Vegans don’t care WHAT you eat.
Vegans care WHO you eat.
Eat Like You Care: An Examination of the Morality of Eating Animals by Gary Francione and Anna Charlton puts the issue of eating animals squarely on the table. How can we justify the fact that we kill many billions of land animals and fish every year for food? However “humanely” we treat and kill these animals, the amount of animal suffering we cause is staggering. Yet no one maintains that animal foods are necessary for optimal health. Indeed, mounting empirical evidence points to animal foods being detrimental for human health. But however you evaluate that evidence, there can be no serious doubt that we can have excellent health with a vegan diet.
