Oceans of Plastic Trash: A Cleanup Plan

A growing volume of plastic waste is killing off ocean life across the world. Fish, sea mammals, seabirds and many other forms of marine life are all threatened. A team of American and Australian researchers estimates that about eight million metric tons of plastic waste ended up in oceans during 2010 alone. Five countries in Asia are the biggest sources of the waste: China, Indonesia, the Philippines, Vietnam and Sri Lanka.
