However, A lot of animals are only bred for the pure reason of creating produce to sell and to be eaten, it gives money to farmers, and also if everyone stopped eating the meat then they may stop selling the meat and breeding the animals. In other words they could become extinct. Don't get me wrong I have absolutely nothing against vegetarians and vegans (my boyfriend is even vegetarian) and i know a lot of the animals are treated horribly, and I understand that.
Extinction is an ecological problem, while most farm animals do not exist inside of a natural ecology. If all the cows went extinct, that would be ecological fine (actually, beneficial) because they are not natural animals, they were created by human breeding. There has never been a wild cow in the history of ever….though cow ancestors (like bison) are still around, the direct natural ancestor of the cow, the Auroch, is already extinct.
Pigs would not go extinct…they live in the wild in lots of places. Chickens probably would…though their wild counterparts are also doing fine.
The question of “what would happen if all people stopped eating meat” is a very interesting one. I would like to answer that question…possibly a very good video idea…
But I can’t really imagine that people will stop eating meat unless meat becomes completely unavailable.
