Pollution...? Does anyone know what the worst type of pollution (air, water, land, noise) is in the U.S. right now? OR does anyone know any newspapers or statistical sources that are about air pollution (And are somewhat current)? Any info (what pollution is, where is comes from, what its effects are, or ways to prevent it) or any sources that deal with this would be greatly appreciated. Thanks!

The EPA has stated that indoor air is 5 times more polluted than outdoor air. To combat this, I have a state of the art air purifier. Proven to reduce indor air quality issues. 25% 1 Vote
