Google Pollution Maps of China

A blogger out of Fujian has compiled an open-source google map that places major pollution sites around china. While similar sources have existed in the past, this is the first one that allows other users to contribute sites with pollution problems. The map, which was created by Guo Baofeng, has attracted a lot of interest on Chinese BBS' and Forums: check it out while you still can, because you never know when it could suddenly disappear.
