Plastic pollution is a pressing issue for the world's oceans, with an estimated 75 to 199 million tons of plastic waste currently in the oceans, and a further 33 billion pounds of plastic entering the marine environment every year. Plastic waste makes up 80% of all marine pollution, and around 8 to 10 million metric tons of plastic end up in the ocean each year. The Great Pacific Garbage Patch, for example, is made up of all kinds of marine debris and contains 1.8 trillion pieces of plastic, covering an area twice the size of Texas.

The Great Pacific Garbage Patch
Plastic waste makes up 80% of all marine pollution and around 8 to 10 million metric tons of plastic end up in the ocean each year. Previous estimates have been as high as 12 million tons per year. The majority of plastic pollution in the ocean is caused by littering, with disposable plastic items such as food wrappings, plastic bags, razors, and bottles ending up in waterways and eventually in the ocean. However, not all plastic waste in the ocean is a result of littering. Many plastics and microplastics are the product of improper manufacturing processes, and about 20% of the ocean's plastic pollution comes from industrial fishing.
One of the most famous examples of plastic pollution in the ocean is the Great Pacific Garbage Patch. This collection of marine debris contains 1.8 trillion pieces of plastic, covering an area twice the size of Texas. The Great Pacific Garbage Patch is a stark reminder of the impact of plastic pollution on the ocean. It is a floating mass of plastic waste and other debris that has accumulated in the North Pacific Ocean due to the convergence of ocean currents. The patch is not a solid mass but rather a collection of tiny plastic particles, known as microplastics, and larger pieces of plastic debris. The microplastics in the patch are a particular concern as they can be ingested by marine life, leading to health issues and even death. The larger pieces of plastic can entangle and injure marine animals, as well as smother coral reefs and other marine habitats.
The impact of the Great Pacific Garbage Patch extends beyond the ocean. As plastic breaks down into smaller pieces, it can be ingested by marine life, leading to health issues and even death. These plastics can then enter the food chain, potentially impacting human health as well. Additionally, the presence of microplastics in the ocean can disrupt the marine food web, affecting the health of marine ecosystems.
Addressing the issue of plastic pollution in the ocean, including the Great Pacific Garbage Patch, requires a multifaceted approach. This includes improving waste management practices, particularly in low-to-middle-income countries, reducing plastic consumption, and promoting sustainable alternatives to plastic. Additionally, raising awareness about the impact of plastic pollution and supporting initiatives to remove plastic waste from the ocean can help mitigate the problem.

Plastic waste from littering
The majority of plastic pollution in the ocean is caused by littering, but not all plastic waste in the ocean is a direct result of littering. Many plastics and microplastics are the product of improper manufacturing processes, and about 20% of the ocean's plastic pollution comes from industrial fishing. Plastic waste makes up 80% of all marine pollution, and around 8 to 10 million metric tons of plastic end up in the ocean each year. Previous studies have found similar results, suggesting that around 1 million tonnes of plastic ends up in the ocean each year, with earlier estimates as high as 8 million tonnes.
The Great Pacific Garbage Patch is a famous example of ocean pollution, containing 1.8 trillion pieces of plastic and covering an area twice the size of Texas. Plastic is a relatively new invention, appearing in the early 20th century. Since then, the production of plastic has grown exponentially from 2 million tonnes per year in 1950 to 460 million metric tons in 2019. That's a combined 9.5 billion metric tons of plastic from 1950 to 2019, of which approximately 7 billion metric tons has already become waste.
There is an estimated 75 to 199 million tons of plastic waste currently in our oceans, with a further 33 billion pounds of plastic entering the marine environment every year. Rich countries tend to produce the most plastic waste per person, but what's most important for plastic pollution is how much of this waste is mismanaged. Mismanagement means it's at risk of leaking into the environment, and mismanaged waste tends to be much higher in low-to-middle-income countries due to poorer waste management infrastructure.
Plastic pollution is causing catastrophic harm to marine ecosystems, with 100,000 marine mammals and turtles and 1 million sea birds killed by marine plastic pollution every year.

Plastic waste from industrial fishing
Plastic waste makes up 80% of all marine pollution. Around 8 to 10 million metric tons of plastic end up in the ocean each year, with earlier estimates as high as 12 million tons. 20% of the ocean's plastic pollution comes from industrial fishing, with 1.75 tons being chucked into the sea directly from the fishing and shipping industry.
The majority of plastic pollution in the ocean is caused by littering. We buy or use disposable plastic items (food wrappings, plastic bags, razors, bottles, etc.) and do not dispose of them properly, which causes them to end up in the waterways and eventually in the ocean. However, not all plastic waste in the ocean is an effect of littering: many plastics and microplastics are the product of improper manufacturing processes.
Microplastics, and the damage they cause, are particularly present in marine ecosystems, which have taken the brunt of plastic pollution over the decades. There is an estimated 75 to 199 million tons of plastic waste currently in our oceans, with a further 33 billion pounds of plastic entering the marine environment every single year. One of the most famous examples of ocean pollution is the Great Pacific Garbage Patch, which contains 1.8 trillion pieces of plastic, covering an area twice the size of Texas.
Rich countries tend to produce the most plastic waste per person. However, what's most important for plastic pollution is how much of this waste is mismanaged, meaning it is not recycled, incinerated, or kept in sealed landfills. Mismanagement means it's at risk of leaking into the environment. Mismanaged waste tends to be much higher in low-to-middle-income countries due to poorer waste management infrastructure.

Mismanaged plastic waste
Plastic waste makes up 80% of all marine pollution. Around 8 to 10 million metric tons of plastic end up in the ocean each year, with some estimates reaching 12 million tons. The majority of plastic pollution in the ocean is caused by littering. People buy or use disposable plastic items (food wrappings, plastic bags, razors, bottles, etc.) and do not dispose of them properly, which causes them to end up in the waterways and eventually in the ocean. Rich countries tend to produce the most plastic waste per person. However, what’s most important for plastic pollution is how much of this waste is mismanaged. Mismanaged waste is waste that is not recycled, incinerated, or kept in sealed landfills. Mismanagement means it’s at risk of leaking to the environment. Mismanaged waste tends to be much higher in low-to-middle-income countries. This is because these countries tend to have poorer waste management infrastructure.
