in order to feed all the animals that humans torture and slaughter every year (approximately 80 billion of them) you need to grow food. the amount of food needed every year is significantly larger than anything you would need on a vegan diet. meaning, if everyone switched to a vegan diet, humanity would be exploiting much smaller number of third world farmers and killing significantly smaller number of animals and insects. so if you care about third world farmers, small animals and insects you should go vegan.
