Study of heredity and variation in living organisms.
Genetically modified (GM) foods are made from plants or animals whose DNA has been changed to give them new traits.
Most scientific studies show that GM foods currently on the market are safe to eat. However, people debate their impact on the environment and food supply.
GM foods help farmers grow more food and can make healthy food more available around the world.
Some countries require labels on GM foods so people can choose what they eat.
Golden rice is engineered to have more vitamin A, helping reduce blindness in children.
Bt corn produces a natural insecticide, so farmers use fewer chemicals.
