Yes, nature designed it that way, and it is kind of like reproduction, I know what you mean, but not to this extent. Almost every wild animal is endangered, we are destroying the o-zone and filling the earth with crap. Humans and animals were all designs to have equal rights, but people seemed to have changed that. Animals do feel, and if you look the picutes of monkeys on that site you will see they are not very diffrent peeople, beeting a monkey to death in my opinion is just as bad as beeting a person to death. I'm sure you'll all hate me for saying that but I know Push can back me up on that.
