By that same logic, fossil fuels are carbon neutral because they come from living things.

The problem is we have too much carbon dioxide in the atmosphere, not too much of various assorted carbon-based compounds on the planet.

But the supply of herd animals is essentially fixed. There isn’t infinite growth. Eating meat therefore does not increase the amount of CO2 in the atmosphere, no matter what vegans who want to ban meat for personal moral reasons assert.

If humans stopped eating meat, the only way to reduce the amount of carbon that animals “emit” would be to kill all of them and bury their carcasses underground where they can’t decompose (as that would turn them into CO2).

Burning oil introduces new carbon into the cycle, animals existing does not.
