o More efficient processing

o Pharmaceuticals Medicines and vaccines often are costly to produce and sometimes require special storage conditions not readily available in third world countries. Researchers are working to develop edible vaccines in tomatoes and potatoes16, 17. These vaccines will be much easier to ship, store and administer than traditional injectable vaccines.

o Pest resistance Crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries. Farmers typically use many tons of chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards, and run-off of agricultural wastes from excessive use of pesticides and fertilizers can poison the water supply and cause harm to the environment. Growing GM foods such as B.t. corn can help eliminate the application of chemical pesticides and reduce the cost of bringing a crop to market
Controversies- disadvantage
? Violation of natural organisms' intrinsic values
? Tampering with nature by mixing genes among species
? Objections to consuming animal genes in plants and vice versa
? Stress for animal
? Unknown effects on human health There is a growing concern that introducing foreign genes into food plants may have an unexpected and negative impact on human health

1.Genetically modified (GM) foods are foods made from genetically modified organisms (GMO) that have had their DNA altered through genetic engineering. GM foods were first put on the market in the early 1990sThe most common modified foods are derived from plants: soybean, corn, canola, and cotton seed oil.
Future developments
Future envisaged applications of GMOs are diverse and include drugs in food, bananas that produce human vaccines against infectious diseases such as Hepatitis B, metabolically engineered fish that mature more quickly, fruit and nut trees that yield years earlier, and plants that produce new plastics with unique properties. While their practicality or efficacy in commercial production has yet to be fully tested, the next decade may see exponential increases in GM product development as researchers gain increasing access to genomic resources that are applicable to organisms beyond the scope of individual projects. Safety testing of these products will also at the same time be necessary to ensure that the perceived benefits will indeed outweigh the perceived and hidden costs of development. Plant scientists, backed by results of modern comprehensive profiling of crop composition, point out that crops modified using GM techniques are less likely to have unintended changes than are conventionally bred crops.[31][32]

With Article
Genetically modified (GM) crops and food are being grown and consumed by the public, even though:
? there is little scientific study about their health risks
? safety test technology is inadequate to assess potential harm
? they can carry unpredictable toxins
? they may increase the risk of allergenic reactions
