Discarded plastic is a major problem in today’s oceans. Plastics leach toxic chemicals into the seawater while otherwise not degrading. Recently researchers at Harvard University have announced they have created a new bio-degrable plastic based on, of all things, shrimp shells.
We have posted for several years now about the vast floating collection of trash in the Pacific Ocean. It goes by a variety of names including the plastic vortex and the great Pacific garbage patch. It is held together by the circular current, the North Pacific Gyre. Similar garbage patches have formed in the Atlantic and Indian Oceans. The floating plastic is often deadly to sea birds, fish and whales which inject the trash. Once tossed in the oceans, the plastic simply does not go away.
