Reasons for Becoming Vegetarian People choose to become vegetarians for different reasons. Some people follow a vegetarian diet because they believe killing animals is wrong. They see it as the ethical choice. Others choose vegetarianism for health reasons, as it can help them stay slim and lower their risk of various diseases. Recently, more people are switching to a vegetarian diet to protect the environment. Researchers from the Union of Concerned Scientists in the U.S. released a report on how consumer behavior impacts the environment. Their study showed that eating meat is one of the main ways humans harm the environment, second only to using motor vehicles. But how can changing our diets make a difference? We can compare the resources needed to produce meat and crops. For example, nearly 20,000 liters of water are needed to produce one kilogram of beef, but only 150 liters of water are needed to produce one kilogram of wheat. Similarly, one hectare (or 10,000 square meters) of farmland used for raising livestock produces about 227 kilograms of beef. The same amount of farmland can produce 13,600 kilograms of carrots, 18,000 kilograms of potatoes, or 22,700 kilograms of tomatoes. It’s clear that producing crops instead of meat makes more efficient use of land and water. Raising livestock also contributes to global warming. Animals like cows, pigs, and sheep release methane, a greenhouse gas that causes global warming, when they pass gas. One cow can produce about 500 liters of methane each day. A 2006 report by the Food and Agriculture Organization (FAO) says that livestock farming accounts for 37 percent of all methane production. Methane may have a more damaging effect on the atmosphere than carbon dioxide. There is growing support for vegetarianism. For example, schools across England and the U.S. hold "Meat Free Mondays" to show students how easy it is to eat less meat. Some people take it further and embrace a vegan diet, which excludes all animal products like cheese, eggs, and milk. However, some nutritionists believe that a vegan diet may lack essential vitamins and minerals. Question 34: Which of the following could be the best title for the passage? A.
