Comic Book calibre conflict

PETA teams up with Glen Beck to chastise Al Gore?

First of all, until PETA can explain how an animal that spent a million (give or take) years evolving around a diet of hunted animals and foraged fruit can achieve a sustainable diet without the meat , scientifically, they should just stick to protecting animals that don't exist purely by virture of domestication.

Second, Beck is the kiss of death for any reasonable argument, and redundant for unreasonable ones. I saw this bit, and he hardly was arguing for PETA's cause. In fact, its really hard to get any points out of it. It would be funny if it was not so sad.

Third, if we solved our ecological issues in a way that allowed for sustainable meat food industry , would environmentalists no longer get support from PETA?

Strange priorities...
