The Ocean's Plastic Problem: Understanding Marine Pollution

Plastic pollution is a pressing issue, with an estimated 80% of all marine pollution being plastic waste. While it is difficult to determine the exact amount of plastic in the ocean, scientists believe that around 8 million metric tons of plastic entered the ocean in 2010. This is the equivalent of nearly 90 aircraft carriers. More recent estimates place the figure at between 1 million and 1.7 million tons per year, while previous studies have suggested a figure of 1 million tons. This plastic waste comes from littering, improper manufacturing processes, and industrial fishing.

Plastic waste makes up 80% of marine pollution

Rich countries produce the most plastic waste per person, but the mismanagement of waste is more important for plastic pollution. Mismanagement means that waste is not recycled, incinerated, or kept in secure landfills, and is therefore 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.

Early studies estimated that ocean plastics could be around 8 million tonnes per year, but more recent research with improved methods estimates that this figure is somewhere between 1 million and 1.7 million tonnes. This means that around 0.5% of the world's plastic waste ends up in the oceans. However, the fate of plastics once they enter the ocean has been something of a puzzle for researchers, as the amount of plastic floating on the surface offshore is significantly less.

In addition to littering, about 20% of the ocean's plastic pollution comes from industrial fishing and improper manufacturing processes. This includes microplastics, which are tiny plastic particles that can be harmful to marine life and the environment. The presence of plastic in the ocean is a significant issue, and it is important to address it through proper waste disposal, recycling, and other measures to reduce plastic pollution.

Plastic waste is caused by littering and improper manufacturing processes

Littering is the main cause of plastic pollution in the ocean. We buy or use disposable plastic items (such as food wrappings, plastic bags, razors, and bottles) and do not dispose of them properly. This causes them to end up in waterways and eventually in the ocean. Nearly one-quarter of the world's plastic waste is mismanaged or littered. This means it is not stored in secure landfills, recycled, or incinerated. One-quarter of that (around 19 million tons) is leaked into the environment. Rich countries produce the most plastic waste per person, but the mismanagement of waste is more common in low-to-middle-income countries due to poorer waste management infrastructure.

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. Plastic waste makes up 80% of all marine pollution.

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. Mismanagement means that waste is not recycled, incinerated, or kept in secure landfills, and is therefore 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.

The fate of plastics once they enter the ocean has been a puzzle for researchers. While at least one million tons of plastic enters the ocean each year, the amount of plastic floating on the surface offshore is significantly less. This suggests that much of the plastic is sinking or being ingested by marine life, with potentially devastating consequences for the environment.
