"This week a major conference in Cairns, Australia, is focusing on threats to coral reefs. Across the globe, reefs have been savaged by rising sea temperatures, overfishing, pollution and ocean acidification – a phenomenon related to rising carbon dioxide levels in the atmosphere that make it difficult for creatures to build their shells and skeletons."

"LOS ANGELES -- White abalone, the endangered shellfish that once numbered in the millions off the Southern California coast, have declined precipitously over the last decade and are on the brink of extinction, a study has found."

"Perhaps you heard the story going around today. A genetically modified grass started pumping out cyanide gas, killing a herd of cattle. CBS News had the scoop, as seen at WTVR.com in Richmond: 'Genetically modified grass linked to cattle deaths.' It’s basically a story custom-built for rapid spread around the internet. And it is basically completely wrong. The grass at issue, Tifton 85, was not genetically modified at all, but rather is a hybrid."

"Lonesome George, the last remaining tortoise of his kind and a conservation icon, died on Sunday of unknown causes, the Galapagos National Park said. He was thought to be about 100 years old."
