What is Right and Wrong?

I believe that many people do not understand the real difference between Animal Rights and Animal Welfare. Animal Rights include the belief that animals should never, under any circimstances what so ever, be exploited. This means they should not be used for food, research, or even as pets. Animal Welfare involves the humane and proper treatment of animals. This includes being fed and water properly, and being provided with the proper healthcare and protection. Animals are also not to be abused. So Which is better? Is Animal Rights over the top? Does Animal Welfare not protect animals enough? I am borderline on both. I do not believe animals should be used for research, however without the use of animals for research, there would be far less medications. Also I do believe in eatting meat, and animal by-products. As far as Animal Welfare, I believe in it 100%, however, I believe some requirements should be strictor in how animals legally must be treated. Just because a dog has food, water, and shelter, should not mean that they can be left outside tied to a tree all day. Let me hear what you all think of this controversial topic.
