Should kids be exposed to more or less toxic pollution?

The limits of my knowledge about what's really going on in the world continue to amaze me. A case in point is the fact that major polluters, such as power plants, cement kilns and other industrial plants, have never been effectively forced to reduce the toxic emissions they put into the air. The EPA has proposed stringent new rules to finally clean up polluters, through existing and affordable technology that would vastly improve the health of millions of Americans, but the GOP is going all out to weaken the proposed regulations.
