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 animals are bred for a purpose.
If we stop jerking off the males and stop impregnating the females, there will be 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 human's 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
So the original animals will still exist. And the animals that live in sanctuaries will live. Overall eating animals causes pain and suffering to others, so we should stop using these baseless excuses to justify our selfish taste pleasures.
