We are the only species capable of saving the earth from the next big asteroid. Instead, we are creating conditions that will have the same effect in the near future.

ScienceDaily (Oct. 6, 2008) — The most comprehensive assessment of the world’s mammals has confirmed an extinction crisis, with almost one in four at risk of disappearing forever, according to The IUCN Red List of Threatened Species™, revealed at the IUCN World Conservation Congress in Barcelona.
The new study to assess the world’s mammals shows at least 1,141 of the 5,487 mammals on Earth are known to be threatened with extinction. At least 76 mammals have become extinct since 1500. But the results also show conservation can bring species back from the brink of extinction, with five percent of currently threatened mammals showing signs of recovery in the wild.
“Within our lifetime hundreds of species could be lost as a result of our own actions, a frightening sign of what is happening to the ecosystems where they live,” says Julia Marton-Lefèvre, IUCN Director General. “We must now set clear targets for the future to reverse this trend to ensure that our enduring legacy is not to wipe out many of our closest relatives.”
The real situation could be much worse as 836 mammals are listed as Data Deficient. With better information more species may well prove to be in danger of extinction.
“The reality is that the number of threatened mammals could be as high as 36 percent,” says Jan Schipper, of Conservation International and lead author in a forthcoming article in Science.
