350 is the parts per million of carbon dioxide in the air, above which scientists say our environment is no longer sustainable.

Currently, the global measurement is at 390 parts per million.

On 10/10/2010, 350.org is calling on people of the world to form work parties to do something constructive to slow global warming.  Why not window farms?  Go to the site, and register a window farm build group in your area!
