Off course cows aren't the only source of meat, and of course methane can be used as energy instead of letting it go into the atmosphere. Also most ranchers want to reduce methane production, because it decreases digestion efficiency in animals.

Obviously one has the same transport costs for non-animal feed for humans, and since to get a decent amount of protein on a non-animal diet, one would have to eat soy products like tofu that are actually concentrated soy products, or a much larger amounts of beans, my guess is the transport and production costs end up very similar. Tofu production creates its own waste problems, most of which now goes to feed livestock. Soy and other bean crops need more land and water than many grains used for feed. The worlds rice paddies create more methane gas than all ruminants(like cows) combined.

The question also is, if humans eat an all vegetable diet will they produce more methane than if they eat a mixed diet?(most likely yes, especially if they eat high soy diets) what is the difference if any between the two, and how does it compare to pasture raised white tailed deer(produce much much less methane than cows per kg of meat, plus meat has higher protein density), whose waste is collected, and methane used for energy. Or chickens whose waste is collected and methane used for energy. Chickens are very efficient at converting grain to meat(2 to 1), use less water, and their methane production to the atmosphere would be somewhat easy to control.
