While eco-freaks can be nuts, the notion that we can spew as many toxins into the air and water as we want, and believe that Mother Nature will protect us, is equally nuts.
Who is there, in reality, who ascribes to that notion? You may be falling into the leftist trap that any deviation from their preferred policies of tofu, wind and solar is evil.
Those who knowingly "spew toxins" are simply the amoral, who just don't care, 'cause they'll be dead anyway when it comes back to bite us.
