Animals would over run us or go extinct!
Both of these are lies.
The only way we have billions of land animals in the world is because people are breeding them - see animal are bred for a purpose.
If we stop jerking off the males and stop impregnating the females, there will fewer animals.
Over run is such a dramatic myth. What are the confined chickens in corrugated sheds going to form an army and take farmers hostage, like a Chicken Run film? Or are all the cows going to start driving cars and running people over? Come on. As I said before, if we take humans arms out of the cow's vaginas, they will stop breeding so much.
The extinction excuse ignores reality. The animals people mostly eat are genetic hybrids, like a Frankenstein version of their original descendants. More information here - https://www.businessinsider.com/what-farm-animals-looked-like-before-breeding-2016-2?r=US&IR=T
