-compatriots, for our future generations and the future of the Chinese nation, reject genetically modified food! ——
1997 german farmer krone began to plant Syngenta Bt- 176 corn experimental field. In the first three years, corn grew well and there were no pests. 200 1 when he fed the corn to the cows, the cows began to have severe diarrhea and stopped producing milk. Finally, he lost 70 cows.
1In the autumn of 998, Professor Puztai of the Lovett Institute in Scotland publicly declared on TV that his experiments proved that the kidneys, thymus and spleen of experimental mice grew abnormally or atrophied or grew improperly, the brain shrank, many important organs were destroyed and the immune system weakened.
1999, John Losey, a researcher at Cornell University in the United States, published a report in the British magazine Nature, feeding butterflies with leaves coated with Bt transgenic corn pollen, resulting in 44% larvae death.
1997- 1998, experiments in Britain and other countries found that genetically modified foods caused some abnormal animal health and abnormal planting areas. Studies funded by the British government show that mice eating genetically modified potatoes have early symptoms of liver cancer, testicular hypoplasia and partial atrophy of immune system and nervous system.
1998, EU countries passed laws to strictly restrict the operation of genetically modified agricultural products in laboratory environment or closed areas.
In 2004, the transgenic Bt- 176 corn developed by Syngenta broke the scandal. Farmers in northern Hesse, Germany, began to plant Bt- 176 corn from 1997 and used it as supplementary feed for dairy cows. In 2000, when farmers began to increase the proportion of this corn in the feed, all the cows died. In 2004, Professor Herbik of the Institute of Kicking Botany of Swiss Federal Institute of Technology found that the Bt toxin used to kill the European corn borer in Bt- 176 could not be decomposed, and eventually poisoned the cows.
On May 22, 2005, the British Independent also disclosed a report by Monsanto, a well-known biotechnology company, saying that rats fed with genetically modified food had organ variation and blood composition changes.
On June 165438+ 10/6, 2005, a research report published by CSIRO showed that a four-week experiment showed that mice fed with genetically modified peas developed inflammation in their lungs, and mice developed allergic reactions, which made them more sensitive to other allergens and stopped 10 years accordingly.
In 2006, the higher nervous activity of Russian Academy of Sciences and Irina? Dr almakova's research found that more than half of the young mice who ate genetically modified soybeans died in the first three weeks after birth, which was six times that of the young mice who did not eat genetically modified soybeans.
In 2007, with the financial support of the Austrian government, Professor Zetek and his research team conducted experiments on the hybrid of transgenic corn NK603 (herbicide-resistant) and transgenic corn MON8 10 (Bt-resistant) developed by Mondushan Company. After 20 weeks of observation, it was found that transgenic products affected the reproductive ability of mice.
In 2008, Italian scientists conducted a long-term experiment. They fed glyphosate-resistant genetically modified soybeans to female mice for 24 months and found that the livers of female mice who ate genetically modified soybeans were abnormal.
In June, 2007, 5438+ 10 and June, 5438+065438+ 10, new york Times and other media reported that after long-term and meticulous follow-up, it was found that two kinds of genetically modified corn planting did harm to the survival of butterflies, and the threat to ecological environment safety exceeded the acceptable level. To this end, the EU has initially decided to ban the sale and use of genetically modified corn seeds.
In 2007, French scientists confirmed that a genetically modified corn produced by Monsanto was toxic to human liver and kidney.
In 2008, American scientists also confirmed that long-term feeding of genetically modified corn would damage the immune system of mice, and the research results were published in the Journal of Agricultural and Food Chemistry in the same year.
On February 22, 2009, 65438+, the French Biotechnology Committee finally announced that "the disadvantages of genetically modified corn outweigh the advantages", which is equivalent to permanently abolishing genetically modified crops in France.
The research results published in the International Journal of Biological Sciences from June 5, 2008 to February 2009 showed that three kinds of genetically modified corn from Monsanto could damage the liver, kidney and other organs of mice. Three genetically modified corn varieties, one of which is designed to resist broad-spectrum herbicides (so-called glyphosate-resistant herbicides), and the other two contain protein from bacteria, have pesticide characteristics. This study uses Monsanto's own raw data.
On July 28th, 2004, the National Academy of Sciences of the United States completed a special study and released a research report, pointing out that genetically modified foods will cause unpredictable damage to the host DNA, which cannot be found by the existing auditing and monitoring system of American government agencies. The National Academy of Sciences listed the anomalies that were not found during the review of genetically modified foods:
—— Mice that have eaten genetically modified foods such as genetically modified corn have abnormal blood cells and hepatocytes, and their livers are heavier than those that have never been eaten;
-Pigs that have eaten genetically modified corn have false pregnancy or infertility on farms in the Midwest of the United States;
-Abnormal death of dairy cows eating genetically modified corn feed in German experimental farm;
-The mortality rate of chickens using genetically modified feed is twice as high as that using natural feed;
-after the emergence of genetically modified soybean food in the British market, residents' allergies increased by 50%, and the same situation occurred in Brazil;
-Genetically modified corn, which has long been considered "safe", is not as effective as the promoters say. For example, the skin, small intestine and respiratory system of Filipino consumers have abnormal reactions;
1997- 1998, experiments in Britain and other countries found that genetically modified foods caused some abnormal animal health and abnormal planting areas. Studies funded by the British government show that mice eating genetically modified potatoes have early symptoms of liver cancer, testicular hypoplasia and partial atrophy of immune system and nervous system.
From 2000 to 200 1 year, it was further confirmed that the ecological environment in transgenic planting areas was abnormal. For example, there is no abnormality in the transgenic corn varieties themselves, but the wild ecological environment around them is abnormal, while the field tests of transgenic sugar beet and other varieties show that they are abnormal in themselves and their environment. To this end, the agricultural departments of the governments of the United States, Canada, Britain and the European Union urgently set up a working group on agricultural ecological environment protection and began to closely monitor the genetically modified planting areas around the clock.
A survey in Dafeng City, Yancheng, the "hometown of cotton" in Jiangsu Province, found that the quality of transgenic cotton also declined seriously after the fifth year of promotion in this province, and its performance was not as good as that of ordinary cotton.
Nature, an authoritative British scientific magazine, published a paper by Professor john rossi of Cornell University in the United States. It is pointed out in the paper that beneficial insects in farmland, such as butterfly larvae, eat leaves sprinkled with some transgenic corn pollen, which will be stunted and have a particularly high mortality rate.
A kind of "Xinglian" transgenic corn produced by Avandis Company, because it may have allergic reaction to human body, the US Environmental Protection Agency only approved it for animal feed and prohibited it from being used in food production.
Mayeno, A.N. et al. (1994) reported a new disease of unknown cause, mainly manifested as eosinophilic myalgia. Clinical manifestations include paralysis, neurological problems, pain and swelling, itchy skin, heart problems, memory loss, headache, light sensitivity and emaciation (Brenneman, D.E. et al.,1993; Love, L.A., etc., 1993). It was later discovered that tryptophan was produced by genetically engineered bacteria born in a Japanese company. Three months later, the eater fell ill, resulting in 37 deaths, 1, 500 people were partially paralyzed, and more than 5,000 people were occasionally weak. According to the determination, the content of 0. 1% can kill people.
The long scientific investigation report issued by the National Academy of Sciences clearly points out that more and more observations and discoveries prove that the planting and use of genetically modified crops pose a potential safety threat to animals and the ecological environment; It is necessary to implement compulsory isolation measures in the planting areas of genetically modified crops, and implement stricter control and testing and monitoring of genetically modified foods.
Greenpeace, an international environmental organization, also expressed great concern. Transgenic rice may pollute traditional rice varieties through pollen transmission, posing a serious threat to the environment and biodiversity.
Who advocates being cautious about the development of genetically modified foods, especially the introduction of genetically modified products that have not been strictly tested abroad.
