Genetically modified foods ( GM foods or GMO foods) are foods resulting from GMOs. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. Sarthak Sharma (7BB) What’s GM food?
The world population is more than 6 billion people and is predicted to double in the next 50 years. GM food helps enhancing quality and quantity of food. Making sure we have an enough food supply for this booming population is going to be a big challenge in the years to come. Sarthak Sharma (7BB) What is the need of GM food?
Disease resistance There are many viruses, fungus and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically-engineered resistance to these diseases. Nutrition Malnutrition is common in under developed countries where peoples rely on a single crop such as rice for the main food of their diet. However, rice does not contain enough amounts of all necessary nutrients to prevent malnutrition. If rice could be genetically engineered to contain additional vitamins and minerals, nutrient deficiencies could be eliminated. Sarthak Sharma (7BB) Other advantages of GM food
Criticism to GM foods EEnvironmental activists, religious organizations, public interest groups, professional associations and other scientists and government officials have all raised concerns about GM foods, and criticized business for pursuing profit without concern for potential hazards, and the government for failing to exercise enough deplane oversight. It seems that everyone has a strong opinion about GM foods. Even the Most concerns about GM foods fall into three categories: environmental hazards, human health risks, and economic concerns.

* Reduced effectiveness of pesticides Just as some populations of mosquitoes developed resistance to the now-banned pesticide DDT, many people are concerned that insects will become resistant to B.T. or other crops that have been genetically-modified to produce their own pesticides. * 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.
PUBLIC OPINION ON GM FOOD SARTHAK SHARMA (7BB) Genetically-modified foods have the potential to solve many of the world's hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing dependence upon chemical pesticides. Yet there are many challenges ahead for governments, especially in the areas of safety testing, regulation, international policy and food labeling. Many people feel that genetic engineering is the unstoppable wave of the future and that we cannot afford to ignore a technology that has such enormous potential benefits. However, we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.
GM food is good but I think it’s way too risky.The food might mutate too much and will may cause world wide threat.
