Way, way, way back in 1990, the NRDC put out this public service announcement featuring Tom Cruise, Whoopie Goldberg, Demi Moore, Billy Crystal and Warren Beatty discussing the effects of pollution and global warming. Now that the rest of the world is beginning to catch on to the issues we face as a planet, it's nice to know those celebs we all look up to really are ahead of the curve. (At least on this one thing.) Anyways... nothing you don't know here... just scary it's almost 20 years old.
