NO CHANCE, The animals have done nothing to deserve extinction, IF and i emphasise that if, but if the masses all gave up meat and joined the cult of vegantard, then cows, pigs, sheep and chickens all become extinct because the farmers no longer have any incentive to keep the animals alive and breading. Sorry but i am the epitome of an omnivore, meat and 2 veg daily, and this will never change :)
