Context: Based on the research, the number of animals slaughtered is 2000 animals per second. This is just for the animal's slaughter. Humans kill and torture animals for many other reasons. Some are for food, for scientific experiment. And some are just for seeking of excitement. If we add all those reasons together, the number of animals that be killed by humans will be astonished. This phoneneon also accelerates the increasing number of extinct animals which means we are affecting the whole eco-system. We, as humans, always kill and torture other animals as we want just because we are more powerful than those animals. Disruptions: Is it morally acceptable for a human to kill or torture any animals as we want? Some might say that Every being has the intrinsic value to survive, and we do have the right to control other’s life. Others might argue that the world itself is a hierarchy system; we as humans are at a higher level of the hierarchy system, so we have the right to control animals. Response: I think whether killing or torture animals is morally right or wrong should depend on the purpose of the action. If killing animals is the best or the only choice to achieve the purpose, then I think it is morally acceptable. If other options can achieve the same purpose in a better way, then killing and torture is not acceptable.
