The U.S. GM technology has turned and is changing from a challenge of natural and natural development to a framework of “respecting nature†and “subject to natureâ€.
“We used to use less than a drop of pesticide to kill the grass. Now it has been transformed into a 'supergrass' that is incapable of all pesticides.†Anderson is a farmer in western Tennessee, and since last year, he has started A kind of weed headache called Longmania.
This kind of grass can grow 7-8 centimeters a day. Its maximum energy can grow to more than two meters. The crops are all covered underneath, and there is no sunlight. This stout weed is very strong and harvesters are often damaged by them.
No fewer than ten "super weeds" are raging in at least one million hectares of farmland in 22 states of the United States. The common feature of these farmlands is that they have planted genetically modified crops and have used Monsanto's (Agricultural Bio-Chemical) company's “Rongda†patented herbicides.
Nowadays herbicide-fed herbicide-resistant weeds are full of farmland and farmers are forced to spray more toxic herbicides. Unfortunately, all the herbicides are useless for this super weed. Monsanto said that it will take six years to develop herbicides against these mutated weeds.
Farmers cannot wait six years. In order to eliminate weeds, they tried their best, or simply weeded by hand. After the cost of investing hundreds of thousands of dollars was still ineffective, many farmers chose to give up. Super weeds are spreading in genetically modified areas, and some of the cultivated land has been forced to desert.
In the United States, genetically modified crops are taking off myths. American scientists say that genetically modified crops are not as beautiful as they were originally thought of, and that there is no such thing as a GMO company promises.
Doctors suggest avoiding genetically modified foods
The U.S. comprehensive reflection on transgenes began last year and climaxed in recent times.
In May 2009, the report launched by the American Academy of Environmental Medicine caused a sensation. The report strongly recommends that genetically modified foods pose a serious safety threat to patients, call on members' doctors not to allow their patients to eat genetically modified foods, and educate the community's population to avoid eating genetically modified foods.
"Some animal experiments have shown that eating genetically modified foods has serious risks of damaging health, including infertility, immune problems, accelerated aging, insulin regulation and changes in major organs and gastrointestinal system," concluded the Institute of Environmental Medicine, US Academy of Sciences Yes, "The relationship between genetically modified foods and the adverse effects of health is not related to it, but there is a causal relationship."
“More and more doctors have already prescribed a prescription for non-GM foods (to patients).†World-renowned biologist Pushpalmi Balgar concluded after reviewing more than 600 scientific journals: GMOs are the United States. A major factor in the rapid deterioration of human health.
Regarding the principle of genetic modification, the Institute pointed out that the genes inserted into the genetically modified soybeans will be transferred to the DNA of the bacteria that lives in our intestines and continue to function. This means that after eating, although we do not eat genetically modified foods, we continue to produce potentially harmful genetic proteins in our bodies. "To be thorough, eating GM corn will transform our intestinal bacteria into living pesticides. Factory, probably until we die."
After the report was released, the U.S. Department of Health published a scientific paper at the end of 2009 that indicated that GM foods can cause harm to the viscera. According to the research report of the National Science Foundation, most people have negative attitudes and doubts about genetic modification.
In the United States, genetically modified foods are not labeled, but officially certified non-genetically modified foods, that is, natural and organic foods will be clearly labeled.
Data from the U.S. Department of Agriculture showed that the retail sales of organic food in the United States rose from 3.6 billion U.S. dollars in 1997 to 211 billion U.S. dollars in 2008. Despite the economic recession in the United States, the organic market has been booming and has led to periodical organic products. shortage.
Super Cordyceps makes government change
In addition to health, the troubles caused by GM crops to agriculture have also attracted the attention of academics and government departments.
In April this year, the US National Academy of Sciences released the report “Impact of GM Crops on the Sustainability of U.S. Agricultureâ€, pointing out that the weed issue that has caused peasants' distress points out that the planting of GM crops does not eliminate weeds. Instead, the use of herbicides continues. Rising, threatening environmental security.
In addition to super weeds, superbugs have also appeared in GM farmland. Since GM crops are not targeted at secondary pests, this makes some secondary pests a major pest of crops. Insecticides have made these insect pests resistant to insect pests and become super bugs. Although farmers have invested more drugs to control insect pests, they still do nothing.
The National Academy of Sciences said: The long-term practice has proved that the so-called pest-resistant genetically modified crops need to be planted with 20% of the same natural crops in order to allow pests to “eat†and avoid them becoming “super pests†of antibodies. In other words, GM crops have not been able to prevent pests but instead have caused pests that were originally small pests to become “super pestsâ€.
The report of the National Academy of Sciences uses 16 years of practical facts and statistical data to make it clear that the long-term cultivation of genetically modified crops will bring unrecoverable side effects to the agricultural economy.
The US Department of Agriculture, which has consistently maintained that American farmers have benefited from the cultivation of genetically modified crops, has finally changed its position. The latest statistics from the US Department of Agriculture acknowledge that after planting genetically modified crops, the cost of fuel for agricultural operations has more than doubled and the amount of pesticides used has exceeded natural levels. Crop planting and seed costs have also increased significantly.
The most obvious game took place between the U.S. Department of Justice and Monsanto and other seed companies. In April of this year, the U.S. judicial authorities intervened to review the legality of Monsanto and other companies that closed the market for genetically modified data. This is the first time that the US judicial department has been involved in the management of genetically modified technology.
All along, GM manufacturers have used patent rights to prohibit any other person or organization from “opening up†their genetic data. Whether it is testing or technical improvement, if someone or a laboratory organization wants to “open up†a genetically modified data, it must obtain permission from the owner of the data patent beforehand.
However, this time, the GM company lowered its head. In the game with the U.S. government agencies, the gains of GM companies that have been at the forefront have begun to weaken.
New technologies are natural
U.S. media believe that the U.S. government has clearly stated that the cultivation and application of the first generation of genetically modified crops poses a serious threat to human health and ecological environment. If we do not change our thinking and practices right away, it is very likely that GM technology will die.
In fact, seed companies such as Monsanto and DuPont have already sensitively felt the subtle changes in the official attitude of the United States and the people’s resistance to doubts.
On June 8th, DuPont announced that its "new-generation genetically modified" soybean developed by its subsidiary has been approved by the US Department of Agriculture and the US Food and Drug Administration (FDA), and will be listed approximately in 2012. The company announced that: This is a "milestone" development, marking the development of genetically modified crops really entered the "environmentally friendly" and "safeguard the health" of the development stage.
Subsequently, Monsanto responded by saying that it would launch "a new generation of genetically modified" soybeans and other crops.
It is understood that the idea of ​​“a new generation of transgenics†is very different from that of the first generation of transgenics. Instead of implanting foreign genes, it shuts down or suppresses certain genes that may cause problems. The "new generation of transgenics" uses gene silencing techniques.
The American academic community uses an analogy to illustrate this gene silencing technique: if parents have a certain genetic disease, through genetic silencing techniques, the genetic genes of those diseases are in the "closed" or "silent" state in the child's body, thereby achieving the purpose of health care, This will not change the natural genetic structure of the human body.
Obviously, the United States has shifted its GM technology and is now shifting from challenging natural and natural development ideas to the framework of “respecting nature†and “subject to natureâ€.
