When John J. Audubon visited the Florida Keys, reddish egrets were abundant. Now, the heron-relative is on Audubon's Red Watchlist and is being further threatened by the oil spill.

A Google Earth engineer is helping us relate to the magnitude of the oil spill through a map overlay function. See how much of your hometown (or state) would be covered by the growing oil slick.

When booms are bust and weather doesn't permit setting the oil aflame, what are the options? Dispersants have proved effective, but environmentalists are concerned with potentially toxic side effects for marine life.

An extreme winter has already left 3.4 Mongolian animals dead and is continuing to claim many more. Both livestock and herders alike are facing starvation and death.

Researchers have found that whale poop could ease global warming and carbon dioxide levels. This, however, is not the first time poop has been used for good. Check out some ways the stinky stuff has been reconfigured for function from flooring to facials.

 
A zoo in Britain just received a sheepishly-looking breed of oinker, the Mangalitza. Since then, the pigs in a blanket have been the subject of curious visitors and have been spotted at celebrity movie premieres. Pet pigs and celebrities, however, have a longer history than one might think.
