问答题 "You don't have to wait for government to move … the really fantastic thing about Fairtrade is that you can go shopping!" So said a representative of the Fairtrade movement in a British newspaper this year. Similarly Marion Nestle, a nutritionist at New York University, argues that "when you choose organics, you are voting for a planet with fewer pesticides, richer soil and cleaner water supplies."
The idea that shopping is the new politics is certainly seductive. Never mind the ballot box. vote with your supermarket trolley instead. Elections occur relatively rarely, but you probably go shopping several times a month, providing yourself with lots of opportunities to express your opinions. If you are worried about the environment, you might buy organic food; if you want to help poor farmers, you can do your bit by buying Fairtrade products; or you can express a dislike of evil multinational companies and rampant globalization by buying only local produce. And the best bit is that shopping, unlike voting, is fun; so you can do good and enjoy yourself at the same time.
Sadly, it's not that easy. There are good reasons to doubt the claims made about three of the most popular varieties of "ethical" food: organic food, Fairtrade food and local food. People who want to make the world a better place cannot do so by shifting their shopping habits: transforming the planet requires duller disciplines, like politics.
Organic food, which is grown without man-made pesticides and fertilizers, is generally assumed to be more environmentally friendly than conventional intensive farming, which is heavily reliant on chemical inputs. But it all depends what you mean by "environmentally friendly". Farming is inherently bad for the environment: since humans took it up around 11,000 years ago, the result has been deforestation on a massive scale. But following the "green revolution" of the 1960s greater use of chemical fertilizer has tripled grain yields with very little increase in the area of land under cultivation. Organic methods, which rely on crop rotation, manure and compost in place of fertilizer, are far less intensive. So producing the world's current agricultural output organically would require several times as much land as is currently cultivated. There wouldn't be much room left for the rainforest.
Fairtrade food is designed to raise poor farmers' incomes. It is sold at a higher price than ordinary food, with a subsidy passed back to the farmer. But prices of agricultural commodities are low because of overproduction. By propping up the price, the Fairtrade system encourages farmers to produce more of these commodities rather than diversifying into other crops and so depresses prices—thus achieving, for most farmers, exactly the opposite of what the initiative is intended to do. And since only a small fraction of the mark-up on Fairtrade foods actually goes to the farmer—most goes to the retailer—the system gives rich consumers an inflated impression of their largesse and makes alleviating poverty seem too easy.
Surely the case for local food, produced as close as possible to the consumer in order to minimize "food miles" and, by extension, carbon emissions, is clear? Surprisingly, it is not. A study of Britain's food system found that nearly half of food-vehicle miles (i.e., miles traveled by vehicles carrying food) were driven by cars going to and from the shops. Most people live closer to a supermarket than a farmer's market, so more local food could mean more food-vehicle miles. Moving food around in big, carefully packed lorries, as supermarkets do, may in fact be the most efficient way to transport the stuff.
What's more, once the energy used in production as well as transport is taken into account, local food may turn out to be even less green. Producing lamb in New Zealand and shipping it to Britain uses less energy than producing British lamb, because farming in New Zealand is less energy-intensive. And the local-food movement~ s aims, of course, contradict those of the Fairtrade movement, by discouraging rich country consumers from buying poor-country produce. But since the local-food movement looks suspiciously like old-fashioned protectionism masquerading as concern for the environment, helping poor countries is presumably not the point.
The best thing about the spread of the ethical-food movement is that it offers grounds for hope. It sends a signal that there is an enormous appetite for change and widespread frustration that governments are not doing enough to preserve the environment, reform world trade or encourage development. Which suggests that, if politicians put these options on the political menu, people might support them. The idea of changing the world by voting with your trolley may be beguiling. But if consumers really want to make a difference, it is at the ballot box that they need to vote.
问答题 Paraphrase the sentence "Never mind the ballot box. vote with your supermarket trolley instead". (para. 2)
【正确答案】Elections occur relatively rarely. But lots of people believe that when people do shopping, it is also a good opportunity to express their political views. People who are concerned about environmental protection might buy organic food; People who want to help poor farmers can buy Fairtrade products. People who dislike the evil multinational companies and rampant globalization can buy only local produce.

问答题 What is "organic food"? Why does the author believe that it may lead to the problem that "there wouldn't be much room left for the rainforest"?
【正确答案】Organic food is the food grown without man-made pesticides and fertilizers. Organic agricultural methods rely on crop rotation, manure and compost in place of fertilizer. The "green revolution" of the 1960s initiated greater use of chemical fertilizer, and tripled grain yields with very little increase in the area of land under cultivation. But now, the organic agricultural methods are far less intensive. If we produce the world's current agricultural output organically, we would require several times as much land as is currently cultivated. That's why the author believe "there wouldn't be much room left for the rainforest".

问答题 How is "Fairtrade food" designed to help poor farmers? According to the author, can this goal be achieved?
【正确答案】Fairtrade food is designed to raise poor farmers' incomes. It is sold at a higher price than ordinary food, with a subsidy passed back to the farmer. Prices of agricultural products are low because of overproduction. But since the prices are raised, farmers would be reluctant to diversify into other crops, they would continue to produce more of the over-produced products. And in fact, only a small fraction of the subsidy on Fairtrade foods actually goes to the farmer—most goes to the retailer. The system gives rich consumers an illusion of their generosity and makes alleviating poverty seem too easy.

问答题 How is the "local food" generally believed to help protect the environment? Why does the author say that "local food may turn out to be even less green"? (para. 7)
【正确答案】Local food is produced as close as possible to the consumer, so that the "food miles" would be minimized, and thus, by extension, carbon emissions were also minimized. But a study found that nearly half of food vehicle miles were driven by cars going to and from the shops. Since most people live closer to a supermarket than a farmer's market, more local food could mean more food-vehicle miles. What's more, once the energy used in production as well as transportation is taken into account, local food's impact on environmental protection should be further questioned.
