Yuan Longping talks about genetically modified foods
Yuan Longping said that genetically modified foods cannot be generalized
The promotion of pest-resistant transgenic varieties should be prudent
In response to various questions raised by the community on genetically modified foods, on March 3rd, Yuan Longping, member of the National Committee of the Chinese People's Political Consultative Conference and “father of hybrid riceâ€, said in an interview that genetically modified foods cannot be generalized, and genetically modified pests should be promoted when they are promoted. Be cautious.
"The genetically modified foods cannot be completely or completely unacceptable. Some of them have no safety problems, but some still require further in-depth research on their safety." Yuan Longping said that through genetic modification technology, humans can be more in tune with themselves. The required good quality, high yield, nutritious and resistant to pests and fine varieties, but may also cause biological genetic contamination.
"For example, the poison protein gene is very good for pest control, but people are worried that it may have an adverse impact on human health." Yuan Longping said that this makes sense, and the state is very cautious about this problem. It is now resistant to pests. The GM varieties did not release the production market and are still in the experimental stage.
"But we can't kill GM foods and think GM foods are bad. Some GM foods are not toxic and can't be considered to be problematic," Yuan Longping said. Rice and wheat belong to carbon 3 plants. Sugarcane is a carbon 4 plant, and its photosynthetic efficiency is 30%-50% higher than that of the former. Now they have transferred the carbon 4 gene of maize to rice to increase their photosynthetic efficiency. "I don't think there is any food safety issue for such GM varieties."
Yuan Longping said that the use of biotechnology to develop crop breeding is the future direction of development and an inevitable trend. Transgenic technology is a class of molecular technologies. Therefore, it is necessary to strengthen the research and application of transgenic technology. Treating genetically modified foods, especially genetically modified varieties that can be consumed directly, should take a scientific and prudent approach, but it cannot be simply rejected.
He said that due to the potential risks of genetically modified foods and factors such as genetic pollution, proliferation, proliferation and indeterminate removal routes, once genetically modified organisms have problems, they cannot be controlled at all, and no one can take responsibility. "It's a very long time for GM foods to hurt the human body. It takes at least two generations to come to a conclusion."
Yuan Long flatly stated that public concern about the safety of genetically modified crops is mainly due to the fact that some genetically modified crops, especially those resistant to pests and diseases, are genetically derived from a bacterial protein. Since insects eat toxic proteins and can be poisoned, it is difficult to say whether long-term intake of the substance is harmful to humans. “The experiment can't be done by people. It's all through mice. But humans are humans. White rats are white rats. They don’t harm the white rats, but they’re not necessarily harmless to people. People and their bodies are different. Therefore, it is necessary to be cautious and cautious about some disease-resistant and insect-resistant genetically modified foods, and to make a systematic safety assessment.
"If the genetically modified pest-resistant rice is to be tested by the human body, I will be the first to apply." Yuan Longping said that as long as two generations do not have problems, it shows that this genetically modified food is safe.
