Scientists blame ocean dead zones on climate change

Peering into the murky depths, Jane Lubchenco searched for sea life, but all she saw were signs of death.

Video images scanned from the seafloor revealed a boneyard of crab skeletons, dead fish and other marine life smothered under a white mat of bacteria. At times, the camera's unblinking eye revealed nothing - a barren undersea desert in waters renowned for their bounty of Dungeness crabs and fat rockfish.

"We couldn't believe our eyes," Lubchenco said, recalling her initial impression of the carnage brought about by oxygen-starved waters. "It was so overwhelming and depressing. It appeared that everything that couldn't swim or scuttle away had died."

Rethinking the Meat-Guzzler

Livestock production generates nearly a fifth of the world’s greenhouse gases — more than transportation. If Americans were to reduce meat consumption by just 20% it would be as if we all switched from a standard sedan — a Camry, say — to an ultra-efficient Prius.

[...]

A sea change in the consumption of a resource that Americans take for granted may be in store — something cheap, plentiful, widely enjoyed and a part of daily life. And it isn’t oil.

It’s meat.

The two commodities share a great deal: Like oil, meat is subsidized by the federal government. Like oil, meat is subject to accelerating demand as nations become wealthier, and this, in turn, sends prices higher. Finally — like oil — meat is something people are encouraged to consume less of, as the toll exacted by industrial production increases, and becomes increasingly visible.

Hair and mushrooms create a recipe for cleaning up oily beaches

A group of guerrilla volunteers is cleaning oil from San Francisco's beaches using an unorthodox, albeit totally organic, method: human hair and mushrooms.

Using mats made of hair, they are absorbing the droplets of oil that have washed ashore since a cargo ship rammed the base of a Bay Bridge tower last week, spilling 58,000 gallons of fuel.

Hair, which naturally absorbs oil from air and water, acts as a perfect sponge, said Lisa Gautier of San Francisco, who provided 1,000 hair mats. They are about the size of a doormat, tightly woven with dark hair, and feel somewhat like an S.O.S pad.

While the mats may not be the obvious choice among hazardous waste experts, they hit San Francisco's green chord: More than 700 volunteers have tried them in recent days. Organizers hope their success will inspire more ecological responses to toxic waste removal.

US Emits 8.2 Tons of CO2 per person

A study of the world's power stations has shown the extent to which developed countries produce more carbon dioxide per head than emerging economies.

Australians were found to be the world's worst polluters per capita, producing five times as much CO2 from generating power as China.

The US came second with eight tonnes of the greenhouse gas per head - 16 times more than that produced by India.

The US also produced the most CO2 in total, followed by China.

The Carbon Monitoring for Action (Carma) website is the first global inventory of emissions and looks at 50,000 power stations.

Its data was compiled by the Center for Global Development, a US think-tank.
