Far from it. I'm a libertarian and an environmentalist. Pollution is harming other people just as clearly and directly as assault, rape or murder and so regulations against that harm still fit naturally and comfortably within even fairly extreme or hardline libertarian frameworks. A law that says "You can't spray mace in someone's face" and a law that says "You can't spray <whatever other harmful chemical> in <the air that will eventually hit people's faces>" are ideologically the same. Perhaps you meant it's a fascist, statist or autocratic dream? The people with power (economic, political, social) get to benefit while the people without power get harmed.
