How to Save the Oceans

The oceans of studies on dying seas have done nothing to stop their devastation. In a 2011 report, the Oxford-based International Program on the State of the Ocean wrote that the planet faced “losing marine species and entire marine ecosystems, such as coral reefs, within a single generation.” Last month, the United Nations Intergovernmental Panel on Climate Change reported that the effects of human-induced climate change are already far-reaching. It also singled out ocean acidification. As the oceans absorb higher levels of carbon, the more acidic water threatens coral reefs, shellfish, and other marine life.

The experts only confirm what people around the world see every day: marshland, once teeming with wildlife, paved over; subsistence fishermen in poor countries driven from the ocean by industrial fishing; recreational fishermen chasing fewer and smaller fish farther out to sea; surfers getting hepatitis shots before entering sewage-contaminated waters; families on vacation snorkeling through coral bone-yards. In the Chesapeake Bay, the United States’ largest estuary, harvests of native oysters have fallen to less than one percent of historic levels due to the combined effects of overfishing, disease, and habitat destruction.

There is no shortage of international recommendations, action plans, and other prescriptions for restoring the oceans’ health. The 1982 United Nations Convention on the Law of the Sea, the 1992 Rio Earth Summit, the 2002 Johannesburg World Summit on Sustainable Development, and the 2012 United Nations Conference on Sustainable Development (Rio+20) all put forward different ways to protect the oceans from pollution and overfishing, preserve biological diversity, and help
