And Here I Was Getting Upset About Obama Following Bush Policy In Pending Court Cases....

When I should have been more alarmed about the news that we are close to destroying the Ph balance of the oceans as an offshoot of global warming!

Since 1800, humans have generated 240 billion tonnes of carbon dioxide, half of which has been absorbed by the sea. On average, each person on Earth contributes a tonne of carbon to the oceans every year. The result is a rapid rise in acidity — or a reduction in pH, as the scientists prefer to express it — which, as it intensifies, will mean that marine animals will be unable to grow shells, and that many sea plants will not survive. With these crucial links removed, and the ecological balance fatally disrupted, death could flow all the way up the food chain, through tuna and cod to marine mammals and Homo sapiens. As more than half the world’s population depends on food from the sea for its survival, this is no exaggeration.
