More action without knowing the actual cause. Little real study is going on. Its all politics and suppression of those who want real facts. I have been around long enough to know that our air is cleaner than 50 or even a 100 years ago. We have been working on reducing real pollution while others are trying to ban mankind and all modern technology. We should not bankrupt ourselves while China, India, Pakistan and others are increasingly creating far more pollution every day. So called science has had these religious like movements from time immortal thereby oppressing real scientific research.
