There are too many plastics in the ocean. It’s likely that about 10m tonnes of plastic currently ends up in the oceans each year. In 2010 scientists from the National Center for Ecological Analysis and Synthesis and the University of Georgia in Athens estimated the figure as 8m tonnes, and forecast that to rise to 9.1m tonnes by 2015.
The same study, Published in the Journal of Science in 2015, surveyed 192 coastal countries contributing to ocean plastic waste, and found that Asian nations were 13 of the 20 biggest contributors.
A team of researchers in the United States and Australia led by Jenna Jambeck, an environmental engineer at the University of Georgia, analyzed plastic waste levels in the world’s oceans. They found that China and Indonesia are the top sources of plastic bottles, bags and other rubbish clogging up global sea lanes.
