The authoritative academic organization China Agricultural Biotechnology Society today released the top ten rumors of genetic modification in Beijing. The turbulent genetic transformation, frequently on the Internet to upload the "single fruit are genetically modified", "the Americans never eat genetically modified" and other false news, even if the authorities repeatedly rumored also did not stop the spread of rumours. You have no tricks, take a look.
Rumor 1: Americans do not eat genetically modified foods and sell them to Chinese people.
More than 75% of foods in the U.S. market contain genetically modified ingredients.
The U.S. is a big country for the research and development of genetically modified technologies and a big country for the production and consumption of genetically modified foods. According to incomplete statistics, there are more than 3,000 types of genetically modified foods such as genetically modified soybeans, corn, rapeseeds, tomatoes, and papayas that are produced and sold in the United States, and more than 5,000 kinds of foods derived from genetically modified microorganisms such as chymosin. .
Rumor 2: GM soybeans ruined Argentine agriculture
Argentina is not "a country destroyed by genetic modification." Argentina's use of transgenic technology to make it a global agricultural exporter has brought tangible benefits to farmers.
Argentina is one of the major countries in the world that has pioneered the use of GM crops. In 2016, Argentina still maintains its ranking of the world’s third largest producer of genetically modified crops, second only to the United States and Brazil, accounting for 13% of the world's planted area. The country has planted 23.82 million hectares of genetically modified crops, including 18.7 million hectares of genetically modified soybeans, 4.74 million hectares of genetically modified corn and 380,000 hectares of genetically modified cotton.
Rumor 3: Genetic transformation leads to infertility in college students in Guangxi
The infertility of university students in Guangxi has nothing to do with genetic transformation.
The concept of abnormal semen in college students in Guangxi was based on the investigation report of the Guangxi Undergraduate Sexual Health Survey proposed by the First Affiliated Hospital of Guangxi Medical University. In the report, the investigators did not suggest that semen abnormalities are related to genetic modification. Instead, it lists factors such as environmental pollution, unhealthy living habits and other long-term Internet access.
Rumor 4: Reduction of Transgenic Rats and Sow Abortion
On September 21, 2010, the "International Herald Tribune" reported that "Shanxi, Jilin and other regions planted 'xianyu335' corn resulting in the reduction of rats, sows miscarriage and other abnormal phenomena." The Ministry of Science and Technology and the Ministry of Agriculture organized experts from multiple departments and different specialties to form an investigation team to conduct on-site inspections. According to the survey, "Xianyu 335" is not a genetically modified variety, and Shanxi, Jilin and other places have not been planted with genetically modified corn. The reduction in rats and sows' miscarriage are not related to genetic transformation. This is a false report. The "International Herald Tribune" report was named "2010 Top Ten Scientific Rumors" by The Beijing News.
Rumor 5: Genetically Modified Food Affects Future Generations
Modern science has not found a case where the integration of genetic material into the human body through the transmission of genetic material, the phenomenon of eating genetically modified foods affecting future generations is completely alarmist.
Human food has been used for tens of thousands of years as food for plant and animal origin. These natural foods also contain various genes. From a biological point of view, the exogenous genes of genetically modified foods are the same as those contained in ordinary foods. Digestion and absorption by the human body and consumption of genetically modified foods cannot change human genetic characteristics. In fact, even the most traditional animal and plant foods that people eat often contain tens of thousands of genes. It is impossible and unnecessary to worry that genes from animals, plants and microorganisms in foods will change people’s Genes are passed on to future generations.
Rumor 6: The cherry tomatoes, purple sweet potatoes, and color peppers currently on the market are all genetically modified varieties.
At present, cherry tomatoes, purple sweet potatoes, and color peppers that are sold on the market in China are not GM varieties.
Plants are a valuable asset endowed by nature to human beings. Humans have cultivated and domesticated wild plants in long-term farming practices, thus forming a rich variety of crops. All cherry tomatoes, purple sweet potatoes, and color peppers on the Chinese market are naturally evolved and artificially selected.
Transgenic products can be divided into two categories: one is China's own planted and produced transgenic insect-resistant cotton and transgenic anti-virus papaya; the other is imported from abroad, genetically modified soybeans, genetically modified corn, genetically modified rape, genetically modified sugar beets and genetically modified cotton It is mainly used as raw material for processing.
Rumor 7: Genetically modified foods cause cancer, leading to infertility
It is safe to approve the listing of genetically modified products through scientific evaluation.
To ensure the safety of genetically modified products, the Codex Alimentarius Commission, the UN Food and Agriculture Organization of the United Nations, and the World Health Organization have developed a series of standards for evaluating the safety of genetically modified organisms and have become globally accepted evaluation criteria. In accordance with these evaluation criteria, countries have formulated corresponding evaluation norms and standards. From the perspective of scientific research, many international professional organizations have already had authoritative conclusions on the safety of genetically modified products. It is safe to pass the approved genetically modified products. From the perspective of production and consumption practices, over 20 billion mu of cultivated GM crops have been planted over the past 20 years, and no confirmed GM food safety incidents have been found. Therefore, genetically modified products that have undergone safety evaluations by scientists and the government has rigorously approved are safe.
Proverb 8: Insect-resistant GM crop worms will die and be harmful to humans
In fact, insect-resistant transgenic crops are not harmful to humans.
The Bt protein in insect-resistant transgenic crops is a highly specific pesticidal protein that binds only to specific receptors in the intestinal epithelial cells of lepidopteran pests such as the cotton bollworm, causing intestinal perforation, resulting in the death of pests, while others Insects, mammals and human intestinal cells do not have binding sites for the Bt protein and therefore do not cause harm to other insects and mammals, and do not affect human health.
In addition, humans have discovered Bt protein for 100 years, and Bt preparations have been used as bioinsecticides for more than 70 years. There have been no reports of allergic reactions caused by Bt preparations.
Rumor 9: No increase in production of transgenic crops, no effect on production
The effect of increasing the yield of transgenic crops is objective. At present, GM crops that are widely grown commercially are not directly targeted at increasing production. GM crops with higher yields and other better characteristics are the next generation of genetically modified crops.
Whether or not agricultural production is affected by many factors, transgenic insect and herbicide-resistant varieties can reduce pest and weed damage, reduce yield loss, accelerate the promotion of less tillage and no-tillage cultivation techniques, and actually increase production. . For example, in Brazil, Argentina, and other countries, the production of GM soybeans has increased significantly; after South Africa has promoted the cultivation of transgenic insect-resistant maize, the yield has doubled, from a maize importing country to an exporting country; after India introduced a transgenic insect-resistant cotton, Cotton importers have become exporters.
Proposal 10: Planting Transgenic Herbicide-Resistant Crops Produces "Super Weeds"
Transgenic herbicide-tolerant crops do not become uncontrolled "super weeds."
In 1995, rapeseed plants in Canada were found to be resistant to 1-3 herbicides in some rape plants. Some people called it "super weeds." In fact, this rape can be completely killed after spraying another herbicide 2,4-D. Actually, "Super Weeds" is just a figurative metaphor. At present, there is no evidence to prove the existence of "super weeds".
