Wolves off the Endangered List

In a good news story about conservation, the gray wolf population of the northern Rocky Mountains in the U.S. has gone from nearly zero to about 1,500 over the last 13 years. This population is now being delisted from the federal Endangered Species List. Cheering the move are state governments which want more freedom to kill livestock predators, while environmental groups insist the action is premature and will lead to a repeat of the widespread killing that put the wolves on the list in the first place.
