"One in five of the world's 380,000 plant species is threatened with extinction and human activity is doing most of the damage, according to a global study published on Wednesday."

Asian stink bugs have invaded the East Coast, are spreading, and are getting into people's yards and houses. When disturbed, they emit an unpleasant smell.

"We've always played with our food — even before we knew about genes or how to change them. ... Now comes an Atlantic salmon that is genetically engineered to grow twice as fast as a regular salmon. If U.S. regulators approve it, the fish would be the first such scientifically altered animal to reach the dinner plate. Scientists have already determined that it's safe to eat. They are weighing other factors, including environmental risks, after two days of intense hearings."

"A number of the playful marine mammals are being poisoned by an ancient microbe that appears to be on an upsurge in warmer, polluted waters around the world."

"While a genetically engineered salmon is almost certainly safe to eat, the government should pursue a more rigorous analysis of the fish's possible health effects and environmental impact, members of a federal advisory committee said yesterday."

"The first genetically modified animal could move one step closer to the U.S. market on Monday, when a federal advisory panel makes its recommendation on whether such food -- a salmon -- is safe for consumers to eat."
