One reason why it's easier to sell global warming to children

...they can't remember the 1970s.

Excerpt from this post:

On occasion I have the painful opportunity to talk to individuals about “Global Warming”. Those that are zealous believers, in my experience, tend to be young and liberal. The reason age is important is that I remember my teachers telling me as a child that we were destroying the planet because of pollution. Problem is that back in the 70’s we were being told that it was a coming Ice Age that would overtake the planet.
