Pest resistance, herbicide tolerance, disease resistance, drought and salinity tolerance, improved nutrition and yield, better shelf-life, faster yield etc are some of the advantages of GM foods.

 Disadvantages:

i) Environmental hazards such as unintended harm to other organisms, reduced effectiveness of pesticides, gene transfer to non-target species

ii) Human health risks such as allergies to such foods and unknown effects on human health from such foods.

iii) Economic concerns since developing such foods is a costly process and patenting them will lead to high prices for their seeds.
