Speciesism refers to the common assumption of the ultimate superiority of the human race. This belief involves a human assignment of different types of rights, values, and consideration to different species depending on their use and functions.
For example, most people see pets, farm animals, and wild animals as different categories of animals with different functions. For instance, some people eat rabbits and some people have pet rabbits. Speciesism is the belief that animal rights activists claim leads to the abuse and exploitation of animals.
