On Wednesday, the polar bear Gus and Ida at the Central Park Zoo held a press conference, with some help from the Natural Resources Defense Council. The point was to announce that the Center for Biological Diversity and Greenpeace would take legal action against the government for further endangering the already-endangered polar bears: Global warming is leading to polar bears' natural habitats to melt out. And the press conference's location was to drive home the fact that zoos may be the only place where you can see polar bears if things keep going as they have. We love the idea that polar bears would hold a press conference, concerned about their wild relatives, and in fact, we hope the NRDC can get the penguins to give a press conference next.
