Farm animals face torturous conditions and are slaughtered in increasing numbers because of increasing world demand for meat. Meat is largely expensive because allot of roaming land is needed to raise livestock, but stem cell meat promises to be cheaper and better and we can release livestock to the wild. Animals through out the world can be protected in large preserves, and predatory animals, fed stem cell meat, will lose their predatory instincts, and animals can be sterilized in increasing numbers to prevent over-population, with less hunting and predatory killings by other species.
