Eight million metric tons of plastic waste enter the oceans every year. Every day, thousands of tonnes of plastic waste are entering the ocean.This waste kills marine wildlife and enters our food supply via seafood and salt.On this page we’ve listed some of the most shocking facts and statistics about plastic in the ocean.Before we start, here’s a quick caveat about these facts and statistics:It’s impossible to know exactly how much plastic is in the ocean and how much enters it each year.Similarly, the data we have on plastic contamination in marine wildlife is usually based on extrapolating the results of quite small studies across whole populations.On this page we’ve tried to give straightforward answers to lots of the questions people have about plastic pollution in the oceans, but it’s important to say that these figures are often only estimates.We’ve included links to the sources of each statistic so you can look into the details of each yourself.In 2015 it was estimated that the ocean contained at least 150 million metric tonnes of plastic.Based on estimates of how much plastic is entering the ocean each year, it’s likely that the ocean contains over 180 million metric tonnes of plastic in 2019.It’s estimated that around 8 million metric tonnes of plastic enter the ocean each year.To put this into context, this is the same weight as about 630,000 London buses.Estimates of how much plastic enters the ocean each year vary greatly from less than 5 million tonnes to over 14 million, but the 8 million figure is the one given most frequently.In 2014 it was estimated that the oceans contained 15 to 51 trillion particles of microplastics, weighing between 93 and 236 thousand metric tonnes.According to the UN, around 300 million tonnes of plastic waste is produced each year globally.According to the UN, about 9% of plastic produced globally gets recycled.If 300 million metric tonnes of plastic waste are produced each year and 8 million metric tonnes end up in the ocean, this would mean that about 2.67% of plastic waste ends up in the ocean.This figure could be quite inaccurate, as it depends on two estimates (the amount of plastic produced and the amount that enters the ocean). How does plastic end up in the ocean? The ocean plastics problem didn’t begin until plastics went mainstream — and before they could do that, they had to be invented. In this way, the plastic is transported from high-density areas to low-density areas. Because of the convergent nature of this Ekman flow, densities tend to be high in Transitional Water. 1976; Nagata et al. The plastic debris sampled is determined by net mesh size, with similar mesh sizes required to make meaningful comparisons among studies. In 1869, John Wesley Hyatt created the first synthetic plastic by combining a cellulose derived from cotton with the waxy solid camphor to form celluloid. One proposed ‘sink’ for ocean plastics was deep-sea sediments; a study which sampled deep-sea sediments across several basins found that microplastic was up to four orders of magnitude more abundant (per unit volume) in deep-sea sediments from the Atlantic Ocean, Mediterranean Sea and Indian Ocean than in plastic-polluted surface waters. The focus on this expedition was surveying the extent of tsunami debris from the Japanese earthquake-tsunami.In 2012, researchers Goldstein, Rosenberg and Cheng found that microplastic concentrations in the gyre had increased by two On 9 September 2018, the first collection system was deployed to the gyre to begin the collection task.In June 2019, Ocean Voyages Institute, the same organization behind the 2009, 2010 & 2012 expeditions, conducted a cleanup in the gyre and removed over 84,000 pounds of polymer nets and consumer plastic trash from the ocean.In May/June 2020, Ocean Voyages Institute conducted a cleanup expedition in the Gyre which removed over 103 tons (206,000 pounds) of consumer plastics and ghostnets from the oceanAccording to National Geographic, "About 54 percent of the debris in the Great Pacific Garbage Patch comes from land-based activities in North America and Asia. 1986). L.J. Some ways in which plastic enters the ocean include: Plastic items are lost from ships and boats; Plastic items are blown into the sea The name "Pacific Garbage Patch" has led many to believe that this area is a large and continuous patch of easily visible marine debris items such as bottles and other litter – akin to a literal island of trash that should be visible with satellite or aerial photographs. The Research indicates that the patch is rapidly accumulating.The patch was described in a 1988 paper published by the In 2010, Ocean Voyages Institute conducted a 30-day expedition in the gyre which continued the science from the 2009 expeditions and tested prototype cleanup devices.in July & Aug 2012 Ocean Voyages Institute conducted a voyage from San Francisco to the Eastern limits of the North Pacific Gyre north, (ultimately ending in Richmond British Columbia) and then made a return voyage which also visited the Gyre.
