If God put animals on this earth for us to eat them, why would he give them a central nervous system that allows them to feel pain and suffering? As well, ask people if they believe that any benevolent good natured God would be acceptable of UNNECESSARY pain and suffering to innocent creatures. Animals being forcefully impregnated, having their children stolen, living in horrible conditions, being mutilated and slaughtered all for us is not something I believe God would encourage just so that we can have a bacon sandwich when we can get the nutrients from other sources. I am not religious, but I do believe "thou shalt not kill" is a commandment that applies to all living sentient beings.
