Organic food: Why?
1. Europe is now the biggest market for organic food in the world, expanding by 25 percent a year over the past 10 years. So what is the attraction of organic food for some people? The really important thing is that organic sounds more "natural". Eating organic is a way of defining oneself as natural, good, caring, different from the junk-food-eating masses.
2. Unlike conventional farming, the organic approach means farming with natural, rather than man-made, fertilisers and pesticides. Techniques such as crop rotation(轮种)improve soil quality and help organic farmers compensate for the absence of man-made chemicals. As a method of food production, organic is, however, inefficient in its use of labour and land; there are severe limits to how much food can be produced. Also, the environmental benefits of not using artificial fertilisers are tiny compared with the amount of carbon dioxide emitted(排放)by transporting food.
3. Organic farming is often claimed to be safer than conventional farming. Yet studies into organic farming worldwide continue to reject this claim. An extensive review by the UK Food Standards Agency found that there was no statistically significant difference between organic and conventional crops. Even where results indicated there was evidence of a difference, the reviewers found no sign that these differences would have any noticeable effect on health.
4. The simplistic claim that organic food is more nutritious than conventional food was always likely to be misleading. Food is a natural product, and the health value of different foods will vary for a number of reasons, including freshness, the way the food is cooked, the typie of soil it is grown in, the amount of sunlight and rain crops have received, and so on. Likewise, the flavour of a carrot has less to do with whether it was fertilised with manure(粪便)or something out of a plastic sack than with the variety of carrot and how long ago it was dug up.
5. The notion that organic food is safer than "normal" food is also contradicted by the fact that many of our most common food are full of natural toxins(毒素). As one research expert says:"People think that the more natural something is, the better it is for them. That is simply not the case. In fact, it is the opposite that is true: the closer a plant is to its natural state, the more likely it is that will poison you. Naturally, many plants do not want to be eaten, so we have spent 10, 000 years developing agriculture and breeding out harmful traits from crops. "
