McCann Portugal created this anti-global-warming spot on behalf of Quercus, the country's national nature-conservation association. The animation is nice and bleak, the piano music plaintive. But the science seems dodgy—will animals really start committing suicide en masse if global warming gets worse? (The tagline is, "If you give up, they give up.") If post-apocalytpic movies have taught us anything, it's that human folly usually brings great opportunities for wily non-humans.
