Plastic pollution is a serious problem that is affecting our planet. Plastic is everywhere and is used to make many things, from shopping bags to food wrappers and toys. Plastic is so common because it is cheap and useful, but it is also harmful to the environment. This is because plastic does not break down quickly and can take up to 450 years to decompose. This means that plastic waste can stay in the natural world for a long time, causing damage to the environment and harming animals. Humans produce around 300 million tons of plastic waste each year, and a large amount of this ends up in our oceans, where it is eaten by marine animals or entangles them. Plastic pollution is also harmful to humans as we can end up eating contaminated seafood and inhaling toxic microplastics.

What You'll Learn
Plastic takes over 400 years to decompose
Plastic is an incredible human-made substance that can be used to create a variety of useful things, such as bike helmets, car airbags, and even life-saving medical supplies. It is durable and long-lasting, but this also makes it harmful to the environment. Plastic takes a very long time to decompose, or break down—over 400 years! This is because plastic is not natural and does not easily break down in the environment like other materials.
Plastic was first created in 1907, and since then, it has become a huge part of our lives. We use plastic for all sorts of things, from shopping bags to water bottles and food packaging. It is so useful that we now produce about 359 million metric tons of plastic every year. That's a lot of plastic! However, about half of the plastic we make is only used once and then thrown away. This is called "single-use plastic," and it is a big problem because plastic takes so long to decompose.
When plastic is not recycled, it is often dumped in landfills, burned, or sent to other countries. Even when it is recycled, it is usually "downcycled," which means it is turned into something else that will also need to be thrown away. This is why reducing our plastic use is so important. Plastic can end up in our oceans and other natural environments, where it can harm animals and pollute the water and soil.
So, what can we do about it? We can start by reducing our use of single-use plastic. This means choosing reusable water bottles, shopping bags, and straws instead of disposable ones. We can also ask our parents to buy loose fruits and vegetables instead of those wrapped in plastic. Recycling the plastic we do use is also important, but it's crucial to make sure that the plastic is truly recyclable and properly cleaned. Finally, joining beach or community clean-up events can help keep our environment clean and protect wildlife!

Plastic in the ocean is dangerous for marine animals
Plastic pollution is a big problem for our oceans and the animals that live there. Plastic can end up in the ocean in many ways, from being dumped directly by people to being carried by winds and rivers. Once plastic is in the ocean, it can have harmful effects on marine life. Marine animals can get hurt by plastic in a few different ways. They may become entangled in larger pieces of plastic, such as old fishing nets or six-pack rings, which can restrict their movement, cause injury, or even lead to death. Smaller pieces of plastic, known as microplastics, can also be mistaken for food and ingested by marine animals. These tiny pieces of plastic can build up in their stomachs, making them feel full without providing any real nutrition. This can lead to malnutrition and even starvation in some cases.
Plastic pollution also affects the ocean ecosystem as a whole. As plastic breaks down into smaller and smaller pieces, it never really goes away but instead becomes microplastics. These microplastics can absorb toxic chemicals from the ocean environment, such as pesticides and industrial pollutants. When marine animals ingest these contaminated microplastics, the toxins can build up in their bodies, leading to health issues and even death. Additionally, some types of plastics can release chemicals directly into the water, impacting the health of marine life and the overall ocean environment.
Plastics can also impact the ocean food chain. As smaller marine animals ingest microplastics, they can then be eaten by larger animals, causing the transfer of plastics and toxins up the food chain. This process is known as bioaccumulation. At the top of the food chain are apex predators, such as sharks and tuna, which may consume large amounts of plastic and toxins by eating smaller animals. This can have detrimental effects on their health and population numbers.
Additionally, plastic pollution can affect the habitats and breeding grounds of marine animals. For example, coral reefs, which are vital habitats for many marine species, can become entangled in plastic debris, blocking sunlight and damaging the coral. Plastic debris can also end up on beaches, impacting the nesting sites of sea turtles and the breeding grounds of other marine animals. Overall, plastic pollution poses a significant threat to marine life. It is important to reduce, reuse, and recycle plastic items to help minimize the amount of plastic entering our oceans. By taking care of our planet and its oceans, we can help ensure the health and well-being of marine animals for generations to come.

Plastic waste in the ocean looks like food to marine animals
Plastic pollution is a big problem for our oceans and the animals that live there. Plastic is a man-made material that is very useful to us. We use it for bike helmets, car airbags, medical supplies, and water bottles. The problem is that we use too much plastic and often only use it once before throwing it away.
Every year, about 8.8 million tons of plastic end up in our oceans. This plastic waste can float on the surface of the ocean, forming "trash islands". It can also be broken down into tiny pieces called microplastics. These microplastics can be eaten by small sea animals and then move up the food chain to bigger animals, including us! This is because plastic attracts toxic chemicals released from industry and agriculture, and the concentration of these chemicals increases as they move up the food chain.
We can help by using less plastic and recycling it properly. We can use reusable water bottles and shopping bags, and buy loose fruit and vegetables instead of those wrapped in plastic. We can also join beach cleanups to help keep our oceans and marine animals safe!

Plastic waste affects human health
Secondly, plastic waste releases toxic chemicals into the environment, which can be harmful to human health. The extraction and transport of plastic feedstocks from fossil fuels release toxic substances into the air and water, with over 170 fracking chemicals known to have negative human health impacts, including cancer, neurological damage, and reproductive toxicity. These toxins can enter the human body through inhalation, ingestion, or skin contact, leading to health issues in various organ systems such as the respiratory, nervous, and gastrointestinal systems.
Additionally, plastic waste can contaminate food chains through agricultural soils and water sources. Microplastics, which are small pieces of degraded plastic, can be ingested by humans and have been linked to health issues such as inflammation, oxidative stress, and genotoxicity. These microplastics can also bind to other chemicals in the environment, forming complex toxic compounds that can further impact human health.
The impact of plastic waste on human health is a growing concern, and it is important to address this issue through reduced plastic production, improved waste management practices, and the adoption of reusable alternatives to single-use plastics. By understanding the health risks associated with plastic pollution, individuals can make informed decisions to protect their health and the environment.

How to reduce plastic pollution
Plastic is a man-made material used to make lots of useful things, like bike helmets, car airbags, and medical supplies. Plastic is also used to make water bottles, which can bring clean drinking water to people who need it. The problem is that plastic is not biodegradable, meaning it does not break down and return to nature like an apple core or a piece of paper. Instead, it stays in the natural world for hundreds of years, causing damage to the environment and wildlife.
Plastic pollution happens when plastic waste is not disposed of properly and ends up in the ocean or other natural habitats. This can happen when people dump large amounts of waste directly into the sea, known as 'ocean dumping', or when plastic litter on the ground blows into creeks and rivers, eventually making its way into the ocean. It can also be caused by plastic waste being swept in from the coastline or carried to rivers from the streets during heavy rain. As a result, over 700 species of marine animals have been reported to have eaten or become entangled in plastic.
To reduce plastic pollution, we can make some simple changes in our daily lives:
- Use reusable water bottles instead of single-use plastic bottles.
- Say no to plastic straws and use reusable alternatives made from bamboo, metal, or glass, or make your own paper straws.
- Bring your own multi-use shopping bags when you go grocery shopping instead of using plastic bags.
- Buy loose fruit and vegetables instead of those wrapped in plastic packaging.
- Recycle as much plastic as you can and ensure that your waste is truly recyclable by checking the number on the bottom of your containers.
- Buy in bulk and store food in reusable glass jars instead of buying smaller quantities that require more plastic packaging.
- Pack eco-friendly lunches for school or trips by using reusable containers and switching from cling film to sandwich pockets or beeswax wraps.
- Make green goody bags for birthday parties by including homemade treats and eco-friendly gifts like paper notebooks and flower seeds instead of plastic toys.
- Choose second-hand toys, trinkets, and electronic gadgets from thrift stores, garage sales, or online instead of buying new plastic items.
- Participate in organised beach clean-ups to help keep seasides clean and reduce plastic pollution.

Frequently asked questions
Plastic pollution is when plastic waste ends up in our environment, especially in the ocean. Humans produce around 300 million tonnes of plastic waste every year, and 8 million tonnes of this ends up in the ocean.
Plastic pollution happens when plastic is not disposed of properly. In the United States, plastic that is not recycled is dumped in landfills, incinerated, or shipped overseas. Plastic waste in the ocean often comes from "ocean dumping", when people illegally tip large amounts of waste into the sea. However, around 80% of plastic in the sea comes from land-based sources.
Plastic pollution is bad because it harms wildlife and the environment. Plastic waste in the ocean can be eaten by marine animals or entangle them. Over 700 species of marine animals have been reported to have eaten or been entangled in plastic. Plastic is also not biodegradable, meaning it stays in the natural world and causes damage for a very long time. It can take over 400 years for plastic to decompose, and during this time it breaks down into smaller pieces called microplastics, which are harmful to humans and animals. Microplastics have been found in seafood, the soil where we grow our food, and the air we breathe.
