No, because they're idiots that don't understand basic biology. They're not pro-animal, they're anti-human (which is ironic, since we're animals, too).
Not yet. You have to understand that they ar working this whole thing in stages. First, they get everybody to eat greens and bushes. Not any large ones of course because they have a deal with the Sierra Club. Then they are going to guilt us on killing insects and spiders. A bit of a tougher sell when it comes to roaches, but they feel they are up to the task.
So, the plan is that when we are all on our knees eating grass, covered with ants and lice, they will attempt to re-train the carnivorous animals to respect all living things.
It may take time. However their plan, as I understand it, is to stone to death any animal that even thinks about eating another. Tough love, to be sure, but necessary for the end results.
