Genetically modified or genetically engineered crops are one of most important and attracting field now these days. Such crops are produced by adding a transgene or an unrelated gene into the crop for a particular feature like insect, pest resistance, herbicide tolerance and also to increase yield for molecular farming for making edible vaccines etc. In relation to socio-economic impacts, GM crops have increased income for large- and small-scale commercial and subsistent farmers with associated downstream impacts through investments. Increased gross margins are due to higher revenues and reduced costs in relation to pest management. Issues such as debt problems caused by seed purchase occur but are no more extensive than for conventional crops; the question of crop monopolies by multinational companies remains though it must be acknowledged that such companies have invested cash billions in development and that they have little to gain by pricing farmers out of the market. Health benefits have also been achieved, especially through a reduction in pesticide use. Additional potential benefits of GM crops are discussed including possibilities for the improvement of human health by augmenting specific nutrients i. ebio fortification. But as every new technology has some positive and some negative affects it also have some. Like gene escape, environmental impact etc. but GM crops can help a lot to fulfil the demand of today’s increasing population. Likewise crop plants produce large amounts of biomass at low cost and require limited facilities. Since plants have long been used as a source of medicinal compounds, molecular farming represents a novel source of molecular medicines, such as plasma proteins, enzymes, growth factors, vaccines and recombinant antibodies, whose medical applications are understood at a molecular level. Biopharming promises more plentiful and cheaper supplies of pharmaceutical drugs, including vaccines for infectious diseases and therapeutic proteins for treatment of such things as cancer and heart disease.
