内容摘要
The U.N. estimates that nearly 800 million people around the world are undernourished. The effects are devastating. About 400 million women of childbearing age are iron deficient， which means their babies are exposed to various birth defects. As many as 100 million children suffer from vitamin A deficiency， a leading cause of blindness. Tens of millions of people suffer from other major ailments and nutritional deficiencies caused by lack of food.
How can biotech help? Biotechnologists have developed genetically modified rice that is fortified with beta-carotene which the body converts into vitamin A and additional iron， and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to pests， drought， poor soil and crop viruses， bacteria or fungi. Damage caused by pests is incredible. The European corn borer， for example， destroys 40 million tons of the worlds corn crop annually， about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa， yields have increased significantly. So far， fears that genetically modified， pest-resistant crops might kill good insects as well as bad appear unfounded. Viruses often cause massive failure in staple crops in developing countries. Two years ago， Africa lost more than half its cassava crop a key source of calories to the mosaic virus. Genetically modified， virus-resistant crops can reduce that damage， as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum， which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity in rice has been identified.
