摘要
Yet for all that promise，biotech is fa r from being the whole answel.In developing countries，lost crops are not only one cause of hunger.Poverty plays the largest role.Today more than 1 billion people around the globe live on less than 1 dollar a day.Making genetically modified c rops available will not reduce hunger if fa rmers cannot afford to g row them or if the local population cannot afford to buy the foods those farmers produce. Nor can biotech overcome the challenge of distributing foods in developing countries.Taken as a whole，the world produces enough foods to feed eVeryone but much of it is simply in the wrong place.Especially in countries with undeveloped transpo rt infrastructu res，geography restricts food availability as d ramatically as genetics promises to improve it. Biotech has its own“distribution”problems.Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops.Thei r products are often too costly for poor fa rmers in the developing world，and many of those products won't even reach the regions where they are most needed.Biotech fi rms have a strong financial incentive to target rich ma rkets fi rst in order to help them rapidly recoup the high costs of product development.But some of these companies are responding to needs of poor countries.A London-based company，for example，has announced that it will share with developing countries the technology needed to produce vitamin-en riched “golden rice”. More and more biotech research is being carried out in developing countries. But to inc rease the impact of genetic research on the food p roduction of those countries，there is a need for better collaboration between gove rnment agencies-both local and in developed countries-and private biotech fi rms. ……
