Last year brought some rare good conservation news: The International Union for Conservation of Nature (IUCN), the folks who determine which species are endangered and which aren't, bumped pandas from endangered to vulnerable. That's a sign that conservation efforts have begun to reverse the effects of the human activity that wiped out the original bamboo-filled panda habitats in the first place. It also makes sense I guess, because science journalists spent all of last year talking about pandas screwing.
