Nowadays, GMOs represent one of the main debated issues in the modern world. Every day we buy fruit and vegetables in our shops or markets, but we do not know whether they were grown using genetically modified organisms or naturally. Because today most farmers use pesticides and herbicides to grow many products. It is not yet known whether they are useful for human life or not. But we can definitely say that GMOs are harmful to agriculture. There are many reasons indicating this. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essayThe causes of the problemFirstly, the cultivation of genetically modified crops leads to violation of the circulation of substances in nature. Morrissey's research demonstrated that GM strains (subtype of a microorganism (e.g., virus, bacterium, or fungus)) from GM crops remained in the soil for years after the crop was removed. Naturally, this disrupts the interaction of substances in nature. Secondly, GMOs are also responsible for the emergence of herbicide-resistant "superweeds". This means that “super weeds” can only be killed with more toxic poisons, which ruin the soil. linked to land degradation. It is a cause of land degradation. The third reason is the growth of toxic herbicides in the soil. As a result of the growing number of toxic substances, the use of toxic herbicides such as Roundup has increased 16-fold since GMOs were introduced in “GMO Facts” (2015). All these toxic chemicals, such as pesticides and herbicides, have a negative effect on the soil. Furthermore, pesticides accumulate in the food products we can buy in our shops. Unfortunately we do not know which foreign gene is contained in the product. And this heterogeneous (incongruous) gene will probably be rejected by the organism. Another reason is the reduction of insects. Insects pollinate many of our fruits, flowers and vegetables. We wouldn't have much of our production without insect pollination services, not to mention honey, beeswax, silk, and other useful products. But the cultivation of genetically modified crops with the use of chemicals leads to mass poisoning of insects. Ultimately, we need to know that agriculture is a system with an expiration date. The consequences By analyzing the reasons listed above, we can come to admit that GMOs create many negative consequences. First of all, pesticides destroy nitrogen fixation. This can lead to a sharp decline in crop yields because the application of pesticides can destroy pollinators. A decrease in spider numbers has been reported following the application of the insecticide chlorpyrifos to grassland in the UK (2007). It is important to know that pesticides are the main cause of insect contraction. Unfortunately, herbicides don't just kill harmful insects. For example, the home range of monarch butterflies has shrunk by an alarming 90% over the past 20 years because their habitat (Mexico) has shrunk from 45 acres to just 1.7 acres between 1999 and 2013 according to Edward ( 2015). GMOs change the structure of DNA. Fungicides are toxic to soil fungi because they cause changes in microbial community structure. (Liebich et al., 20034;Pal et al.,20055). In general, GMOs also have negative consequences on the human organism, because they cause allergies and the development of diseases. According to the information.
