Are GM（转基因的) foods safe for people? Can they help solve the poverty problem? They have been the subjects of a hot debate.
This debate is related to increasing challenges from rising climatic change, population growth, urbanization（城镇化), and natural resource consumption. According to the Food and Agriculture Organization, food production needs to increase by 60 percent by 2050 in order to feed 9 billion people. Scientists and policymakers are searching for effective ways to gain nutritious food, for today and future. Unlike previous agricultural methods (such as the Green Revolution), GM crops are to fight food safety and poverty challenges.
The great expansion of GM crop varieties over the last two decades can be seen easily. The total area devoted to GM crops has increased 100 times from 1.7 million hectares in 1996 to 170 million hectares in 2012. Developing countries now grow more GM crops than developed countries (in terms of area), largely driven by Brazil’s rapid adoption of GM crops. China is home to about 4 percent of the total global area devoted to GM crops. Beans, corn, and cotton are main global GM crops, while China’s focus is on cotton, papaya, and poplar.
Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU, “the main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 research groups, is that biology methods, are not more risky than traditional planting technologies, for example.” Other international and national scientific bodies, such as the World Health Organization, have reached the same conclusion.
