I remember visiting LA in the late 80's and having my eyes water due to the pollution. I can't imagine what the 60's and 70's must have been like. Unfortunately it is only easy to be an environmentalist in this country only when lakes are burning and the air is so bad you choke on it. We should have national pollution park where companies are allowed to do whatever they want but it is also a national park that has guides to show how bad things are just so people can understand what life is like without environmental controls.
