Ethical treatment of the animals.
Anyone who truly cares about animal rights should be able to call themselves vegan. I suppose the general term is an animal rights activist.
Hunger
The one eating is called consumer. The organism killing and eating another is called a predator. The other animal is prey.
A beasty is another term for a beastie, a slang term for a beast or animal.
Same right
parasitic hurts the animal the term is mutual
A zoolith is another term for a zoolite, a fossilized animal.
Parthenogenesis
Rights.....i.e. Mineral Rights, Lumber Rights
Yes, they mean the same thing. Animal rights is the ideology behind the animal liberation movement. Animal liberation is the ultimate goal of the movement, and the latter term is used more often because I think animal liberation sounds more radical and unsettling.
Smart, intelligent, brainy, cool -- there's lots of words! :)I'd say the person is a moderate (if he or she has mixed feelings) or that he or she is a critic of the animal rights movement.
None. "Factory farm" is just a term coined by animal rights activists.
