@surfnscientist The vegan folks are claiming eating animals that eat plants has a larger carbon footprint than just eating plants, but where does this alleged extra carbon come from? They are both made from atmospheric CO2 are they not?

Good question. I eat meat🤫which causes more warming than eating plants because e.g. methane absorbs more infrared energy than CO₂. Emitting 1 CH₄ molecule is equivalent to emitting 25×CO₂. It's CO₂eq that matters not just the number of C atoms emitted bbc.com/news/science-environ…

But if humans digest the plants instead of animals doesn't that just move the methane emission to a different emission source?

Ruminants are better at digesting plants than we are, we have to eat more plants to extract the same amount of energy and amino acids than if we let them do it for us. Also the fibre we can't digest is still broken down by bacteria inside or later outside the body, it's not free.
