Who can help me make a PPT about the harm of genetic modification?

The American press released that genetically modified organisms are the public enemy of human beings and genetically modified organisms: the bottom line of the United States.

Harm to human health In May 2009, the American Academy of Environmental Medicine issued a report saying: "Some animal experiments show that eating genetically modified food has serious health risks, including infertility, immune problems, accelerated aging, insulin regulation and changes in major organs and gastrointestinal system." The conclusion reached by the Institute of Environmental Medicine of the American Academy of Sciences caused a sensation. After the release of the report, the US Department of Health also published a scientific paper at the end of 2009, pointing out that genetically modified foods will cause harm to internal organs. According to the research report of the National Science Foundation of the United States, most people are negative and skeptical about genetic modification.

In fact, as early as 2008, American scientists confirmed that the immune system of mice fed with genetically modified corn for a long time would be damaged, and the research results were published in the Journal of Agricultural and Food Chemistry in the same year. In April of the same year, the FDA, the department in charge of food and medicine of the US government, announced the revocation of the industrial guide for planting CRY9C transgenic corn released several years ago. One of the main reasons is that genetically modified crops pose a serious threat to human health and safety. After consulting more than 600 scientific journals, Pushpam Barga, a world-renowned biologist, concluded that genetically modified organisms are a major factor in the rapid deterioration of American health.

At least ten kinds of super weeds are rampant in at least millions of hectares of farmland in 22 States of the United States. The common feature of these farmland is that they all planted genetically modified crops and used Monsanto's patented herbicide "Nongda". "The grass that we used to kill without a drop of pesticide has now been genetically modified into a super big grass that is invulnerable to all pesticides." Anderson is a farmer in western Tennessee, USA. Since last year, he began to have a headache for a weed called amaranth. This kind of grass can grow seven or eight centimeters a day, and the tallest can grow to more than two meters, covering all the crops under it and not seeing the sun. This dense weed is very strong, and harvesters are often damaged by it.

Super pests also appeared in genetically modified farmland in the United States. Because transgenic crops are not aimed at secondary pests, some secondary insects have gradually become the main pests of crops. Insecticides make these pests resistant to drugs and become super insects. Although farmers put in more drugs to control pests, it still didn't help. The National Academy of Sciences said: Long-term practice has proved that 20% of farmland needs to be interplanted with similar natural crops to make pests "have food" and prevent them from becoming antibody "super pests". In other words, transgenic crops not only failed to prevent pests, but also made pests that were originally small pests become "super pests".

The fact that the United States covers up the harm of genetically modified foods is that as early as the early 1990s, the US Food and Drug Administration (FDA) has already warned the safety of genetically modified foods: genetically modified foods are inherently dangerous and may cause undetectable allergies, new diseases and nutritional problems. It urged the relevant departments of the US government to conduct strict long-term tests. However, the White House ordered the agency to promote the development of biotechnology.

The United States should set its own safety bottom line for genetically modified crops, but it is worth noting that no matter how to support the development of genetically modified crops, the US government has always had a bottom line from the beginning of developing genetically modified crops: preventing genetically modified crops from invading the existing natural agricultural production system and natural food supply system. The area of natural farmland in the United States far exceeds that of genetically modified farmland, which is mostly newly reclaimed farmland far away from natural agriculture and isolated from the world.

American laws and regulations clearly point out that in order to ensure that the United States has sufficient quality and quantity of natural farmland strategic reserves, that is, once it causes great harm and has to abandon genetically modified crops and existing farmland, the United States still has enough natural farmland to feed all American residents.

Even more frightening is Epicyte, a biotechnology company in San Diego. In September of 20001year, the company announced the creation of the ultimate version of genetically modified corn-contraceptive corn, which is a great contribution to the world population problem.

Please pay special attention to this contraceptive corn, which is naked and openly used for sterilization and extinction of all animals! It is a super strategic weapon to exterminate the population! This special weapon directly used to exterminate the population was born ten years ago! In the past ten years, all kinds of genetically modified crops have played a common role-that is, the destruction and extinction of life! Irreversible destruction of the ecological balance of nature!

Animal experiments by Russian scientists have confirmed that animals will be extinct for three generations after eating genetically modified food.

(Linked article: "[Reprinted] Russia confirmed: Genetically modified animals have been extinct for three generations") In 2006, Irina, a scientist at the Institute of Advanced Neuroactivity and Neurophysiology of the Russian Academy of Sciences? 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.

Studies funded by the British government show that mice eating genetically modified potatoes will have early symptoms of liver cancer, testicular hypoplasia, partial atrophy of immune system and nervous system and other abnormal phenomena.

After farmers planted transgenic Xianyu 335 corn in Yuci area, Jinzhong City, Shanxi Province, the mice in the field and at home disappeared.

In May this year, the reporter visited eight villages in Jinzhong, which further confirmed what Liu Min said about the abnormal situation of animals, and found another strange thing in the local area: sows gave birth less, and there were many cases of infertility, false birth and abortion. Zhang, a villager, has been raising pigs for nearly 10 years. He said that in the past, more than 20 sows in his family could produce at most 16 pigs, and never less than 10 pigs. That is, four years ago, he found that sows gave birth to fewer and fewer piglets. There are also some born piglets that look healthy, but they died before Tayo was born.

In addition to mice and pigs, the reporter also found abnormal situations in sheep and dogs in Jinzhong. A professional sheep farmer in Yangcun said that in the past, ewes could give birth to two or three at a time, but now there is only one, at most two. A dog dealer also chatted with reporters that dogs often have liver ascites or kidney ascites now, and there is always a lot of water when laparotomy is performed. .

China male fertility decline: nearly 40% of men have poor sperm quality and abnormal semen!

Analysis of semen quality of volunteers from Guangxi 19 University 2 17 University showed that 56.7% of college boys had abnormal semen quality!

Chongqing: 20 boys from a university in our city met at the Male Fertility Monitoring Center of the Municipal Family Planning Association. As a result, half of them failed in semen!

The first sperm bank in Zhejiang Province recently revealed that 86% of the sperm collected by the bank in the past year were unqualified!

Henan: Henan human sperm bank, which has been running for one year, recently received shocking news: 80% of the semen donated by college students as the main donor is unqualified!

At present, foods and genetically modified foods sold in supermarkets in the United States can be unmarked, but natural foods or ingredients are natural raw materials, but a green food can be marked in a prominent position. Americans basically only buy green food in supermarkets. The same supermarkets mainly sell green food, and few people buy those without green food signs. Because the proportion of food consumption is extremely low relative to the income of Americans, the standard of green food eaten by ordinary Americans is even stricter than that specially supplied by China.

This is the reason why American athletes don't eat the food provided by China Olympic Village in Beijing, and this is the difference between developed and developing countries.
