    Genetically modified (GM) foods are food items that have had their DNA changed through genetic engineering. Unlike conventional genetic modification that is carried out through conventional breeding and that have been consumed for thousands of years, GM foods were first put on the market in the early 1990s. The most common modified foods are derived from plants: soybean, corn, canola, and cotton seed oil. For example, a typical GM Food could be a strawberry that has to survive in cold climates. Therefore, the farmer would get its DNA altered so it could survive in the frost. They would take DNA from a frost resistant cell, and transfer it into the strawberry cells genes. Therefore, the cells of the strawberry are now frost resistant and will survive the frost, so the farmer does not lose money. [1][2]

    Many major controversies surround genetically engineered crops and foods. These commonly focus on the long-term health effects for anyone eating them, environmental safety, labeling and consumer choice, intellectual property rights, ethics, food security, poverty reduction, environmental conservation, and potential disruption or even possible destruction of the food chain. The multi-national corporations and governments engaged in the genetic engineering of food claim the technology to be a boon for the human race, while many health-conscious people believe it to be a potential and/or actual disaster.
