"Im gonna eat twice the animals YOU do", not ".. twice the animals I used to"

So, they'll prolly die of congestive heart failure 20 years earlier, meaning... 80 years of meat consumption minus 20 years of life = 120 years of lifetime consumption at a 2x meat consumption rate... If both you and they'd eaten an omnivore diet and lived to 80 that'd be 160 years of cumulative consumption so we're still ahead.

I hope their principals make up for their significantly reduced quality of life
