What is the difference between animal rights and animal welfare?

"Animal welfare" is about general health conditions based upon experience and expectations. "Animal rights" is a politically energized concept based upon an aggenda for acquiring power. Please see discussion area Most animal welfarists argue that the animal rights view goes too far, and do not advocate the elimination of all animal use or companionship. They may believe that humans have a moral responsibility not to cause cruelty (unnecessary suffering) to animals. Animal rights advocates, such as Gary L. Francione and Tom Regan, argue that the animal welfare position (advocating for the betterment of the condition of animals, but without abolishing animal use: see veganism) is logically inconsistent and ethically unacceptable. However, there are some animal rights groups, such as PETA, which support animal welfare measures in the short term to alleviate animal suffering until all animal use is ended
