Unhappy Endangered Species List Expands to 16,000

I was surprised when I saw this recent list that hippos and polar bears are threatned with extinction. The report below is from the National geographic website:

In the recently released update of its Red List of Threatened Species, the World Conservation Union (IUCN) says that more than 40 percent of species that have been assessed worldwide are threatened with extinction.

These include a quarter of the world's coniferous trees, an eighth of its birds, and one-third of its amphibians.

For the first time, polar bears and hippopotamuses are now designated as threatened.

Polar bears, the IUCN said, are likely to become one of the most notable casualties of global warming, which is melting sea ice on which they roam in search of Arctic seals.

Without enough ice, the bears risk being trapped on land, where they face starvation. Or they may drown in attempts to swim long distances.

Earlier this year, the U.S. Fish and Wildlife Service announced that it is considering adding polar bears to the U.S. endangered species list.

Although the decline in polar bear numbers is expected to be relatively slow, other animal populations have already crashed dramatically.

The hippopotamus, for example, has declined by 95 percent in the Democratic Republic of the Congo since 1994, when 30,000 roamed wild.

Never before listed by the IUCN, hippos are now classified as "vulnerable" mainly because of unregulated hunting in the war-torn country.

Farther north in Africa, the dama gazelle of the Sahara region has suffered an 80 percent decline in the past decade because of uncontrolled hunting.

Nor are land animals the only ones experiencing such declines. Among sea creatures, the IUCN took a close look at sharks and rays, finding that one-fifth of the 547 species it assessed are threatened with extinction, probably due to overfishing.

"Marine species are proving to be just as much at risk of extinction as their land-based counterparts," said Craig Hilton-Taylor of the IUCN Red List Unit in a statement.

The Red List is the best worldwide system for ranking endangered species, even though it conveys no direct protection to any of the listed species, said Kieran Suckling, policy director for the Center for Biological Diversity, in Tucson, Arizona.

Other ranking systems, he said, are subject to political pressures that can skew the results.

"Here you have an unbiased, objective account," he said. "There's no guesswork and no political pressure. … The listings tend to focus conservation energy."

The Red List now contains 40,177 species, 16,119 of which are categorized as critically endangered, endangered, or vulnerable.

Large as those numbers are, they represent only a fraction of the world's species, estimated to total somewhere between 10 million and 100 million.
