1Genetically engineered foods are foods that are produced from genetically modified crops. Genetically modified crops are those that have had their genetic make up altered by a process called recombinant DNA technology. This involves inserting specific selected genes into the plant to be modified, to either give it certain desirable traits or to eliminate certain undesirable traits.
2 .Genetic engineering of food crops might threaten biodiversity. Many native crops, vegetables and fruit could disappear as more land is used for GM crops.
    As GM seeds are patented, many critics of genetically engineered crops are concerned that a handful of GM companies would have control over a large percentage of the world's food production.
    There have been no extensive field studies regarding the long term impact of GM crops on the environment. Some consumer organisations and lobby groups claim that not enough is known about the long term health effects of eating food made with genetically engineered crops.
3.yes.the benefits outweight the risk.Because with the genetically engineered foods make food have less disease.
