The role of religious beliefs on the question of meat eating can take people in different directions. As far as I know, Hinduism is the only major religion that unequivocally advocates vegetarianism. Surely it is no coincidence that the tastiest vegetarian meals can be obtained in the homes or restaurants of Hindus. Hindus really know vegetables.
Buddhism seems a little more equivocal because there are many variations of that religion. While it says that individuals should not kill anything, even insects and pests, some Buddhist philosophers assert that it is acceptable to eat meat from animals that were not specifically killed for you for that purpose (Writings on an Ethical Life, Peter Singer (2000), p. 68). In other words, buying and eating a hamburger from a store is acceptable because that animal was not killed specifically to meet your needs, is now dead anyway, and your not eating the hamburger is not going to bring it back to life.
