In fact, in a broad sense (that is, genes have changed), all organisms that can be seen by the human eye are genetically modified, because the original life form is single-celled organisms, and the human eye cannot see single-celled organisms. The prerequisite for the change of biological form is the change of genes.
There are four preconditions for the change of biological morphology: natural evolution, artificial hybridization, radiation mutation and transgenic technology. Among them, the new species produced by natural evolution, artificial hybridization and radiation mutation are random and uncertain, and it is necessary to obtain successful new species through natural selection or artificial breeding. Only transgenic technology can accurately cultivate new varieties with people's expected new traits through surgical precise changes in biological genes.
The main reason why the West opposes transgenic technology is that the theocracy defeated human rights in the west after the failure of the reform of King Akhenaton of the 18 dynasty in the new kingdom of Egypt, forming a social form of divine monarchy. God has become the master of the world above, and man is only the slave of God. Many things can only be done by the master, but not by the slave. For example, it is God's privilege to create species. But transgenic technology can enable human beings to transform nature instead of God. This is totally unacceptable to those pious god servants and resin slaves.
People who oppose transgenic technology in China are mainly bewitched by anti-China forces in the West. They are worried about food safety in three aspects: first, genetically modified biological products are harmful to health; second, genetically modified biological products will lead to infertility; and third, genetically modified biological products will lead to foreign DNA invading the human body. In fact, these are all problems that need not be worried at all.
Genetically modified biological products will only do harm to health in two situations, one is that Dr. Evil did it on purpose, and the other is that Dr. Er Gang made mistakes in operation. Faced with this risk, China has a strict review system for genetically modified organisms before they enter the circulation. For example, imported genetically modified organisms must be circulated in the country of invention and the third country for a certain number of years without bad records, etc. There is a strict supervision system in the process of entering the circulation. For example, once the "golden rice" incident in 20 12 was discovered, China CDC immediately launched a comprehensive investigation, and Yin Shi 'an and other responsible persons were dealt with and compensated.
It is a misunderstanding that genetically modified organisms can lead to infertility. First of all, genetically modified organisms are only produced in the laboratory for the first generation, while the offspring are bred by the previous generation, not every generation comes out of the laboratory. That is to say, the species cultivated by transgenic technology are also reproductive. Secondly, even eating infertile species will not lead to infertility. For example, infertile mules, seedless watermelons, etc. are our regular food sources and do not cause infertility.
There is no need to worry about the invasion of foreign DNA into the human body. First, the human body actually has less than half of its own DNA, and there are a lot of foreign DNA in itself, such as the DNA of beneficial bacteria in the intestine, which does not belong to human beings. In addition, there are foreign DNA in every cell of the organism. Many scientists believe that mitochondria and chloroplasts in biological cells originated from bacteria and cyanobacteria born in primitive eukaryotic cells respectively. Second: non-GMO organisms also have DNA, and eating non-GMO products will also ingest foreign DNA. Third: DNA cannot pass through the digestive tract wall.
Therefore, as long as the relevant departments earnestly perform their duties, there is absolutely no need for us to worry that eating genetically modified biological products will harm us.
