So, is it good to have a department (the EPA) to help clean up messes like this, and to rein in egregious industrial abuses? I would say, "Yes".
BUT (and you knew this 'but' was coming....), does the EPA need to regulate industry out of existence to preserve habitat for spotted owls, polar bears, assorted bugs+mollusks, and so forth? Nope. Frankenstein's monster is the classic metaphor.
So....Conservatives and other sensible people are forced to argue AGAINST creation and expansion of these agencies, just to rein in their terrific abuse. It's a lose-vicious circle, IMHO.
