Study says conservation slowing animal extinctions

NEW YORK — On average, 52 species of mammals, birds and amphibians are taking a significant step toward extinction each year, a huge new analysis says.
But if not for conservation efforts, the march would be even faster, researchers reported Tuesday.
Efforts to save endangered animals are making a difference, even as about 1 in 5 of the world's backboned species — mammals, birds, reptiles, amphibians and fish — are threatened with extinction, according to a study published online in the journal Science.
The report was released as delegates from more than 190 nations meet at a United Nations conference in Nagoya, Japan, to set 20 measurable targets to combat the loss of many diverse species.
