Introduction Genetic modification is a biological technique that effects alterations in the genetic machinery of all kinds of living organisms. GMO is defined as follows by WHO (World Health Organization): “Organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been J. Mater. Environ.

The aim of the review study to find out the positive and negative effect of GM crops on human health and environment finally awareness to the people to acceptance the GM crops it beneficial effect from lowest hazard. Opportunity presented by proponents of GM technology include development in fruit and vegetable shelf- life and organoleptic quality, prosperous nutritional quality and health benefits in foods, elevated protein and carbohydrate content of foods, exalted fat quality, high quality and quantity of meat, milk and livestock. We study various type of review article on GM foods and findings the positive effect it’s the methodology of this paper. In addition, some more common concerns include environmental pollution, unintentional gene alteration to wild plants, probable creation of new viruses and toxins, restricted access to seeds due to patenting of GM food plants, impedance to crop genetic diversity, religious, cultural and ethical concerns, as well as fear of the unknown. Boosters of GM technology include private industries, research scientists, some consumers, U.S. farmers and regulatory agencies. The result of the study minimizing potential risks and maximizing the profits of GM foods finally it should be approval for us. Because the advantage of GM foods ostensibly far out weights the risks, regulatory agencies and industries engaged in GM food business. Finally increment public awareness in this technology to prolong worldwide acceptability of GM foods will be reducing in future of food crisis in the world.
