1. Changing the environment: There are still many differences between genetically modified foods and non-genetically modified crops in the process of planting and growing, which will have certain impacts on the soil and the surrounding ecological environment, and this impact is not necessarily positive.
2. Pest escalation: Genetically modified food itself has the gene to kill pests, but pests can rely on elimination and evolution to produce higher resistance to this characteristic, which may lead to pesticides being unable to kill.
3. Reduce non-GM crops: GM crops are cheap, with good varieties and high yield. Therefore, many farmers are willing to plant genetically modified crops. For example, in the northeast of the traditional non-GM soybean producing area, local soybeans are decreasing year by year and replaced by GM soybeans. This situation is likely to lead to the suspension and extinction of non-GM crops.
4. Psychological panic: Even if genetically modified foods have no physiological harm, normal people still tend to choose non-genetically modified foods when choosing foods. Therefore, if they eat genetically modified food for a long time and know it, it will cause a certain psychological burden and produce psychological diseases.
Extended data:
Some people think that eating genetically modified food will cause cancer and sterilization, and planting genetically modified crops will lead to land abandonment. In this regard, the Dean of the College of Food Science and Nutritional Engineering of China Agricultural University said that these are false statements that have been repeatedly hyped and have been clarified many times before.
The European Food Safety Agency completely denied the experiment of French professors feeding genetically modified corn to mice to create tumors. The statement that the areas where genetically modified oil is consumed in China are concentrated areas of genetically modified diseases was denied by medical experts at that time because there was no epidemiological investigation. It has long been clarified that the cultivation of genetically modified crops in China has led to land abandonment.
In fact, the soil fertility in China's transgenic cotton planting areas is stable and the yield is normal. It is a rumor that eating genetically modified food will lead to "sterilization", because Guangxi has never planted and sold genetically modified corn, and Dika corn is not a genetically modified variety. The rumored "Investigation Report on Sexual Health of Guangxi University" does not involve genetic modification at all.
People's Daily Online-If sterilization caused by genetically modified foods is unreliable, we still need to guard against four major hazards.
