Goes into cow, comes out as methane. cow dies/meat --> co2. All the fossil fuel transportation for alfalfa to cow to brisket --> co2. Lot more co2 generated than absorbed.

But burning fossil fuels makes water, and also CO2 for the plants. The white, visible part of what you see coming out of a tail pipe is water vapor.

The main thing is, we are not making any new carbon that was not already here billions of years ago.
