The CO2 and methane is produced by the animals.

" So if they can't even get studies that agree on which is a better method of getting weight off, how can they say their universal diet is healthy for everyone?" - what a ridiculous red herring. You have just said that if the science of diets is not perfect, then no-one can know the basics of climate science. Nice try, but no-one's buying that.

You keep on claiming things, without evidence, about how vegetables are grown in a much worse way than animals are fed. But animals are fed on mass-produced plants too. They get fed antibiotics too. They get hormones injected into them in some countries. And non of that is relevant to the basic point, which is about greenhouse gases.

"CO2 emitting produced chemicals" - WTF? You're just throwing words at the screen, in the hope some of them will make sense when seen together. You are making stuff up, without any reason or backing, in the hope of projecting the basic problem with meat - the greenhouse gases - onto anything you see as "the enemy" - "pampered easily damaged plants". Jesus, you're even anthropomorphizing plants is the desperate hope that makes them look bad.

No, the studies do look at the greenhouse gases involved in plant production; it's just that they're far smaller than for meat.

I assume from this you are a livestock farmer, and you can't bear the thought that you're involved in a significant climate-altering industry, so you're in denial.
