@ Cofy...at first I was going to argue your statement, but you know? You're right. A lot of those statements were supported by scientific facts. Still are in most cases. The problem was there wasn't a complete picture of the problems. Not enough study to formulate a proper conclusion. Just one side was researched and pushed to the extreme.
I see this same failed agenda today pushing global climate change caused by man-made CO2 emissions. See, I don't deny climate change. What I deny is the influence man has on it.
