"A growing number of creatures could disappear from the earth, with one-fifth of all vertebrates and as many as a third of all sharks and rays now facing the threat of extinction, according to a new survey assessing nearly 26,000 species across the globe.
In addition, forces such as habitat destruction, over-exploitation and invasive competitors move 52 species a category closer to extinction each year, according to the research, published online Tuesday by the journal Science. At the same time, the findings demonstrate that these losses would be at least 20 percent higher without conservation efforts now underway."
