It was the hemp argument that led me to discarding Al Gore's argument many years ago, back when I believed everything I was programmed to believe. The fact that he discarded hemp as a serious solution to the problem he was presenting proved was a red flag on BS. If man made global warming was really a threat to humanity, they would have incorporated it into the solution a long time ago. But it isn't, and they didn't, because their real motives are something altogether different.
