1. There is no knowledge about the harm of genetic modification in the world, but everyone should understand it and promote it to some extent. Food is a very important thing, and all countries don't want to leave the lifeline to the United States, but all countries can't keep up with the expansion of American transgenic technology. Passive acceptance can also understand where its harm lies. On the one hand, they also increase their own research on genetic modification and realize product patenting.

2. It should be said that the genetically modified seeds planted all over the world have not brought obvious disadvantages to countries at present, but they may not be seen in the long run. Once American companies control the global market, they will have to obey him. Maybe in a few years, the United States will buy seeds of harmful genes for people in other countries to eat. This is everyone's concern.

I don't think this worry is necessary. The development of human rights in today's society, if the United States has such an attempt, will certainly lead to riots all over the world. Global mobility makes genetically modified foods appear on the dinner table of American friends. This must be a world war. Without the so-called garbage population, there would be no elite. Now scientists don't need to do this when they get there. They can directly improve their genes through technical means.
