My problem with enviromentalist is that it is usually a cover for anticapitalist. Most of their so called solutions are to make "evil corporations" pay. I put them in the Blame America First crowd.
The biggest cause of pollution is immigration and you'll notice that the so-called environmentalists never oppose immigration. So how sincere can they be? Their main goal in life is to re-name lands that are already protected from development. In truth, farmers, ranchers and Ducks Unlimited have done far more for the environment than all the "environmentalists" and the EPA put together.
