　　Pollution is the price we pay for an overpopulated, over industrialized(工业化的)planet．When you come to think about it, there are only four ways you can deal with rubbish：dump it(倾倒), burn it, turn it into something you can use again, try to produce less of it．We keep trying all four methods, but the rubbish we produce worldwide can cover us．

　　Rubbish, however, is only part of the problem of polluting our planet．People need to produce cheap food, this makes a different kind of pollution．Industrialized farming methods(方法)produce cheap meat products：beef, pork and chicken．The use of pesticides(杀虫剂)and fertilizers(化肥)produces cheap grain(谷物)and vegetables．The price we pay for cheap food may be already too high：Mad(疯的)Cow Disease(BSE)in cattle, salmonella(沙门氏菌)in chicken and eggs, and wisteria(利斯特杆菌)in milk products．And if you think you'll not eat meat and become a vegetarian(素食者), you have to choose the very the very expensive vegetables, but when you think you're eating fresh salads and vegetables, or just having an innocent(纯净的)glass of water, you are having the pesticides every time, in fact．
