题目

However,like any new product entering the food chain,GM foods must be subjected to careful testing．In wealthy countries,the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from,and a supply that goes beyond the needs．In developing countries desperate to feed fast-growing and underfed populations,the matter is simpler and much more urgent:do the benefits of biotech outweigh the risks?
