The genetically modified foods were introduced to the world due to many advantages it has over the conventional foods. As we all know, there is only a limited earth surface suitable for cultivating. Due to the increasing earth population, it is obvious that one day, the food supply will not simply enough to cater the demand. In order to prevent such situation, the scientists have come up with genetically modified foods where they can use for producing more crops using the same amounts of resources. There are a number of benefits of genetically modified foods and let?s have a look at those.Farmers who grow genetically engineered food are greatly benefitted by their added qualities. Some genetically engineered food crops are modified to be able to withstand certain herbicides so that the farmers are able to use them liberally to get rid of weeds while others are created with built in pesticides that repel bugs and other pests. Other genetically engineered food is created with l ong life and resilience to adverse weather conditions in mind. For instance, some species of corns are created to withstand the harsh chill of winter and to keep them from rotting in heavy rains. Other species such as tomatoes which are one of the first vegetables to be engineered are modified to have a more vibrant colour, better taste and much longer shelf life not to mention .Tomatoes are the other food stuff believed to yield far superior benefits of organic food than its conventional cousin; this is according to a decade long study carried out by the University of California, Davis. Organic tomatoes are grown in an environment that has a lesser nutrient supply as nitrogen enriched chemical fertilizers are not included. Thus because of this fact there is a greater increase in the formation of antioxidants like quercetin which there is a 79 increase and kaempferol which is 97 higher in organic tomatoes. This is essentially good news as antioxidants are vital for over all good health as they have fight carcinogenic properties such as free radicals.

Though genetic engineering techniques such as gene splicing of different species or cloning are generally frowned upon by the public as unethical practices that are against the rules of nature, these very procedures can save certain animals from going extinct and from becoming endangered due to manmade effects. The main dangers associated with genetically modified animals and the techniques used to create them are the risks of misuse and the disruption of natural genetic information. Since most modified farm animals are released out to nature, a lot of people are worried that they may cause disruption to the eco system and the delicate balance of nature with their un-naturally enhanced characteristics. It is considered that with the large amount of genetically modified animals and plants in the world today could lead to the acceleration of genetic erosion, harmful and dangerous mutations as well as the creation of all new diseases that could pose a threat to mankind
