Well wtf did you expect? Meat costs a ******** of energy, water and other resources to produce. Wich is why it's so annoying vegetarianism is always getting bashed by ignorant fools, just because a part of the vegetarians can't stfu about it.
There is also the whole thing about certain species of animals that we eat could not live on their own anymore because of how they've been bred over time, so if we stop raising them for food, they would in all likelihood die out.
want an animal off the endangered list, find a way to make them a profitable food source, sept **** like whales, I do not see a future whale farm
