jaguars, mountain lions, harpy eagles, and armadillos left the area. As a result, the islands turned into a hellscape. Howler monkeys living there multiplied out of control and then went mad. In order to defend themselves from being eaten by the monkeys, plants grew thorns and increased their toxicity. Leaf-cutter ants were no longer being preyed on by armadillos, so they carried all the leaves on the islands into their holes, starving the soil of nutrients. Clearly, the ecosystems of the islands collapsed without apex predators (Fraser).
What are some of apex predators’ important roles in ecosystems?
- Apex predators reduce populations of herbivores, preventing them from overeating and decimating ecosystems. For instance, wolves reduce populations of elk, which prevent the elk from eating too many saplings. As a result, more saplings grow to maturity, providing habitat for other animals and soaking up water to prevent floods (“The Importance of Apex Predators for a Healthy Ecosystem”). Ecosystems have delicate checks and balances between predators and prey that likely evolved over millions of years (Dolph). If those balances are upset, it could upend an entire ecosystem.
- As well as eating herbivores, apex predators also eat mesopredators, keeping those populations in check. Mesopredators are mid sized predators like cats and raccoons that are in middle trophic levels. If all the apex predators in an ecosystem die out, mesopredators take over and run rampant. As an illustration, a reduction in lion and leopard populations in Ghana caused olive baboon populations to soar. The baboons are now wildly attacking livestock, damaging crops, and spreading intestinal parasites (Fraser).
- Ironically, the best way apex predators keep herbivores and mesopredators in check is not by eating them, but by creating landscapes of fear that keep them moving. On their own, elk herds will stay in one place and eat all the vegetation there. However, if there are wolves nearby, the elk will browse and then keep moving to look for cover. They will leave small plants and grasses for smaller herbivores and eat less saplings, which ultimately reduces flooding (“The Importance of Apex Predators for a Healthy Ecosystem”). The same principle occurs with mesopredators. On British Columbia’s Gulf Islands, raccoons were eating songbirds, intertidal crabs, and certain fish to near extinction. The raccoons were unafraid since the last large carnivores on the islands had been killed a century before. Then, a research team set up speakers that played dog vocalizations along the shoreline. When raccoons went to those areas to feed, they either left quickly or reduced their foraging. The raccoons’ feeding time was so reduced that the songbird, crab, and fish populations were able to rebound (Mandel). The fear that hearing dogs produced in the raccoons was enough to keep them in check.
- Apex predators can help prey populations by weeding out slow, weak, and diseased animals, which increases the health of the prey populations as a whole (“The Importance of Apex Predators for a Healthy Ecosystem”).
- Apex predators can increase the biodiversity of ecosystems. When wolves were reintroduced to Yellowstone in the 1990s, they controlled the park’s elk, which meant that the elk ate less saplings. As a result, willows and other trees grew on the banks of the streams, cooling the water. The cool water allowed trout and beavers to return for the first time after the vegetation had been decimated by elk. The beavers built dams, which created new ponds. Soon, amphibians and songbirds moved in to enjoy the ponds. The reintroduction of wolves ultimately led to an increase in biodiversity across the whole ecosystem (Fraser).

Jee & Rani Nature Photography.Creepy Crawlies: How Spiders Effect the Vegetation In Their Areas
Spiders are tiny apex predators that prey on insects. Whether they are active hunters or ambush hunters determines the composition of plant communities and the nitrogen levels in their areas. If an area has spiders that actively hunt, they reduce its grasshopper density. As a result, grass and goldenrod dominate since they are being eaten by less grasshoppers. That increases the availability of nitrogen in the area. On the other hand, if an area has spider species that ambush hunt, they will simply force grasshoppers to shelter in goldenrod instead of grass. That leads to a diverse plant community with less available nitrogen (Fraser). Spiders may be small, but they exert impressive control over their ecosystems.What about dangerous apex predators?
Sometimes conserving apex predators can be controversial since those predators are seen as menaces to humans. Sharks are one type of apex predator that are portrayed as deadly monsters in popular culture. However, sharks are actually beneficial to both ocean ecosystems and humans.
What are the benefits of sharks in ocean ecosystems?
Surprisingly, sharks are some of the most vital organisms for the health of ocean ecosystems. There are over 500 species of sharks worldwide. Each species has a different diet, set of behaviors, and role in its ecosystem. Some of sharks’ most important roles are preserving coral reefs, bivalves, and seagrass meadows.
Coral reefs contain one quarter of the world’s marine life. In reef food webs, sharks eat predatory fish like groupers, which eat herbivorous fish that feed on algae. If an area has few sharks, there will be an explosion of groupers, which in turn will eat most of the herbivorous fish. The lack of herbivorous fish will cause an explosion of algae. If the algae in a reef overgrows too much, it will suffocate the corals and kill the reef. That is currently a major problem in Jamaica, where a drop in shark populations has led to the decimation of the island’s coral reefs (“How Do Sharks Help the Ecosystem?”).
Sharks also protect bivalves. Bivalves, such as mussels, scallops, and clams, act as the ocean’s filtration system. They filter phytoplankton out of the water to eat and while doing so, clean the ocean. Bivalves are eaten by Cownose rays. Sharks normally hunt the rays, but if there are no sharks in an area, the rays devour the bivalve population. That leaves the area with no water purification (“How Do Sharks Help the Ecosystem?”).
Finally, sharks preserve seagrass meadows by keeping the turtles and dugongs that eat seagrass moving along. Seagrass meadows store huge amounts of carbon that would otherwise be released into the atmosphere or ocean. As well as accelerating climate change in the atmosphere, carbon dissolved in the ocean makes the water more acidic and harms the organisms that live there (“How Do Sharks Help the Ecosystem?”).

A zebra shark. Part of the article “Carpet shark” on Wikipedia. Courtesy of Wikipedia and Thesupermat. Are sharks dangerous to humans?
Due to the portrayal of sharks in popular culture, people see them as major threats. However, sharks attacks in real life are rare. In 2021, 112 bites on humans were reported worldwide. Nine of those cases were fatal (“International Shark Attack File”). On average, there are about six recorded fatalities from shark attacks per year (Edwards). There may also be a number of unrecorded shark fatalities in developing countries. However, considering that there are 1 billion sharks and 8 billion people worldwide (“How Many Sharks Are In The World?”), six recorded fatalities is fairly small. Fatality rates from shark bites have been declining for decades due to increased public awareness, improved medical treatment, and better beach safety protocols (“International Shark Attack File”). While shark attacks are rare, sharks are dangerous animals so people should educate themselves on shark safety and beach protocols before they swim in the ocean or take part in water sports.
While sharks are rarely a danger to humans, humans are a massive danger to sharks. Roughly 100 million sharks are killed by humans each year (Sen), which is one tenth of the world’s current shark population (“How Many Sharks Are In The World?”). As a result, an estimated 25% of shark and ray species are threatened with extinction. Sharks are killed for a number of reasons. One of the main ways humans kill sharks is shark finning. Shark fins are used in shark fin soup, a delicacy in some places. Unfortunately, shark finning is very cruel. After fishers catch a shark, they will usually saw its fins off while it is still alive. Then, they will toss it overboard. The live shark cannot swim without its fins, so it sinks and drowns. Shark finning is illegal in 70 countries and regional bodies, but it is not illegal globally. Many other sharks are killed from being caught as bycatch. Bycatch are marine animals that are accidently caught in fishing nets. Estimated tens of millions of sharks are killed each year from being bycatch. A third cause of the decline of the shark population is nursery and habitat destruction from coastal development and destruction of coral reefs and mangrove swamps (Sen). People need to remember that the ocean is the sharks’ home. When humans enter the water, they are doing so at their own risk. A decline in shark populations should not be seen as a benefit to humans, but rather a danger to aquatic ecosystems.
Sharks are actually very helpful to humans. Shark related tourism is a boon to countries’ economies. It contributes about 113.8 million USD to the economy of the Bahamas annually (Sen), as well as 42.2 million USD to Fiji (Sen) and 25.5 million USD to Australia. Reef related tourism is an even bigger money maker, with Australia receiving billions of dollars from it every year (“How Do Sharks Help the Ecosystem?”). Sharks also protect types of seafood that humans eat. A decrease in sharks along the eastern seaboard led to an explosion of rays that killed an old scallop fishery. If sharks had been protected in the area, the fishery would have remained intact (Fraser).
The best ways for humans to protect sharks are only buying certified sustainable seafood, avoiding shark meat and products, and encouraging the creation of Marine Protected Areas along coastlines. Shark products to avoid include liver oil, jaws, teeth, shark leather, and flake, which is shark meat (Sen).
Human Deaths Caused by Apex Land Predators Versus Other Animals
This chart compares the numbers of human deaths caused by wolves and lions versus the numbers of deaths caused by other animals.

Hippopotamuses, which are a prey of lions, actually kill 15 times more humans than lions themselves. The most dangerous animals in the world are mosquitoes and humans.

This post covered the benefits of conserving apex predators and also statistics on how dangerous certain predators are to humans. I find this information fascinating and want to spread more awareness about the benefits of apex predators in the future.

Highlights of 2022

Hi everyone! I know its easy to be anxious about the earth. While it is important to be informed and care about the environment, too much anxiety is counterproductive. I wanted to take the time to inspire you with positive environmental news from 2022.

This is a photo of the preamplifiers of the National Ignition Facility at the Lawrence Livermore National Laboratory. They increase the energy of the laser beams as they head toward the target chamber where nuclear fusion takes place. Image courtesy of Wikipedia and the Lawrence Livermore National Laboratory. Nuclear Fusion Breakthrough
On December 5, scientists at the Lawrence Livermore National Laboratory in California had a breakthrough in nuclear fusion energy production. For the first time ever, they set up a nuclear fusion reaction that produced more energy than it took to create. To catalyze the reaction, the laboratory’s laser complex shot 192 lasers at a tiny capsule containing one tritium isotope and one deuterium isotope, both of which are isotopes of hydrogen. The isotopes vaporized, releasing a huge amount of energy. The experiment had been tried many times before, but the energy input of the lasers had always exceeded the output of the fusion. On December 5, however, the isotopes were held in a thicker capsule, which made them hot and dense enough that they fused and released more energy than the lasers expended. The lasers hit the isotopes with roughly two megajoules of energy, and the fusion produced about three megajoules, generating a gain of 1.5 (“Nuclear Fusion Breakthrough: The Future of Clean, Limitless Energy”). That energy gain would be enough to boil 2.5 gallons of water (Nilsen). While that is not a lot, it shows that nuclear fusion can be a viable energy source.
Why is nuclear fusion special?
Nuclear fusion would make an excellent energy source since it runs off easily accessible hydrogen and produces efficient, carbon-free energy. It is much safer than nuclear fission, which is used in current nuclear power plants. Nuclear fission splits atoms to produce energy and poisonous waste, while fusion fuses atoms to yield energy and harmless byproducts (“Nuclear Fusion Breakthrough: The Future of Clean, Limitless Energy”). The atoms being fused are deuterium and tritium, which are isotopes of hydrogen. As an illustration of how efficient nuclear fusion is, if a little tritium was fused with the amount of deuterium from a glass of water, the energy from the reaction would power a house for a year (Nilsen, Ella and Rene Marsh). The byproducts of nuclear fusion are helium nuclei and high energy neutrons (“DOE Explains… Nuclear Fusion Reactions”).Dr. Kim Budil, the director of the Lawrence Livermore National Laboratory, predicts that fusion power plants will be built “with a few decades of research and investment” (“Nuclear Fusion Breakthrough: The Future of Clean, Limitless Energy”). Nuclear fusion power plants might even take off as quickly as nuclear fission power plants did. In 1942, the first nuclear fission reactor ran for five minutes in Chicago. Fifteen years later, the first nuclear power plant was installed in Pennsylvania (Nilsen). In addition, magnetic nuclear fusion is being explored as well as fusion caused by lasers. Magnetic fusion involves tokamaks, or doughnut shaped devices that use magnets to squeeze plasma into small shapes (“Nuclear Fusion Breakthrough: The Future of Clean, Limitless Energy”).

Photo by Pixabay on Pexels.com 2022 Has Seen A Huge Increase in Renewable Energy
This past year has seen a major increase in renewable energy. The world’s electricity demand rose by about 3% since 2021, but solar, wind, and hydroelectric power met the additional demand for the first half of 2022. That reduced carbon emissions by 230 million metric tons, or the equivalent of 49 million gas powered cars (“Renewables have saved 230 million tonnes of CO2 emissions so far in 2022”).
The overall increases in renewable energy are likely due to changes in the United States and Europe. Solar and wind have grown 58% in the United States since 2019. As a result, 2022 marked the second year that renewables produced more energy for the country than coal, satisfying about 22% of its energy usage (“Renewables to produce more energy than coal for the first time this year”). European countries have been taking even more drastic steps. Portugal, Denmark, and Austria have goals to be powered solely by solar, wind, and hydroelectric in 2030, while the Netherlands aims to be powered solely by those renewables plus nuclear. (“These EU countries are aiming for 100% clean power by 2030”). Although Greece is not aiming to be 100% renewable in 2030, it made history on October 7 by being solely run on renewable energy for five hours (“Major milestone for Greek energy as renewables power 100% of electricity demand”). Renewables are starting to become a major provider of the world’s electricity.

Photo by Rudolf Jakkel on Pexels.com Millions of Trees Are Being Planted for Reforestation Efforts
This past year, there have been several massive reforestation projects. Forest cover is important since trees produce oxygen and absorb carbon dioxide, prevent flooding by holding water, and keep areas moist through transpiration. In the United States, the federal National Forest Foundation planted over eight million trees (“2022 National Forest Foundation Year in Review”). Some of the trees are in forests being restored after wildfires, such as in Oregon’s Willamette National Forest, or after being destroyed by beetles, such as in Grand Mesa National Forest in Colorado. Others have not experienced natural disasters but need more trees to be healthy, thriving ecosystems (Perez-Watkins). In addition, a charity called One Tree Planted has been planting trees and vegetation all over the world. While statistics have not been released for the nonprofit’s work in 2022, in 2021 the organization’s volunteers planted about 25,588,232 trees through 166 projects in 42 countries (“Our 2021 Planting Report”). During autumn 2022, One Tree Planted supported events in 29 countries to plant 39,558 trees and 6,144 shrubs. Some countries served by the organization include Columbia, Tanzania, Thailand, and the United States (Weeden).

States and Countries are Cutting Down Single Use Plastics
Multiple parts of the world have been reducing the use of single-use plastics and replacing them with either biodegradable packaging or reusable items. In 2022, California passed a law demanding a 25% drop in single-use plastics in the state by 2032. It also set a goal for 30% of plastic items bought and sold in California to be recyclable by 2028, created a pollution mitigation fund paid by plastic companies, and set strictly enforced criteria for polystyrene recycling that could lead to a ban on the material. California’s decision to cut down on plastics should reduce worldwide pollution since California is a major source of it (Anguiano).
The UK and the European Commission are taking even more extreme measures to reduce single-use plastics. Single-use plastic plates, cutlery, balloon sticks, and some types of polystyrene cups will be phased out and eventually banned in the UK. The UK government intends to replace the plastics with biodegradable alternatives (“Single-use plastic items to be banned in England – reports”). The European Commission, on the other hand, wants to make more items reusable. For instance, they decreed that 20% of takeaway drink cups in their domain would be reusable by 2030 and 80% would be reusable by 2040. As a result, McDonald’s France and other European companies are testing out reusable packaging (“This reusable McDonald’s packaging went viral”).
Seaweed Packing
Scientists are doing their part by developing new types of biodegradable packaging. One popular option is seaweed. A number of startup companies have begun selling seaweed products, including bags, cups, trays, sauce packets, takeout boxes, pipettes, drinking straws, vegan leather, “plastic” films, and waterproof cardboard coatings (“10 Seaweed Packaging Startups You Need to Know”). In 2022, researchers from Flinders University in Australia partnered with a German biomaterials developer to specifically create grease proof wrappings. The packaging is effective and safer than grease proof paper, which contains plastic and sometimes dangerous chemicals like PFASs (“Your burger could soon come wrapped in packaging made from seaweed”).Efficient Sea Salt Batteries Could Replace Lithium Batteries
Batteries are necessary to everything from wall clocks to smart phones to electric cars. As wind and solar power take off, batteries are needed to store their intermittent electricity. Many batteries are built with rare metals such as lithium, graphite, and cobalt. Since lithium is the main metal used in batteries, the European Union alone might need 18 times more lithium by 2030 to meet their renewable energy goals. Unfortunately, lithium is expensive (“’Significant breakthrough’: This new salt sea battery has four times the capacity of lithium”), and its mining causes a number of environmental problems, including water shortages and air contamination (Campbell). In order to combat those problems, scientists at the University of Sydney invented a new battery that runs on sodium sulfur, or molten salt processed from sea water. It stores four times the energy of a lithium battery and is much cheaper. According to the battery’s inventors, it also has an “ultra-long life at room temperature” (“’Significant breakthrough’: This new salt sea battery has four times the capacity of lithium”). Sea salt batteries are a welcome alternative to lithium ones.

A final piece of good news is that there is a large community of humpback whales in the waters near Australia! Humpbacks were removed from Australia’s threatened species list in 2022. They were originally put on the list since their numbers had decreased to about 1,500 whales at the height of the whaling industry. Now, there are about 40,000 whales in the waters near Australia. The whales are still protected by a number of international and domestic laws, including statutes against whaling (Wahlquist).

Powering the Future: The Reality of Fuel Cells

Hi everyone! I have an interest in fuel cells, so I decided to write a post on them. Fuel cells are a hot topic right now and are being investigated as an environmental option to power cars, trucks, buildings, and planes. They run on hydrogen, so about a year ago, the United States government set goals to establish hydrogen hubs across the country and reduce the cost of green hydrogen to 1 U.S. dollar per kilogram (Silverstein). Fuel cells and fuel cell vehicles are specialized technology that will continue to become more prevalent in the future.
What are fuel cells?
Although fuel cells are a hot topic, they are not a new one. The first fuel cells were built around 1842 by William Grove, who managed to both generate an electric current and produce water through a reaction involving hydrogen and oxygen. Grove’s fuel cells involved series circuits of platinum electrodes. Each “cell” of the series had two platinum electrodes, one in a tube filled with oxygen and one in a tube filled with hydrogen. The bottoms of the tubes and electrodes were dipped in a dilute sulfuric acid solution, which conducted current between the electrodes (Poffenberger).

An image of Grove’s fuel cell. Courtesy of Wikipedia. Fuel cells have changed a bit over the past 180 years, but the basic idea is still the same. All fuel cells have a negative electrode, or anode, and a positive electrode, or cathode, that are separated by an electrolyte. A fuel, like hydrogen, is fed to the anode, while air is fed to the cathode (“Fuel Cell Basics”). A catalyst at the anode separates hydrogen into its protons and electrons, which each take a different path to the cathode. The electrons take an external circuit, which creates an energy flow, while the protons travel directly through the electrolyte. When both the electrons and protons reach the cathode, they react with the oxygen there to produce water and heat (“Fuel Cells”).
Fuel cells are similar to batteries, but they never run down or need recharging. They produce electricity and heat as long as they have fuel (“Fuel Cell Basics”).

Scheme of a proton-conducting fuel cell by R. Dervisoglu. Courtesy of Wikipedia. There are many types of fuel cells, including direct-menthol and alkaline varieties, but polymer electrolyte membrane (PEM) fuel cells are the best for cars. In a PEM fuel cell, hydrogen and oxygen react to make water, electricity, and heat. Regenerative or reversible fuel cells are useful for energy storage. They can both make electricity and water out of hydrogen and oxygen and use electricity to separate water back into hydrogen and oxygen, which can later be reacted to produce more electricity (“Fuel Cell Basics”).
How are fuel cell vehicles better than gasoline powered cars?
- Fuel cell cars produce no tailpipe emissions, but only water vapor and warm air (“Fuel Cell Electric Vehicles”). Their lack of emissions is helpful since regular gasoline powered cars emit not only lots of greenhouse gases but also poisonous smog including nitrogen oxide, carbon monoxide, and formaldehyde. Smog triggers dangerous lung diseases like asthma, emphysema, and chronic bronchitis. In 2018, about 125 million people in the U.S. lived in unhealthy air (“Light Duty Vehicle Emissions”).
- Hydrogen is non toxic and lighter than air, which means that it dissipates quickly. As a result, a person is unlikely to be poisoned by a hydrogen leak (“Safe Use of Hydrogen”).
- Fuel cell cars are more efficient than gasoline powered cars, partially due to their regenerative braking systems. Their braking systems capture the energy that would normally be lost during braking and store it in a battery to be used later (“Fuel Cell Electric Vehicles”).
- Fuel cells diversify the transportation economy and make the United States less dependent on foreign oil and gas (Accardi).
How are fuel cells better than other electric cars?
- The main benefit that fuel cell cars have over electric cars is that they fuel up in about four minutes (“Fuel Cell Electric Vehicles”), while electric cars take at least half an hour to charge and usually much longer. As an illustration, a Tesla Model 3 Long Range takes 10 hours to fully charge at a standard Level 2 charging station (Loveday). Fuel cell cars travel about 300 miles after a four minute fuel up (“Fuel Cell Electric Vehicles”), while average electric cars travel the same distance after charging for many hours (Bogna).
What are some drawbacks to hydrogen fuel cell cars?
Fuel cell cars are not perfect, but most of their problems will be solved as new technology and infrastructure are developed.
- The biggest problem with fuel cell cars is that most hydrogen is not green. At least 95% of it is produced in reactions that involve coal and natural gas and that release greenhouse gases (Silverstein, “Hydrogen Fuel Basics”). However, the production emits only half the greenhouse gases of combustion engine cars and uses up only one tenth of the petroleum (“Hydrogen Production: Natural Gas Reforming”). A small percentage of hydrogen is made through renewable energy and other green methods. In June 2021, the United States Energy Department decided to increase the availability of green hydrogen by setting a goal to reduce its cost from 5 dollars per kilogram to 1 dollar per kilogram in one decade (Silverstein).
- Another concern about hydrogen fuel is that it can light on fire more easily than gasoline or natural gas. It has a wider range of flammable concentrations in air and needs less ignition energy. However, hydrogen is safe as long as the systems containing the fuel are well designed, and people are educated on how to handle it properly (“Safe Use of Hydrogen”).
- Fuel cell cars are currently very expensive. The few cars on the market sell for about USD 80,000 each. As they become more common, the cost will go down (“Hydrogen fuel cell cars: everything you need to know”).
- Currently there is little infrastructure for fuel cell cars, including few fueling stations. A year ago, Congress passed a Bipartisan Infrastructure Bill that includes 7 billion dollars to set up six to ten regional hydrogen hubs across the country. The goal of the hubs is to connect producers and consumers and accelerate the use of clean hydrogen (Silverstein).
- At the moment, hydrogen tanks take up a lot of space, so fuel cells can only be used in large models of cars. That is one of the reasons fuel cell cars are more expensive. (“Hydrogen fuel cell cars: everything you need to know”).
How is hydrogen produced in the first place?
Most hydrogen is produced through either natural gas reforming or electrolysis. Natural gas reforming occurs when steam reacts with hydrocarbon fuel to produce hydrogen, while electrolysis is a process in which an electrolyzer separates water into hydrogen and oxygen with an electric current. Other methods of hydrogen production are either solar-driven or biological. Some solar-driven production methods are photobiological, where bacteria and green algae produce hydrogen through photosynthesis, or photoelectrochemical, where semiconductors separate water into hydrogen and oxygen (“Hydrogen Fuel Basics”). One biological method of hydrogen production is microbial biomass conversion, where microbes release hydrogen as they consume and digest organic matter (“Hydrogen Production: Microbial Biomass Conversion”). While the idea of cultivating microorganisms to produce hydrogen sounds bizarre, oil-eating microbes are already being used to produce hydrogen from abandoned oil wells (Blain), while vinegar processing ones were able to extract 91% of the hydrogen out of vinegar (“Microbes Churn Out Hydrogen at Record Rate”).How does a fuel cell car work?
Fuel cell cars have propulsion systems like those of electric vehicles, but their energy is stored as hydrogen gas in a tank instead of in a battery. Their fuel is converted to electricity by the fuel cell (“Fuel Cell Electric Vehicles”).

Courtesy of afdc.energy.gov/vehicles/how-do-fuel-cell-electric-cars-work. Hydrogen fuels everything in the car either directly or indirectly. Hydrogen fuel goes from the fuel tank to the fuel cell, where it is converted into electricity. The battery pack also holds electricity that it absorbs from regenerative braking. Both sources power the electric traction motor and transmission, which turn the car’s wheels. The power electronics controller regulates the amount of electricity that enters the electric traction motor, the speed of the motor, and its torque, while the thermal cooling system makes sure that everything stays at the correct temperature. Fuel cell cars also have auxilary batteries, which provide electricity to start the cars and run vehicle accessories. Electricity is transferred from the battery pack to the auxilary battery by the DC/DC converter, which converts the high voltage power of the battery pack to a lower voltage. (“How Do Fuel Cell Electric Vehicles Work Using Hydrogen?”).
From Forklifts to Airplanes: Larger Fuel Cell Powered Vehicles
Large vehicles such as planes, trains, ships, and long-haul trucks are difficult to make electric, but it is possible for them to run on fuel cells. A study by Clean Sky 2, a respected aeronautical research partnership, estimates that the first hydrogen powered aircraft could be produced by 2035, and aircraft for longer flights could be ready by 2050. Airlines will likely be eager to use hydrogen fuel since many of them are testing environmental alternatives to regular jet fuel. As an illustration, British Airways, Jet Blue, Scandinavian Airlines, United Airlines, Virgin Australia, and Virgin Atlantic have all tried biofuels on commercial flights, while Delta recently purchased 385 million gallons of a new “greener” jet fuel.
Air transportation is not the only kind investigating hydrogen fuel. About 20,000 hydrogen powered forklifts are being used by Walmarts and Targets across the country. FedEx drives a fuel cell powered delivery truck in New York State. In addition, National Grid intends to become a corporate buyer of hydrogen fuel once it is more established. As the costs drop and the government sets up regional hydrogen hubs, more vehicles and appliances will be run on hydrogen (Silverstein).Conclusions
Fuel cells will be more prevalent in the future, so learning about them now will come in handy. I want to buy a fuel cell car, but I am planning to wait until they get cheaper!

Organized Decay: The Art of Composting

Hi everyone! Most of you have probably heard of composting. Its a method of recycling organic items, such as vegetable scraps, so that they don’t end up in landfills. My family has a low maintenance compost pile in our backyard, and many other people have compost bins that they use to create nutrient-rich garden soil. Here I’ll answer some questions about the benefits of composting, what can be composted, how to compost in an apartment, and compost’s uses.
Why compost?
Composting is good for the environment because it prevents food waste and other organic material from going to landfills. Landfills take up space and produce methane that contributes to climate change. In addition, compost has many uses, including replenishing soil and nourishing gardens (Dempsey).
How can I compost?
Composting is fairly easy. My family has a low-maintenance compost pile behind our house where we throw most of our food scraps and yard waste, including egg shells, vegetable peels, and dried leaves. We ignore it most of the time, but occasionally we churn it and put some of its soil into our garden.
My family’s composting method is useful for anyone who has enough land. However, many people live in apartments or have small yards where they cannot keep large piles of rotting vegetation. Luckily, there are other methods to compost in apartments.

Composting in an Apartment
There are multiple ways to compost in an apartment, including old fashion bins, worm bins, compost tumblers, electric composters, and community composting.
- Old fashioned compost bins are fairly self explanatory. A person can buy one online or simply modify a trash can or similar container. A good size for a compost bin is three feet square. In order for compost to decompose properly without smelling, it needs a balance of browns, or carbon-rich materials, and greens, or nitrogen-rich materials. It is also helpful to keep one’s bin damp and turn it regularly (“How to Use a Compost Bin”).
- Worm bins are different than old fashioned compost bins in that they only involve putting newspaper, dirt, compost, and worms into a plastic bin. The worms process the compost, and the bins themselves are small. A good worm bin size is about 15 inches deep by 25 inches wide (Dempsey).
- Compost tumblers are bins that are turned by hand cranks. They are small and require less maintenance than old fashioned compost bins (Dempsey).
- Electric composters disintegrate compost by grinding it to a pulp. They have no smell, easily get rid of food waste, and process items that are difficult to compost, such as meat scraps and avocado stones. Afterwards, the byproducts of electric composters can be used as fertilizer. Unfortunately, electric composters are very expensive (Dempsey).
- Community composting comes in handy if a person’s apartment building or town has a designated space for it, such as on the roof of a building or next to a community garden. In addition, people can buy into composting services, which are similar to trash removal services.
What can be composted?
As a rule of thumb, compost is nontoxic organic material. My family regularly composts fruit and veggie scraps, egg shells, coffee grounds, stale bread, dropped pasta, dead flowers, and hair, and occasionally composts paper and dead leaves. Other potentially compostable items include paper, yarn, and thread (“What CAN Be Composted in a Home Composting Bin?”). If a person is using a bin, they need to balance their browns, or carbon-rich materials, with their greens, or nitrogen-rich materials. Greens include fruit and veggie scraps, yard waste, teabags, coffee grounds, and manure, while browns include scrap paper, non-glossy newspaper, dry yard waste, straw, sawdust, and egg cartons. In general, it is smart to have twice the browns in one’s compost bin as greens, which keeps it from smelling (“How to Use a Compost Bin”).
Radical Composting: Terramation
Did you know that some people opt for their remains to be composted? Terramation, or human composting, is an environmental end-of-life alternative to burial or cremation (O’Donnell). It involves composting human remains in a steel vessel with straw, alfalfa, and wood chips to produce garden soil. Families of the deceased can take the compost home and use it for conservation projects or to start a memorial garden or orchard (Bush). So far, terramation is legal in Washington, Colorado, Vermont, and California. It is fairly new but is becoming more common, as evidenced by 1,200 people who have signed up to have their remains composted by Recompose, a company in Seattle (O’Donnell).When is it safe to compost paper?
Paper is a helpful compost component because it absorbs moisture and is a source of carbon. However, it is bad to compost papers that are heavily inked, have special coatings, or have been in contact with man-made chemicals. Papers that are usually safe to compost include newspaper, printer paper, cardboard, shredded paper, greasy paper, plain tissue paper, and envelopes. On the other hand, papers that usually shouldn’t be composted include greaseproof paper, heavily inked paper, glossy paper, receipts, and any paper that has chemicals on it (“What papers can be composted and why?”).
What can’t be composted?
Anything with dangerous chemicals or germs shouldn’t be composted. Items to avoid composting include plants contaminated with herbicides and pesticides, diseased plants and leaves, pet and human feces, lime, coal, pressure treated lumber, and paper with excessive inks (“What CAN Be Composted in a Home Composting Bin?”).
Radical Composting: Composting Toilets
Although human and animal waste is too toxic to compost in a pile or bin, it can be dealt with by a composting toilet. Composting toilets collect human waste and turn it into a humus-like substance. Contrary to how they might sound, composting toilets are sanitary and odorless. They are also much better for the environment. They create a nontoxic fertilizer, while ordinary sewage systems frequently create water pollution. In addition, they greatly reduce water consumption since flush toilets are responsible for around 30% of households’ water usage. The toilets can be either portable or permanent and are especially useful in remote places that have neither town sewer systems nor septic tanks (Vartan).Some items are bad to compost, but are not necessarily bad for the environment. Pine needles, wood ash, and charcoal shouldn’t be added to a compost pile because they decompose poorly and are not good for new soil. In addition, animal products can technically be composted, but are usually not because they smell and attract animals. Products that are not typically put in compost include meat, fish, bones, dairy, eggs, and grease (“What CAN Be Composted in a Home Composting Bin?”). Other reasons most people avoid composting meat are that mushy meat restricts airflow and feeds anaerobic bacteria that produce unwanted odor and acidity (Boyd).
Meat: To Compost Or Not To Compost
Although most people avoid composting meat, it can be done in a compost pile that is hot and well-aerated. The pile should reach a temperature of about 140 to 160 degrees Farenheit at least once a week(Boyd). While 140 to 160 degrees Farenheit sounds extreme, bacteria will naturally heat up compost to over 130 degrees Farenheit as long as the pile has a good balance of greens and browns and is around 3 feet deep (“How do I heat up my compost pile?”). Before a person puts raw meat in their compost, they should precook it to kill E. coli and other dangerous bacteria and cut it into small pieces. It is important that they turn their compost pile frequently and keep the meat scraps in its middle (Boyd).
Conclusions
I hope this has been helpful for those of you who want to understand composting better and are interested in having your own pile or bin. I am personally inspired to compost paper in my family’s pile.
