This video has nothing to do with cute, fuzzy animals... there are no sad cow eyes or images of brutalized chickens. The video also says nothing about diabetes, obesity or other human health implications of eating flesh. It's just about the ecological issues - just the fate of the planet if we continue our meat eating habits... that's all - "just" the planet.
And to avoid this peril, all we have to do is just go vegan. The solution is that simple.
