tes a lot of that carbon dioxide. And much of meat’s contribution es from beef, which is responsible for releasing even more warming gases into the atmosphere. The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼氣 ) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed and shipped to a shop, which takes fuel. Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment. We can reduce the production of globalwarming gases by eating less beef. Other kinds of meat like pork and chicken do less harm to the environment 梐 t least in terms of the amount of greenhouse gases released.. All kinds of meat are harder on the pla than vegetables. To grow and eat a pound of potatoes, for example, sends less than onequarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good. 24. The questions asked in the first paragraph are used to _____.
