According to Voices of China's “News Evening Peaks†at 17:43, a group of pictures has recently been circulated on the Internet. Some are watermelons with big eyes and six legs, and some are squirrel-tailed monsters. There are no such species in the world. The pictures synthesized by software are rendering the fear of transgenic technology.
Transgenic technology and traditional crossbreeding are essentially the same
In the supermarket, the most discounted edible oil is genetically modified soybean oil. There are many people who buy it, but few understand it. What is genetically modified soybean? At today's China Association of Science and Technology conference, Lin Min, director of the Institute of Biotechnology of the Chinese Academy of Agricultural Sciences, said that genetically-modified technology and traditional cross-breeding are essentially the same and have scientific theoretical basis.
Lin Min: Transgenic phenomena are common in the natural world. Working people have used this transgenic phenomenon to breed the animals at a very early time. The traditional hybridization technology is gene transfer. Then the transgenic technology may target a very clear target gene. Accurate transfer to the life of the recipient.
Last year, the total area of ​​global genetically modified crops was 134 million hectares. Three-quarters of the total soybean area, half of cotton, one-fourth of corn, and one-fifth of rape were genetically modified. Hundreds of millions of people eat genetically modified food each year. Among them, 70% of the food in the U.S. market contains genetically modified components, and most of the soybean oil consumed in China is also a genetically modified product.
The difference between transgenic and non-transgenic is very small
Followed by a fierce security debate. Can genetically modified crops be eaten? Lin Min introduced that the safety evaluation process and follow-up management of genetically modified crops are very strict. When the Ministry of Agriculture accepted the application for safety evaluation of genetically modified rice and corn, it took 11 years and 6 years respectively.
Lin Min: In October 2009, the European Food Safety Agency’s GMO team gave a scientific opinion that GM corn is as safe as non-GM species in terms of impact on human and animal health and the environment. China concluded that There is no difference in the key biological nutrients between transgenic rice and non-transgenic rice. The gap between transgenic and non-transgenic rice may be smaller than that of the same rice planted in different regions. This difference is very small.
There is no absolute safety food in the world
On the one hand, it is the official scientific argument. On the one hand, it is the constant suspicion of the people. At today’s report meeting, some people suggested that if the Americans say in a few years that the long-term consumption of genetically modified foods is harmful to the human body, what should Chinese people do? After all, a lot of GM technology is currently used for rice and soybeans that Chinese people rely on to survive. Lin Min said that there has been no scientific evidence of genetically modified food and environmental safety issues. But at the same time, he also pointed out that there is no absolutely safe food in the world.
Lin Min: It will not be like pesticides, it will not be like some chemical products, including the decoration pollution we face, or the impact of this, will have no impact on future generations. First, I have to tell you that there is absolutely no safe food in the world. The varieties of soybeans you eat today have no effect on future generations. Nobody can answer you. For genetically modified species, it is the most stringent safety assessment, the most thorough research, and finally the market, if you feel unsafe, you There are options because the transgenes are all labeled.
Lin Min believes that the reasons behind the GM debate are complex, cultural, business interests, reasons for international trade, and political benefits. Transgenic technology is still in its infancy. What will happen in the future? Lin Min painted a beautiful blueprint for us.
Lin Min: The people we are doing do not feel his benefits, if one day our genetically modified technology is widely used in agriculture, industry, and environmental protection. Entering the homes of ordinary people, it was the day when the public really accepted it.
It is a single color product with extremely high color purity. It is pure in color,
