Reply #9: I realize the ecological impact that there is right now...

but the question remains: What happens to all of the animals that are here now? Do we let them just run wild? Who is going to keep paying to feed animals that have no return value on their investment? Do you sterlize herds so they can't reproduce, then let them die out? We won't need them anymore, right? You can't kill them and eat them or make clothes with them, so what good are they? If not, you're not reducing their presence or the amount of harm that they cause. In fact, you'll be adding to the problem as the populations grow. More methane emissions, more water and land consumption, more land being used for feed crops to feed the booming herds.

What natural predators are going to keep the cows & hogs in check? What happens when natural predators get overpopulated? How many attacks on humans would it take before we needed "predator eradication" hunts?
