Genetically Modified Crops

For centuries farmers have planted crops for certain desirable characteristics. Genetic engineering provides a faster and more accurate way to achieve the same goal, in their twenties, not in their twenties. Transgenic (GM) crops increase yield, increase nutritional value, extend shelf life, resist drought, resist frost and pests. Examples of genetically modified crops include corn cultivars containing bacterial insecticide genes that kill larval pests, and soybeans with genes that make them resistant to weed insecticides such as Roundup. The "nutrition-enhanced" GM crop that is being developed includes gluten-free wheat varieties, the main cause of food allergy, vegetables with a higher vitamin E level, to help fight heart disease, and "golden rice" It is genetically engineered Vitamin A and iron are included to prevent general nutritional deficiency in developing countries. In the United States, GM corn is used for many common foods such as corn flower, tortilla chips, high fructose corn syrup (sweetener of soft drinks and baked goods). In 2010, more than 80% of corn, soybeans, cotton and sugar beet from the United States are genetically modified. Regulation of genetically modified foods in the United States is based on this product, but the European Union (EU) regulation is based on this process. Therefore, the European Union regulates genetically modified animals and plants more precisely, European masses are paying attention to GM foods. Internationally, the cultivation of GM crops is expected to increase from six countries in 1996 to 25 countries in 2009, reaching 40 countries (mainly developing countries) by 2015. In 2009, about 134 million hectares of land are cultivated through GM crops throughout the world.
In addition to potential food safety risks, critics of GM crops are also concerned about potential harmful ecological effects.
First, when genetically modified crops are mated with wild relatives, foreign genetically modified organisms can "contaminate" the natural ecosystem. For example, it is known that pollen of Bt corn is applied to crops other than Bt. This genetic contamination can cause problems for certified organic agricultural producers and certain US trading partners.
Secondly, some ecologists are warning about the adverse effects of Bt corn on non-target insects such as Butterfly butterfly to wild spruce growing near the corn field 3. However, we need to do research for a longer period of time.
One of the most famous and controversial uses in genetic engineering is the production of genetically modified foods through the creation and use of transgenic crops or transgenic livestock. Crops were developed for increased crop yields, improved tolerance to abiotic stress, changes in the composition of foods, or for the production of new products. The first commercially large scale crops provided protection against pests or resistance to herbicides. Fungal and antiviral crops have also been developed or under development. This makes it easier to manage crop insects and weeds and indirectly increase crop yields. We are also developing GM crops that increase direct yield by promoting growth or improving salt tolerance (by improving salt tolerance, cold resistance, and hardness resistance). In 2016, the squid was genetically engineered with growth hormone, and it reached the usual adult body shape quickly.
Genetically modified crops (GMC, genetically modified crops, biotechnology crops) are plants used in agriculture, and their DNA has been recombined using genetic engineering techniques. In most cases, the aim is to introduce new traits into plants that are not naturally found in species. Examples of edible crops include resistance to certain pests, diseases or environmental conditions, reduced spoilage or resistance to chemical treatment (eg tolerance to herbicides), or improved nutritional characteristics of the crop. Examples of non-edible crops are production chemicals, biofuels, other indust
