Plastic pollution is a pressing issue that is causing significant harm to ocean life. With the widespread use of plastic, an estimated 8 million tonnes of plastic waste end up in the ocean each year, posing a severe threat to marine ecosystems. Marine animals, such as fish, turtles, seabirds, and seals, are vulnerable to the detrimental effects of plastic pollution. They can easily become entangled in plastic debris, leading to injuries, starvation, and even drowning. Additionally, these animals often mistake plastic for food, ingesting toxic microplastics that can cause internal damage and increase the risk of death. The impact of plastic pollution extends beyond marine life, as it also affects human health and economies. It is crucial to address this global crisis through improved waste management, reduced plastic production, and the adoption of sustainable alternatives to protect ocean life and ensure a healthier planet for future generations.

What You'll Learn
Plastic waste can trap and kill marine animals
Plastic waste in the ocean can easily trap and kill marine animals. Unlike humans, animals do not have hands to free themselves if they get trapped in plastic waste. For example, they can get tangled up in plastic waste like fishing nets or plastic packaging rings, which can prevent them from eating, swimming, or breathing, and can even cause them to drown.
Plastic waste can also break down into smaller pieces called microplastics. These are so small that they cannot be seen by the human eye, but they are still very harmful. Microplastics can be eaten by marine animals, who might think they are food. This can make the animals feel like they are full and stop them from eating real food, which can cause them to starve. It can also cause internal injuries and death. Research shows that this has happened to many sea turtles and seabirds, and it is estimated that up to 1 million seabirds die from eating plastic every year.
Large plastic waste, like fishing nets, can also trap and kill bigger marine animals like whales. For example, a whale was found dying off the coast of Norway with 30 plastic bags and a lot of plastic packaging in its stomach. Another whale was found stranded near Seattle with more than 20 plastic bags and other rubbish in its stomach. These whales died because they ate plastic waste, but they could also have been trapped by it.
Plastic waste in the ocean is a very serious problem that can harm and kill many different kinds of marine animals. It is important to reduce plastic waste and to clean up the ocean to protect marine life.

Plastic waste is ingested by marine animals
Plastic pollution in the ocean is a serious issue that affects marine animals in many ways. One of the most concerning impacts is when marine animals accidentally eat or ingest plastic waste. This happens because plastic can look like food to animals, especially when it breaks down into smaller pieces called microplastics, which are too small to be seen by the human eye.
Fish, for example, often mistake small plastic pieces, such as pellets, for food. When molluscs like mussels and oysters filter seawater to feed, they also end up taking in microplastics. Even apex predators like great white sharks and orcas are at risk due to the cumulative impact of microplastics in the food chain. As plastic breaks down, it can be ingested by smaller creatures, which are then eaten by larger predators, leading to a build-up of toxins in their bodies.
Sea turtles are also greatly affected by plastic waste. Research indicates that half of the sea turtles worldwide have ingested plastic. A recent study found that sea turtles that eat just 14 pieces of plastic have a higher risk of dying. Young sea turtles are especially vulnerable because they are less selective about what they eat and tend to drift with ocean currents, just like plastic does.
Seabirds are another group that suffers from plastic ingestion. It is estimated that 60% of all seabird species have eaten plastic, and this number is predicted to rise to 99% by 2050. Seabirds can choke on plastic or have their stomach capacity reduced, leading to starvation. Dead seabirds are often found with their stomachs full of plastic waste, showing the deadly consequences of plastic pollution.
Marine mammals, such as whales, dolphins, and seals, are also at risk of ingesting plastic. They may eat plastic bags, packaging, or other plastic debris, causing internal injuries or a false sense of fullness that leads to starvation. Critically endangered species like Hawaiian monk seals have been found with large amounts of plastic in their habitats, including areas where they nurse their young.
Overall, plastic waste ingestion by marine animals has severe consequences, including injury, starvation, and the accumulation of toxic chemicals in their bodies. It is essential to address this issue through proper waste management, recycling, and reducing plastic use to protect marine life and the health of our oceans.

Plastic pollution affects marine ecosystems
One of the main ways plastic pollution harms marine ecosystems is by entangling marine animals. Plastic waste can easily trap animals, preventing them from eating or swimming, or even causing them to drown. This includes endangered wildlife such as Hawaiian monk seals and Pacific loggerhead sea turtles. It is estimated that entanglement and ingestion of plastic impact 914 megafaunal species, with more than 100 of them endangered.
Another significant impact is the ingestion of plastic by marine animals, mistaking it for food. Research indicates that half of the sea turtles worldwide have ingested plastic, which can lead to starvation as it reduces the storage volume of their stomachs. Plastic ingestion has also been found to affect the reproduction rates of sea turtles by altering the temperature of the sand where incubation occurs. Furthermore, plastic pollution can act as a vector for toxic chemicals, which can have detrimental effects on marine life. These chemicals can disrupt the endocrine systems of humans and other animals, posing a threat to wildlife and ecosystems.
Plastic pollution also disrupts the delicate balance of marine ecosystems. Floating plastic debris can allow some species to spread beyond their natural habitats, leading to their proliferation in new environments and upsetting the natural balance. This can have detrimental consequences for the native marine life in these areas.
The durability of plastic means that once it enters the ocean, it persists for long periods, continuously harming marine life. Plastic pollution has been found to date back to the 1960s, highlighting its longevity in the marine environment. The widespread use of plastic and improper waste management contribute to the growing crisis, with an estimated 8 million tonnes of plastic ending up in the ocean each year.

Plastic pollution impacts human health
Plastic pollution is a pressing issue that affects not only the environment but also human health and well-being. The pervasive nature of plastic pollution means that it is found in various ecosystems, including our oceans, soil, and even the air we breathe. As a result, humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact. These toxic chemicals have been linked to adverse health effects, including endocrine disruption, weight gain, insulin resistance, and reproductive issues.
One of the primary ways plastic pollution impacts human health is through the ingestion of contaminated seafood. Fish and other marine organisms often mistake plastic waste for food, and when we consume these fish, we ingest the toxins they have accumulated. Additionally, microplastics have been detected in tap water, bottled water, and even commonly consumed beverages like beer. These microplastics can also originate from the plastic bottles and containers we use for these beverages.
The production and disposal of plastics also contribute to air and water pollution, further exacerbating the health impacts on humans. The extraction of crude oil, the primary raw material for plastics, often involves drilling and fracking, which can contaminate groundwater and damage ecosystems. The refining and manufacturing processes release harmful chemicals and industrial waste into the environment, leading to air and water pollution.
Vulnerable groups, including children, pregnant women, and marginalized communities, are particularly susceptible to the health risks associated with plastic pollution. Exposure to toxic chemicals during critical stages of development can lead to birth defects, neurodevelopmental impairments, impaired lung growth, and an increased risk of childhood cancer. The pervasive nature of plastic pollution means that it is challenging to avoid exposure, and the accumulation of these toxins in our bodies can have long-term health consequences that are not yet fully understood.
While the specific mechanisms are still being studied, current research indicates that plastic pollution contributes to diseases, disabilities, and premature deaths. The toxic chemical additives used in plastics production have been linked to endocrine disruption, cancer, and reproductive, growth, and cognitive impairments. With the constant presence of plastic pollution in our environment, it is essential to address this issue through reduced plastic usage, improved waste management, and the development of sustainable alternatives.

Plastic waste is a global issue
Plastic is made from fossil fuels like gas and petroleum, and the process of making it can also harm the environment. The extraction of crude oil, which is used to make plastic, can contaminate groundwater and damage ecosystems. Turning crude oil into plastic also releases harmful chemicals and pollutants into the air and water. So even before plastic becomes waste, it is already causing problems for the environment.
Once plastic waste enters the ocean, it can have serious effects on marine life. Animals such as fish, birds, turtles, seals, and even whales can become entangled in plastic waste, like old fishing nets or plastic rings. They may also mistake plastic for food and eat it, which can make them very sick or even kill them. Plastic can also affect the ocean environment by breaking down into tiny pieces called "microplastics" that are too small to be seen but are still harmful. These microplastics can be eaten by small organisms and then move up the food chain, eventually ending up in the seafood that humans eat.
The good news is that people are working on solutions to this global problem. Organizations like The Ocean Cleanup are trying to clean up the plastic that is already in our oceans and rivers. Other groups are pushing governments and companies to treat plastic pollution as a hazardous form of waste and reduce plastic production. By taking action now, we can help protect ocean life and our environment for the future.

Frequently asked questions
Plastic in the ocean can harm animals in many ways. Animals like birds, fish, turtles, seals, dolphins, whales, and other marine mammals often mistake plastic for food and eat it. Plastic can fill up their stomachs and make them feel full, leading to starvation. Plastic can also release harmful chemicals that can build up inside the bodies of animals and people, causing health issues. Plastic can trap and entangle animals, preventing them from moving, eating, or swimming, and sometimes even causing them to drown.
Plastic enters the ocean from many sources and places around the world. When plastic is not recycled, incinerated, or put in landfills, it can become an environmental pollutant and find its way into oceans through rivers and waterways. Plastic waste is often mismanaged, and less than 0.5% of all the plastic produced each year ends up in the ocean, which is still a huge amount—over a million metric tons!
Plastic in the ocean can have severe consequences for marine life. Plastic does not go away on its own and can last for hundreds of years. Over time, it breaks down into smaller pieces called microplastics, which are so tiny that they cannot be seen, but they are still harmful. These microplastics can be eaten by small organisms and work their way up the food chain, increasing in amount and becoming more toxic.
It is estimated that about 8 million tons of plastic end up in the ocean each year. There are currently 15 to 51 trillion pieces of plastic in the oceans, and this number is expected to grow. Plastic can be found on the surface and deep in the ocean, from the equator to the poles, and even in the stomachs of animals.
