Plastic Waste

Every minute, two garbage trucks of plastic are dumped into our oceans. Currently, 300 million metric tons of plastic winds up in the oceans. The amount of plastic trash that flows into the oceans every year is expected to nearly triple by 2040 to 29 million metric tons.

Microplastics in different forms are present in almost all water systems in the world, be they streams, rivers, lakes, or oceans. There is more microplastic in the ocean than there are stars in the Milky Way.

There are five massive patches of plastic in the oceans around the world. These huge concentrations of plastic debris cover large swaths of the ocean. One patch in particular, known as the “Great North Pacific Garbage Patch” covers 1.6 million square kilometers of water.

By 2050 there will be more plastic in the oceans than there are fish (by weight).

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.

Plastic has been found at 36,000 feet (approximately 11km) in the Mariana Trench, meaning not even the deepest part of the world’s oceans can escape contamination.

Over 1 million marine organisms are killed each year due to plastic pollution in the ocean. Animals who eat plastic often starve because the plastic prevents them from properly swallowing food.

The chances of disease on a coral reef are enhanced by 22-fold by plastics. In 2018, a huge survey of the 159 coral reefs across Asia-Pacific region showed that over 11.1 billion plastic particles are entangling the corals, and this number is estimated to increase dramatically by 40% by 2025. Plastic debris may also cause physical damage to the corals by exhausting the resources for the wound-healing process. Importantly, more than 7000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals can be found in the coral reef ecosystem.

Animals are now colonizing the Great Pacific Garbage Patch, meaning that they are consuming the plastic waste and also living in previously uninhabited areas. All of these developments disrupt the natural marine ecosystem.Many animals at the base of the food chain eat microplastics. These animals are then consumed by others than humans eat.

The chart shows the increase of global plastic production, measured in tonnes per year, from 1950 onwards.

In 1950 the world produced only 2 million tonnes per year. Since then, annual production has increased nearly 230-fold, reaching 460 million tonnes in 2019.

The short downturn in annual production in 2009 and 2010 was predominantly the result of the 2008 global financial crisis — a similar dent is seen across several metrics of resource production and consumption, including energy.
