popular in our life When comparing them, we can see several outstanding similarities and difference between them There are two similarities that both GMF and natural food share First one is that they can protect the
environment because they need fewer chemical fertilizers and pesticides which decrease the greenhouse effect Another similarity between natural food and GMF is that they have good taste and rich nutritious values GMF contain more flavors and increase the amount of nutrition Natural food not only have natural flavor but also full the “ life – force” of nature, which along with vital vitamins minerals and phyto – nutrients lead to a positive natural state of physical and mental health and vibrancy Although they bear some sameness, thi distinction between natural food and GMF are remarkable First
of all, they are different in shelf life The shelf life of GMF is more than that of natural food, implying that people can store it safely for a longer duration On the contrary, since natural food is minimally processed, many food items which have a high water content have a subsequently, shorter shelf life

artificial preservatives Though genetic engineering, on the contrary, the
genes are altered to be disease – resistant, pet – resistant, to product more, to enhance the natural qualities of food and lead to more efficient and profitable farming It is possible to maintain food’s freshness and extend food life
without relying on preservatives Another remarkable difference is the
uneven price between organic and GM foods Lower production rates and higher cost as overhead for labour make organic foods more expensive Owing
to GM methods, on the other hand, crop yields become incredible with lower costs, which means that food prices would go down and are cheaper than other foods When comparing, organic and GM foods might have the same nutritional value, they have several significant differences There is no doubt that, in the future, technology will continue to progress, researches may invest new good producting methods
