(From parade.com)- As director of The Marine Mammal Center in Sausalito, Calif., Frances Gulland sees firsthand the effects of the oceans’ deteriorating state. Her patients have included cancer-stricken sea lions whose tumors are thought to be associated with PCBs, sea otters infected by a parasite linked to run-off, and fur seals sickened by toxic algae. Lack of public attention may be due to the sea’s placid appearance. “You look at the surface, and it looks fine,” says Prof. Jane Lubchenco of Oregon State University in Corvallis. “Yet below the surface is a whole different story.”
A recent study led by the National Center for Ecological Analysis and Synthesis in Santa Barbara, Calif., found that close to half of the oceans are “fairly degraded,” and only 3.7% show little or no impact from human activity. Oceans help keep the environment healthy by absorbing carbon dioxide. But now the results of that intake are evident. The seas have risen, warmed, and acidified worldwide. Those changes, combined with overfishing, have caused 90% of our big fish to disappear, according to Leon Panetta, co-chair of the Joint Ocean Commission Initiative. “Pollution has led to almost 26,000 U.S. beaches being temporarily closed or put under advisories,” he adds, “ and nearly 90% of our wetlands, the nurseries for fish, have vanished due to development. The oceans are in crisis.”
The U.S. government spends relatively little on the sea. Around $18,700 per square mile goes to the National Park System, while $400 per square mile goes to its ocean counterpart, the National Marine Sanctuary System. Private charities show a similar trend. “Close to 99% of conservation dollars donated go to land causes, and 1% to oceans,” says Debra Erickson, executive director of the nonprofit Kerzner Marine Foundation (KMF). “But over 70% of the Earth is covered by oceans.”
