Antinaturalism...

Antinaturalism is a movement started in France that denies Nature any "sacred" status that must be preserved for its own sake. They believe that animals (epecially humans) have a right to live oppression-free and that it is OK for humans to ignore so-called Natural Law, especially in terms of eliminating predator/prey imbalances. To this end they encourage veganism in humans and, quite shockingly, in predator species as well. I'm not sure if you can train a carnivore to eat veggies, or if they're physically capable of making such a switch. I wouldn't want to be the first to offer an arugula salad to a hungry jaguar.
