I would suggest you get a hold of Penn and Teller's B.S. show, from Showtime, that talks about the Endangered Species Act. I got it from Netflix and it was quite an eye opener. Consider the fact that it was passed by the Nixon administration and you will come to realize that it was a way for the government to control land without having to pay for it. We all know what a great conservationist Nixon was <sarcasm>. They showed a disabled lady in a wheel chair who was not allowed to build a home on land she owned because of a protected bird in the Jay family, even though no one had ever seen one on her land. A few hundred feet from her land, Wal-Mart was given permission to build one of their huge stores. Stories of how the ESA has helped the animals that were listed are dubious at best. The show will get your blood pressure to rise a good deal.
