The Chinese have always been sensitive to genetically modified technology. Many people do not eat genetically modified vegetables and feel that it is potentially dangerous. Although many people take the initiative to avoid genetic modification, genetic modification technology is constantly approaching us.
Recently, the United States approved the production of genetically modified mosquitoes to curb the number of mosquitoes in nature. Many netizens worry whether genetically modified technology will be weaponized?
by British Biotechnology Transgenic mosquitoes manufactured by Oxitec (Company O)Through hybridization with mosquitoes in nature, the natural population of wild mosquitoes will be extinct, thereby reducing the number of local mosquitoes.
Although this technology has shown its effect in the laboratory, experts warn that the program may make mistakes in the field. After all, nature is not as ideal as the laboratory.
Scientists who support this technology said: “The release of genetically modified mosquitoes is related to the potential benefits of hundreds of millions of people threatened by mosquitoes. "
Scientists who oppose this technology said: "But there are reasons to worry that the current scientific evaluation of genetically modified mosquitoes is not enough, and the supervision of their release is not in place, and problems may arise. "
Although scientists are still arguing, the U.S. Environmental Protection Agency has approved the experiment in May and the experimenters will release genetically modified mosquitoes in Florida and Texas.
Starting this summer, in the next two years, O company will release millions of Improved male mosquitoes. These mosquitoes will mate with wild female mosquitoes, and their female offspring will die. In other words, without the female mosquitoes that give birth, the local mosquito population will be extinct.
Only female mosquitoes Will bite humans, which means that genetically modified male mosquitoes will not affect humans. Over time, the wild population of mosquitoes collapses, which may save thousands of lives.
However, ideals are beautiful , But this planHowever, the implementation of the census is troublesome. Scientists worry about the lack of supervision of the mosquito release projects in Florida and Texas.
This company has A batch of genetically modified mosquitoes were released in Brazil.Often obvious, but after a period of time, nature’s protective mechanisms are activated, creating a super-resistant mosquito that is harder to kill than before.
As early as 2012, environmentalists said: "Lack of a comprehensive assessment of the natural environment, human health, and moral hazards. In this case, the release of genetically modified mosquitoes is extremely irresponsible."p>
"Company O values their own interests and does not care about humans and the natural environment. They produce the first batch Genetically modified mosquitoes were released in an archipelago without biosafety laws or regulations. This is an irresponsible behavior."
The concerns of environmentalists are not unreasonable. First of all, O company is really famous. It's not good. In order to realize profit early, natural experiments are carried out everywhere, but they don't even know what the consequences will be. They can only find some backward areas to be guinea pigs.
But even so, it cannot be said that other humans are not in danger. After all, the world is now connected as one There is a problem in a country, and no country can do it alone.
Secondly, since genetically modified mosquitoes can carry genes that exterminate wild mosquitoes, after modification, can they also carry genes that are harmful to humans? This is one thing. A genetic weapon with great lethality.
Before fully understanding the risks of genetically modified technology, such experiments should be cautious.p>
What do you think of the release of genetically modified mosquitoes in the United States?
