Meet Rodney Jackson, one of the world's leading snow leopard biologists and conservationists and director of the Snow Leopard Conservancy.

Negative attitudes toward wolves enabled a centuries-long extermination campaign that nearly wiped out the gray wolf in the continental United States by 1950.

Lion conservationists are enlisting every ally they can find. In early 2006, for instance, two groups held a "lion summit" in Johannesburg, South Africa.

In hopes of protecting both lions and farmers, local communities have embarked on a model experiment in wildlife-friendly land management called the Laikipia Predator Project.
