Discuss the implications of moral consideration on some of the following

practices involving nonhuman animals: meat-eating habits, pet ownership, the use of nonhuman animals in experimentations, and keeping animals in zoos.

-In what ways do the above actions represent incompatible, even contradictory, moral values? 
-Do humans have a moral obligation to modify our lifestyle in order to recognize the moral status of nonhuman others? 
-Do you believe any of the nonhuman animals mentioned above (pets, farmed animals, zoo animals, etc.) would qualify as moral subjects, and perhaps even moral agents? 
-Which ethical theory (utilitarian, social contract, Kantian, etc.) is most consistent with your outlook on animals?
