Rational view of genetically modified crops
Recently, a series of news about genetically modified crops has aroused widespread concern in the society. From the U.S. farmland, the "unapproved" planting of genetically modified wheat to the Chinese Ministry of Agriculture approved the import of genetically modified soybeans. The promotion of genetically modified crops has become a hot topic for discussion. However, regardless of opposition or support, discussions and decision-making on genetically modified crops should be conducted with a rational and cautious attitude.
To treat GM crops, we must first take a rational attitude. Although the questioning and opposition to the crops such as genetically modified corn, soybeans, and cotton are currently on the global scale, in fact, as an important means of increasing agricultural production in the world, “transgenicization†has become the general trend of agricultural development in the world. Even the European Union, which previously strongly opposed GM crops, has already approved the planting of many GM crops. In addition, studies by authoritative agencies have also revealed that no genetically modified foods from genetically modified crops have been found to be harmful to human life.
The data released by the Food and Agriculture Organization of the United Nations in 2011 showed that 82% of cotton and 75% of soybeans in the world market have been genetically modified. The World Health Organization released a report in 2005 that GM crops traded on the international market have undergone rigorous examination, and no examples of human health hazards have been found in a large number of practices. Moreover, because of their high resistance to insect pests and high yields, transgenic crops also provide people with benefits such as increased yields and income, conservation of cultivated land, and protection of the environment. Completely negating GM crops is clearly untenable.
But at the same time, it should not be overlooked that GM crops are after all products of mankind's use of science and technology to transform nature. Although its negative impact on human health and natural environment has not yet been confirmed, it does not mean that these potential effects will not become a reality in the future. From this perspective, policy-making departments should be cautious when promoting GM crops, and they must take careful measures to prevent irreversible serious impacts in the future.
On this issue, some developed countries can learn from it. For example, according to the US legislation, each GM food is subject to review by at least three departments before being marketed. The Ministry of Agriculture is responsible for the management of GM crop development and field trials. The EPA is responsible for assessing the environmental impact of genetically modified plants. The FDA is responsible for genetically modified foods. And feed safety assessment. The listing of genetically modified foods must comply with traditional food hygiene standards. It takes several years for any kind of genetically modified food to be marketed, and it costs 10 million to 15 million US dollars to collect the data needed to complete the approval.
It should be noted that the promotion of genetically modified crops has always been accompanied by controversies, but it is also these controversies that have provided a steady stream of momentum to strengthen research on the safety of genetically modified crops and improve related regulatory mechanisms. The GM crops are not perfect, and human beings should not treat and treat them with scientific attitudes because they are not allowed to use food.
