The state of our oceans, in a clamshell

Our oceans, long taken for granted, are being stressed by pollution, over-fishing and climate change. Plastic gyres, swirling pools of plastic refuse, occupy several spots in the Pacific and Atlantic oceans. The largest one, in the North Pacific, is estimated to exceed the size of Texas….These linked, but disparate problems — pollution, unsustainable fishing practices, jobs at risk — won’t be solved easily. That’s why several environmental and conservation groups working around the globe have formed the Global Partnership for Oceans. The groups hope that together they can work to save the marine environment before human pressures cause natural fisheries to collapse.
