Global Warming - Conservative Policy?

I believe that pollution and waste should be controlled if it can be solidly proven by several non-partisan and validated sources that it has a detrimentally negative effect on the surrounding area. Global warming is a scam, but that doesn't mean I think factories should dump toxic sludge in a local lake, or be allowed to pump out tons of hazardous gasses into the atmosphere. It's all a balancing act. If their pollution is affecting the immediate area, then intervention is needed, if not, then let them be.
