Partially true and I know it but I don't give a F anymore now the world has a government that'll only speed up ecological demise. I feel veganism (or at least reducturianism) is a (albeit very small) chance to slow that down. Thanks for giving me the forum to spew my propaganda.

Partly true because you wrote the system is conserving resources where it really doesn't. Most of the energy is transformed into non-conserving but destructive forces: GHGs, manure run-off, pollution. A whole lot of energy is used to grow the miserable animal and only a fraction of it is coming out in form of quickly perishable food.

I addressed the 2/3 crop calorie argument already in my previous post. That's not what the original video was addressing. It was addressing the amount of crops (therefore land use, therefore number of rodents dying on harvest). Again your paper states we could ramp up the production of calories from plants just for humans and could feed some billion more people.
