If this were not the case and the numbers were natural, the planet would be consumed by cows in a short number of years.
The reason there are so many cows is because people are breeding them into existence. There are far more cows now than there would be if people were not eating them. I’d rather be extinct than be sexually abused by humans, have my children killed at a fraction of their lifespan, and live in filth like most cows do.
Instead of breeding more animals, we should let the ones alive now live out their natural lifespans and stop breeding them. But as long as people keep buying animal products, breeders will keep breeding the animals.
