10.Food production does great harm to our environment.There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants.Some procedures require the consumption of large amounts of fossil fuels,such as the transportation and storage of food products.Other factors that cause great damage to our environment include the overuse of fresh water.The production of beef is more damaging to the environment than that of any other food we consume,Raising large numbers of cattle requires the production of large amounts of food for the animals.It's estimated that producing one pound of beef requires seven pounds of feed.
Land use is also a problem.If the cattle are free-range cattle,large areas of land are required for them to live on.This has led to disastrous forest cutting and the loss of rare plants and animal species,particularly in tropical rain forests in Central and South America.
Another problem specific to beef production is methane emissions(甲烷排放).Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,making it a more dire problem.
Unfortunately,beef consumption is growing rapidly.This is the result of simple supply and demand factors.Specifically,there are two main causes of demand that are encouraging the production of more supply.First,the increase in the world population means there are more people to consume meat.The second factor is socioeconomic advancement.As citizens in developing nations become financially stable,they can afford to buy more meat.
Therefore,one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

分析 本文讲述了生产牛肉给环境带来的危害,希望可以使人们降低牛肉的消费.
解答 32.C.细节理解题.由第二段The production of beef is more damaging to the environment than that of any other food we consume可知,生产牛肉特别损害环境,故选C.
33.A.词义猜测题.由前一句Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,虽然很多人都知道二氧化碳的破坏性影响,但是他们没有意识到甲烷的全球变暖潜能是二氧化碳的25倍,这是一个更可怕的事情,故选A.
34.A.细节理解题.由倒数第二段the increase in the world population means there are more people to consume meat,可知人口的增长导致需要更多的牛肉,故选A.
35.D.主旨归纳题.由最后一段one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.可知作者希望可以使人们降低牛肉的消费来减少温室气体排放,故选D.
