Ever since they were first put on the market in the early 1990s, genetically modified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solution?
Despite what it promises,GM
technology actually has not increased the production potential of any corp. In fact
Studies show that the most
crown GM crop.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides(杀虫剂). On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The
promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition.
