"Village Idiot, the documentary thankfully backs up the statements with facts. Have a read:

Interesting, I'll need some time to trace the citations back to their primary sources.
One thing that struck me though, at the 1 minute mark on the first video on your link, Will Tuttle says that human beings and their animals presently make up 98% of the biomass. He doesn't make it clear that he's talking about animals only. When you include biomass you have to take plants and animals combined. The houses that we live in, mostly made from wood, have more biomass in them than we do.
I don't deny that water usage is exorbitant though. Especially in California where I live. 80% of all water consumed there is for agriculture with water intensive plants like alfalfa which is shipped to China for cattle feed.
Also, the first point titled "Animal agriculture is responsible for 18 percent of greenhouse gas emissions, more than the combined exhaust from all transportation." makes it clear that animal husbandry emits only one fifth of what everything else does.
What I advocate is an 80% reduction in fossil fuel usage of automobiles, electricity and other uses. Without reducing animal consumption at all that savings would account for 34.4+% of our current usage. Not as much as I'd like but it would be major progress.
I believe in permaculture (In the context of a different civilization replacing ours - a million ecovillages). As for meat, I would like to see the growing of laboratory meat in full scale production. That would take far less resources than what we're using now. We could have that within 20 years.
