Wow! Have you seen the award winning independent documentary "Cowspiricy"?
This documentary is at least as powerful as "an Inconvienient Truth".
It describes the enormous waste of resources and environmental damage caused by animal husbandry and deals not only with the unwillingness of governments to deal with this problem, but also with the unwillingness of large environmental organizations to deal with it as an issue, for fear of losing popularity and thus funding!
The perspective is that of one environmentalists personal journey as he tries to get to the bottom of the subject and the mysterious silence from all sides.
The Statistics given in terms of greenhouse gas emissions and water emissions are as mind blowing as the massive direct environmental impact (rainforest destruction, species destruction, poisoning the oceans, etc.)
The style is not at all "preachy" and remarkably even handed, all in all very watchable, even for the most red toothed carnivore amongst you
