What is the theme of The Most Dangerous Game story?

Genetically Modified Food, refers to the transgenic biological strains obtained by using transgenic biotechnology, and the food directly made from these transgenic organisms or processed with them as raw materials. Genetically modified foods can be classified into yield - increasing type, nutritious type, ripening - controlled type, processing type and health - care type. The transgenic plant technology began in the 1970s. The United States was the first country in the world to conduct research on genetically modified foods, and the first commercially produced genetically modified food in the world was the transgenic tomato with delayed ripening, which was launched on the US market in 1994. Subsequently, genetically modified soybeans, corns, rice, potatoes, cotton, rape, etc. were produced. The International Service for the Acquisition of Agri - biotech Applications (ISAAA) reported that the planting area of transgenic crops has been continuously expanding worldwide. The global planting area of transgenic crops has increased from 1.7 million hectares in 1996 to 179.7 million hectares in 2015, achieving about a 20 - fold growth in 20 years. Hazards of genetically modified foods: they are harmful to human health, may have potential toxicity, may cause allergic reactions, and may also have antibiotic resistance risk problems. Advantages of genetically modified foods: they can reduce carbon emissions, the greenhouse effect, and the use of pesticides, protect the environment, improve the safety factor, ensure the quality of human life, and can also be used as experimental carriers to obtain test results more quickly.

First question: Can transgenic crops really increase yields? Transgenic crops cannot increase the potential yield and sometimes even lead to yield reduction. Although the yields of major crops have indeed increased in recent decades, this is mainly based on traditional breeding methods, not transgenic ones [1]. High yield is a complex genetic trait produced by the cooperation of many genes, and scientists have not fully understood how these genes cooperate yet. The existing rough technology cannot transfer high - yield genes into crops through genetic engineering, and neither can the transgenic technologies yet to be developed. Good agricultural planting methods, such as effectively maintaining soil fertility, are equally or even more important for maximizing yields. A study comparing the yields of three major crops, namely corn, rape and wheat, in the United States and Western Europe in the past 50 years found that, compared with the yields of most non - transgenic crops in Western Europe, the yields of most transgenic crops in the United States decreased and the amount of pesticides used increased. Some people think that Western Europe's reluctance to use transgenic technology has made it lag behind the United States, but the truth is that the large - scale planting of transgenic crops in the United States seems to be making the United States lag behind Europe in terms of both yield and sustainability [2]. Second question: Will transgenic crops reduce the use of pesticides? Herbicide - resistant transgenic crops are modified to survive after being sprayed with herbicides, usually glyphosate - based herbicides, such as Roundup. After spraying such herbicides, all plants in the farmland except these herbicide - resistant transgenic crops will be killed. More than 80% of the transgenic crops widely planted worldwide have been modified to tolerate one or more herbicides. Approximately 98% of commercial transgenic crops are designed to be tolerant to herbicides or contain Bt toxin insecticides (Bacillus thuringiensis insecticides) [3]. Herbicides and insecticides are strictly pesticides. Herbicide - resistant transgenic crops have led to a large - scale increase in the use of herbicides [4], [5], [6], [7], [8], [9]. Data collected by the United States Department of Agriculture showed that from 1996 to 2011, due to the planting of herbicide - resistant crops, the amount of herbicides used in the United States increased by 239 million kilograms, which far exceeded the decrease in the amount of chemical insecticides brought about by the planting of transgenic Bt crops, which was only 56 million kilograms. The total amount of pesticides used increased by about 183 million kilograms, and if the same area of land was planted with non - transgenic crops, the amount of pesticides used would be reduced by about 7% [5]. Transgenic Bt crops are not very effective even in reducing the use of insecticides. Contrary to the slight decrease in the use of chemical insecticides brought about by the planting of transgenic Bt crops, by 2007, France had effectively reduced the use of herbicides (to 94% of the 1995 level) and chemical insecticides (to 24% of the 1995 level). By 2009, the use of herbicides had dropped to 82% of the 1995 level, and the use of insecticides had even dropped to 12%. Similar trends have been seen in Germany and Switzerland, and these achievements were not achieved by planting transgenic crops [2]. The realization of these good trends has not led to a serious decline in yield per mu or farmers' income. A study conducted by French government scientists in 2011 found that through the adoption of comprehensive agricultural technologies, the use of pesticides could be reduced by 30%, while only causing a slight decline in yield (96.3% of the current level) and having no impact on farmers' income [10]. If we consider that the crop itself has become a pesticide, we can no longer say that transgenic Bt crops can reduce or eliminate the use of insecticides. The amount of insecticide carried by transgenic Bt crops is much more than the chemical insecticide they replace - up to 19 times as much in multi - resistant transgenic Bt corn. The theoretical basis of transgenic technology is derived from the gene fragments in molecular biology, which is evolved from the theory of evolution. The sources of gene fragments can be the extraction of target genes required in the genome of a specific organism, or the artificial synthesis of DNA fragments with a specified sequence. The DNA fragments are transferred into a specific organism to recombine with its own genome, and then several generations of artificial selection are carried out in the population to obtain individuals with stable and specific genetic traits. This technology can enable recombinant organisms to acquire new traits expected by people and cultivate new varieties. Commonly - mentioned genetic engineering, gene engineering and genetic transformation are all synonyms for transgenic. In 1974, Polish geneticist Walklaw Zibowski called gene recombination technology the concept of synthetic biology. In 2000, the international community re - proposed the concept of synthetic biology and defined it as gene engineering and transgenic technology based on the principles of systems biology. In 1994, the transgenic tomato Flare S A V L in the United States was approved by the US Food and Drug Administration to enter the market for sale, becoming the first transgenic food that might be sold in the world. On July 4, 2016, Russian President Putin signed a decree on that day to ban the planting of transgenic crops, the breeding of transgenic animals and the production of transgenic foods within Russia, and to ban the import of transgenic foods into Russia. Offenders will be fined. On July 26, 2019, the European Commission announced the approval of ten transgenic products to be listed on the EU market, nine of which are used as food or feed, and the other one is used as an ornamental cut flower. On December 7, 2023, the Ministry of Agriculture and Rural Affairs issued Announcement No. 732. Thirty - seven transgenic corn varieties such as Yufeng 303D and fourteen transgenic soybean varieties such as Maiyu 526. After the fourth meeting of the Fifth National Crop Variety Approval Committee, this indicates that the above - mentioned transgenic corn and soybean varieties have obtained legal status and are expected to officially enter the commercialization process. On December 25, 2023, the Ministry of Agriculture and Rural Affairs issued Announcement No. 739, approving 85 enterprises for crop seed production and operation licenses, including 26 enterprises for transgenic corn and soybean seed production and operation licenses. On January 25, 2024, the Ministry of Agriculture and Rural Affairs issued an important notice that in 2024, transgenic corn and soybean will be pilot - planted in 20 counties and cities in five provinces. The industry predicts that in about six years in the future, the planting area of transgenic corn and soybean in China will reach 40%. Genetically Modified Food/GMF refers to food produced by applying the technology of genetic engineering. It has the advantages of high productivity, rich nutrition and strong disease resistance, etc. But its defect is also apparent - it may lead to gene contamination. Thus, the safety of GMF remains a controversial topic. In China, the government and the scientific community support the promotion of genetically modified crops, but trigger a continuous trust crisis. In view of people's concern about the safety of related agricultural products, the Chinese government has drafted a new grain law, intending to impose stricter management on GMF. The law requires that no entity or individual should apply transgenic technology to the principal grain cultivars. For a rather long time, whether in the media or other information channels, there have been a large number of voices and even denunciations against genetically modified foods. Many readers lacking biological knowledge are easily frightened by the appalling statements and "scientific experimental results" in such articles. So what exactly is a genetically modified food? This issue will be translated into plain language for everyone to understand what a genetically modified food is. A transgenic organism is an organism whose genetic material has been changed in a non - natural mating and/or non - natural recombination (i.e., artificial) way. This technology is also known as gene technology or genetic engineering. Through this technology, a "good gene" fragment in one organism that meets human needs can be transferred to another organism. The food cultivated or produced using this technology is called a genetically modified food. Most of the purposes of using transgenic technology are as follows: increasing yield, improving anti - pest and disease characteristics, and improving quality or nutritional components. Example 1: Scientists have found in their research that a bacterium can produce a toxin, which has been proven to have anti - pest characteristics. Using transgenic technology, the gene that produces the toxin in the bacterium is transferred to the gene of food crops, thus improving the anti - pest ability of food crops and increasing the yield. Example 2: Mice have a strong reproductive ability and can give birth to many offspring each time. Scientists have discovered the gene with a high reproductive rate in mice and transferred this gene fragment to soybeans, thus greatly increasing the yield of soybeans and increasing the economic benefits of farmers. Objectively speaking, the answer to whether genetically modified foods are harmful is negative. The most authoritative statement should be that, according to the World Health Organization, so far there is no evidence indicating that transgenic foods are harmful to human beings. Nevertheless, many people still take a very cautious attitude towards genetically modified foods because some views advocating that genetically modified foods are harmful seem very convincing. Viewpoint 1: Genes are toxic. Actually, this view is a rather low - level and seriously misleading one and is not worth refuting. If genes are toxic, will eating pork turn people into pigs? Because pork contains pig genes, when we eat pork, we are eating pig genes. The answer is obvious. From a scientific perspective, the material basis of all genes is the same and there is no difference. They are all formed by nucleotide and base pairing. The reason for the diversity of genes is the complex order of gene arrangement. This is like a digital password. There can be countless possibilities for passwords, but ultimately they are all numbers. After humans eat food, the digestive system will decompose and metabolize nucleotides, and the genes will be destroyed and no longer exist. If genes are toxic, then all foods would be toxic, which has nothing to do with whether they are transgenic or not. Viewpoint 2: Can humans eat crops that even insects dare not eat? This actually involves a very crucial medical theory, "Talking about toxicity without considering the dose is playing hooliganism. " What insects can eat may not be what humans can eat. There are huge differences between humans and insects due to species isolation, and their sensitivities to toxicity are very different. For the highest non - toxic intake obtained from any animal experiment, when applied to humans, there will be about a 100 - fold "safety margin". The anti - pest and disease characteristics obtained by agricultural products through transgenic means are essentially the expression of proteins, and whether these proteins are toxic or how much can cause poisoning can be obtained through toxicological experiments. Currently, there is no scientific evidence indicating that such transgenic foods are toxic. There was a very confusing experiment, that is, two groups of white mice were fed tomatoes, one group was fed hereditary tomatoes, and the other group was fed non-hereditary tomatoes. The result of the experiment says that the white mice fed with transgenic tomatoes had gastric bleeding symptoms, proving that transgenic foods are toxic. But the person who wrote this report only told you half of the facts. Indeed, the mice fed with transgenic tomatoes had gastric bleeding symptoms, but at the same time, the mice fed with non - transgenic tomatoes also had gastric bleeding symptoms. This experiment was finally proven to be caused by feeding too many tomatoes and had nothing to do with whether they were transgenic or not. Such experimental results are frequently seen in reports attacking genetically modified foods. Most of them are taken out of context or only some results supporting this view are presented to readers, and readers are often unable to obtain comprehensive information, thus accepting the view that genetically modified foods are harmful. Viewpoint 3: Genetically modified foods cause cancer. Actually, the mechanism of cancer is very complex, involving environmental factors and congenital factors. These mechanisms have not been fully understood by medicine so far. But one thing can be confirmed, that is, cancer - causing factors are related to the dose. As we all know, ultraviolet irradiation can cause skin cancer. So can't we sunbathe usually? Obviously not. Summary: Whether genetically modified foods are harmful is itself an unfair debate, because logically, it seems that the harmlessness of genetically modified foods can never be proven, but to prove its harmfulness, only one harm needs to be found and confirmed. Has humanity found one so far? The authoritative statement of the World Health Organization at the beginning of this article has already given the answer. Science and technology themselves are actually neither good nor bad. We are cautious because we maintain awe of new things and need more time to understand them. But rumors and pseudo - science popularization are obviously shameful. In the information age, we have more and more channels to receive information. Because not all readers have a biological foundation, lies have become the origin of these things. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For many people who loved running, running was indeed a very happy thing. Running could bring positive effects on the body and mind, making people feel happy. From a physical point of view, running was good for the neck, shoulders, spine, heart, vision, blood, lungs, respiratory system, abdomen, knees, leg muscles, stomach, and bones. When the body gradually became healthier and stronger during the process of running, the runner could experience a sense of accomplishment and satisfaction, which was one of the sources of happiness. From a psychological perspective, running could be a way to release stress. During the process of running, people could temporarily free themselves from the various sources of stress in life, focus on their own footsteps and breathing, and relax their minds. Moreover, as the painless running method emphasized, by connecting running with imagination, music, and feelings, it could amplify the level of physical and mental pleasure while running, making the process of running full of fun. In addition, when running became a habit, just like some people saw it as a philosophy of life or a natural way of life like getting up and washing up, runners could feel their own persistence and growth in the process, which would also bring happiness. However, not everyone was suitable for running. Diabetics, patients with cardiovascular disease, patients with orthopedic diseases, pregnant women, and women on their period were not suitable for running. Running also needed to follow scientific methods, such as choosing a suitable location, weather, time, warm-up exercises before running, and focus while running. Only then could one better enjoy the joy of running. While waiting for the TV series, he could also read the exciting content related to this site!
