As ridiculous as I thought a lot of environmental regualtion in my younger years, I have come to appreciate breathable air (and from Deleware to NJ to somewhere west of Gary IN the air was not breathable) and clean water for recreation (the Charles River in Boston, the Potomac in DC, SF Bay, Cheasapeake Bay) and fishing. I would argue that there is nothing conservative in a free market in poisoning ourselves.
I would also agree that USG should divest itself of a lot of BLM land. I would draw the line firmly at National Parks, however. Conservatism will fail if conservatives propose to divest its national parks. Only a few of the hillucinatory branch of libertarians would be willing to die on that battlefield.
I agree with you. I remember how bad the industrial part of town used to be in my youth (driving by some plants you'd almost vomit) and the fish caught in some bays were not edible.
I am worried, though, about the way EPA has become a power in its own right, beyond the reach of legislators. You've noticed how they are being used to implement rules that Obama knows he can't get through congress.
So there has to be a way of pushing back.
