"Animal rights movement refers to organized efforts opposing the use of animals for research, food, clothing, and human entertainment ... The animal rights movement developed out of the animal protection, or animal welfare, movement. These movements have slightly different opinions on how animals may be used. The animal protection movement tends to accept the need to raise animals for food and to use them in some research as long as they receive proper care and do not suffer. In contrast, the animal rights movement opposes any use of animals that causes suffering or death."
