I'm not sure what you mean by "without humans, we would have a lot more cows". Why do you think so?

We would have a lot more of all animals, fish, birds, etc without humans. That is without question.
I know exactly how co2 works. It's naturally produced and naturally cycled by plants, water, and dirt. Just like upper air above the oil/coal burning centers don't have higher co2 than the air over the ocean. co2 is not why LA is warmer.
It's going to get 15-20 degrees warmer, even if humans never produced a particle extra of co2.
