I think paleo-tainment TV shows are great. Not everyone is going to join the Society for Primitive Technology, become a hunter, or even a Boy Scout/Explorer. Any attempt to walk down a simpler path, even after being inspired by a TV show is a good thing in my book. Haters can eat beetle larva, so HA ;-P
What's interesting is that this tradition is a continuation, not a novelty. In the first, "Oh, no, a Democrat! The end is near" administration of Jimmy Carter, we had the Survivalist craze (Donald Petri's prescient film "The Survivors" is still worth a viewing). That craze turned into the militria movement during the years in between, but there has always been a segment that thought that getting manly and eating bugs was an American virtue for the virtuous.
As sad as it is these men making these reproductive rights decisions don't really care about the moral aspect of the argument. It's really all about control. If they really cared about this issue they would be teaching our children sex education, and providing affordable contraceptives in the school system.
That video was like nothing I've heard before. As for climate change, it's here now and we as a society can work towards mitigating the effects through conscious choices and actions if we are aware.
