Eating Animals

This is a response from the article Eating Animals from the website www.bbc.co.uk/ethics/animals.  In the article, the main argument is raising and killing an animal for food  is morally wrong.  A question that arose while reading the article was if raising and killing an animal for food is wrong, then what about killing an animal that lives in it's natural environment, such as a deer, for food?  I agree with the fact of a dog or cat that is a pet having rights.  I however, disagree with the utilitarian's point of view on animal rights when it comes to cows, pigs, and chickens being used for food.  Animals have been used for food and human needs for as long as one can remember therefor I don't see what the problem is.  Sure if a dog or cat is being abused then action should be taken for stopping it but eating cows and pigs should be left up to the person who is eating them.  Animals are animals and humans have control over animals, so the fact that some people raise and kill them for food should be left alone and up to those people on how the animals are treated.
