The Ocean's Trash Crisis: Understanding Marine Pollution's Severity

The ocean is full of plastic waste, with an estimated 75 to 199 million tons of plastic currently in our oceans, and a further 33 billion pounds of plastic entering the marine environment every year. While the exact amount of plastic waste entering the oceans is uncertain, more recent research estimates that at least 1 million tonnes of plastic enters the ocean each year. This plastic waste has a devastating impact on marine life, with 100 million marine animals dying each year from plastic waste alone.

The fate of plastics once they enter the ocean

It is estimated that there are 75 to 199 million tons of plastic waste in our oceans, with a further 33 billion pounds of plastic entering the marine environment every year. This constant flow of plastic production is too much for existing waste management and recycling infrastructure. Plastic pollution is everywhere in the ocean – from microplastics in the food chain to plastic water bottles floating on the surface.

One of the most famous examples of ocean pollution is the Great Pacific Garbage Patch. This 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. Nearly one-quarter of the world's plastic waste is mismanaged or littered, with around 19 million tonnes leaked to the environment. Of this, 13 million tonnes go to terrestrial environments, and 6 million tonnes to rivers or coastlines.

The plastic that enters the ocean can have devastating effects on marine life. Around 100 million marine animals die each year from plastic waste alone. 100,000 marine animals die from getting entangled in plastic yearly, and one in three marine mammal species are found entangled in litter. By 2050, the number of fish will be outnumbered by our dumped plastic.

The Great Pacific Garbage Patch

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. This constant flow of plastic production is simply too much for existing waste management and recycling infrastructure. Plastic pollution permeates every inch of the ocean – from microplastics in the food chain to plastic water bottles floating on the surface.

One of the most famous examples of this is the Great Pacific Garbage Patch. This monolith of ocean pollution 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 is a stark reminder of the impact of plastic pollution on our oceans. It is a floating mass of plastic waste 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, that have broken down from larger pieces of plastic waste. These microplastics can be harmful to marine life, as they can be ingested by fish and other animals, leading to health issues and even death.

Mismanaged or littered plastic waste

It is estimated that there is currently between 75 and 199 million tons of plastic waste in the ocean, with a further 33 billion pounds of plastic entering the marine environment every year. This plastic waste comes from a variety of sources, including mismanaged or littered plastic waste.

Nearly one-quarter of the world's plastic waste is mismanaged or littered, amounting to around 82 million tonnes. This mismanaged waste is not stored in secure landfills, recycled or incinerated. Instead, it ends up in the environment, with 19 million tonnes leaked into terrestrial and aquatic ecosystems. Of this, 1.7 million tonnes are transported to the ocean, with 1.4 million tonnes coming from rivers and 0.3 million tonnes from coastlines.

The fate of plastics once they enter the ocean has puzzled researchers. While at least one million tonnes of plastic enter the ocean each year, the amount of plastic floating on the surface offshore is significantly less. This discrepancy has led to speculation about the fate of the remaining plastic.

The Great Pacific Garbage Patch is a well-known example of ocean pollution, containing 1.8 trillion pieces of plastic and covering an area twice the size of Texas. This accumulation of marine debris is a stark reminder of the impact of plastic waste on the environment.

Plastic waste in the food chain

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. This constant flow of plastic production is simply too much for existing waste management and recycling infrastructure. Plastic pollution permeates every inch of the ocean – from microplastics in the food chain to plastic water bottles floating on the surface.

Microplastics are small plastic particles that are less than five millimetres in length. They are formed when larger pieces of plastic break down or are broken up into smaller pieces. These microplastics can be ingested by marine organisms, which can lead to health issues and even death. They can also be absorbed by marine plants and animals, which can then be consumed by humans.

One of the most famous examples of plastic pollution in the ocean is the Great Pacific Garbage Patch. This monolith of ocean pollution 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 garbage patch is a stark reminder of the impact of plastic pollution on the ocean and the need for better waste management practices.

The impact of plastic waste in the food chain is already being felt. It is estimated that 100 million marine animals die each year from plastic waste alone. Additionally, 100,000 marine animals die from getting entangled in plastic yearly. This is just the creatures that we find and does not account for the many animals that may be impacted but are not discovered. By 2050, it is predicted that the pollution of fish will be outnumbered by our dumped plastic.

Plastic waste on coastlines

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. This constant flow of plastic production is simply too much for existing waste management and recycling infrastructure. Plastic pollution permeates every inch of the ocean – from microplastics in the food chain to plastic water bottles floating on the surface.

The fate of plastics once they enter the ocean has been something of a puzzle for researchers. At least one million tonnes of plastic enters the ocean each year. But the amount of plastic floating on the surface offshore is magnitudes less. Some estimates are in the range of tens to hundreds of thousands of tonnes.

The OECD's Global Plastic Outlook (2022) estimates that around 0.5% of the world's plastic waste ends up in the ocean. Nearly one-quarter of the world's plastic waste is mismanaged or littered. Around 82 million tonnes of plastic waste is mismanaged, of which 19 million tonnes are leaked to the environment. 13 million tonnes go to terrestrial environments, and 6 million tonnes to rivers or coastlines. 1.7 million tonnes of this is then transported to the ocean: 1.4 million tonnes from rivers, and 0.3 million tonnes from coastlines.
