The trade in plastic waste from industrialized countries to developing countries has been identified as the main cause of marine litter because countries importing the waste plastics often lack the capacity to process all the material. [249] Therefore, the United Nations has imposed a ban on waste plastic trade unless it meets certain criteria.
Around 275 million tonnes of plastic waste is generated each year around the world; between 4.8 million and 12.7 million tonnes is dumped into the sea. [6] About 60% of the plastic waste in the ocean comes from the top five countries: China, Indonesia, the Philippines, Thailand and Vietnam. [71]
The 2011 edition of the United Nations Environment Programme Year Book identifies as the main emerging environmental issues the loss to the oceans of massive amounts of phosphorus, "a valuable fertilizer needed to feed a growing global population", and the impact billions of pieces of plastic waste are having globally on the health of marine ...
Fish may rule the oceans now, but, according to a World Economic Forum report released on Tuesday, that may not be the case for long. Report: Ocean's plastic waste will outweigh fish by 2050 Skip ...
Having collected over 100 tonnes of plastic waste to date, the social enterprise is doing its bit to address a local problem that has global ramifications. In major ocean polluter Philippines ...
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
