All breeding leads to genetic changes, but in recent decades, advances in the field of genetic engineering have allowed control over the genetic changes introduced into an organism. The process of genetic engineering is the targeted manipulation of a plant’s or animal’s DNA to modify specific traits, involving the incorporation of new genes from one species into a completely unrelated species. Crop plants, farm animals, and soil bacteria are some of the prominent examples of organisms that have been subject to genetic engineering. The crops or organisms being developed by such a process are known as Genetically Modified Crops or Genetically Modified Organisms (GMOs). The initial objective for developing plants based on GM organisms was to improve crop protection. The GM crops currently on the market are mainly aimed at an increased level of crop protection through the introduction of resistance against plant diseases caused by insects or viruses or through increased tolerance towards herbicides.
But the discussion of my present topic is:
Are Genetically Modified Crops/Food safe for human consumption?
The answer is YES, although there are still ongoing for and against debates over this issue. However, the U.S. National Academy of Sciences, the European Commission, the American Medical Association and the scientific academies of Britain, France and Germany reviewed the evidence and concur that existing GM foods are as safe and nutritious as conventional varieties. These organizations believe that genetic engineering and GE crops should be considered important options in the efforts toward sustainable agricultural production. http://www.geneticliteracyproject.org/wp/wp-content/uploads/2013/10/Nicolia-20131.pdf .
Global food production is facing several challenges such as climate change, population growth, and competition for arable lands. For this reason, conserving land to produce more food is a necessity for any long term plan. Biotechnology firms claim that transgenic crops promise bigger yields to create more efficient use of land, better resistance to weeds, pest and other diseases, , less use of herbicides and other pesticides, have better texture, flavor and nutritional value, and have a longer shelf life for easier shipping. In short, GM foods can create an essential sustainable way to feed the world.
