A vegetarian is a person who does not eat meat. One major reason to do is is to reduce the amount of land use for cattle production. Another reason is to reduce the suffering of animals.
Some part time vegetarians have greatly cut back their meat consumption, and often use organically raised meats only.
Some vegetarians sometimes do not use animal products such as leather, fur, wool, or glutens.
