Lisa Simpson is well known as an environmentalist in the television series, The Simpsons. This image of Lisa is from season seven, "Lisa the Vegetarian". You can see that Lisa is about to cut her food, Lamb chops, then visualizes a baby Lamb. Lisa is now knowledgeable of an animals' life. Lisa becomes a vegetarian due to a love of animals and a want to save them, not to hurt and consume them. This is one of the main reasons why vegetarians become vegetarians. We don't like the fact that an animal was murdered just for our satisfaction when we can eat substitutes such as tofu. Meat is not a key source of protein, we can get it anywhere else. The way I see it is, I don’t go home to eat my cat so why would I go somewhere else and eat someone’s farm animal?
