The point is that it is much more land efficient for us to directly eat plants than to route the plants through animals first. Cattle use 99% of the calories we feed them for their own functioning. Only 1% actually make it into the meat that we eat.

I wasn't proposing any specific solution, just stating that eating animals does in fact contribute more CO2 than eating plants. And I have no problem with carbon taxes, in fact I'm in favor. A carbon tax could certainly cover this case if it taxes the CO2 that animals emit.
