The world is on the brink of a mass extinction. How can we avoid that?

The world's plant and animal species are going extinct at a rate 1,000 to 10,000 times faster than they did before humans came along. If that continues, we could lose one-third to half of all species by the end of the century. A variety of birds, frogs, fish, mammals — gone.

Those grim statistics come from a big recent study in Science, led by Duke University biologist Stuart Pimm. The paper was the most comprehensive attempt yet to calculate a "death rate" for the world's species — an update on work first begun in 1995.
