A prediction that the world s oceans will contain more plastic than fish by 2050 is likely to intensify the push for sustainable, environmentally friendly alternatives.
Plastics marked as biodegradable do not degrade rapidly in the ocean, says the report, published Monday.
The 179-page report on plastic marine debris is one of several documents released in time for the United Nations Environment Assembly, which kicked off Monday in Nairobi, Kenya.
Plastics, which can cause serious ecological harm, are now ubiquitous in the ocean, found in every ocean and on every shoreline from the Arctic through the tropics to the Antarctic, the report states.
Biodegradable plastics — which have been used for shopping bags, water bottles and food containers — are designed to be less durable and capable of degrading quickly in the environment.
The U.N. estimates that global plastic production grew 4 percent from 2013 to 2014, exceeding 311 million metric tons.
