Biologists have thought of a new to increase the of crops by 20 per cent. They genetically modified the in plants that is for photosynthesis. Photosynthesis is the chemical reaction where plants use sunlight to change carbon dioxide into . It lets us breathe. The scientists found a way for plants to use the energy they get from better, so they produce more food. Lead researcher Professor Stephen Long said his is genetically modifying the world's biggest , such as rice, , maize and soybean.

The scientists changed the thing that plants use to protect from damage from the Sun's strongest . Plants turn their energy into heat when they become too . However, plants do this even when block the Sun. The scientists put copies of the heat-loss into plants. These speed up the heat-loss so the plants can return to using energy to grow. This could help the world's food . Professor Long said if he could get 20 per cent more food from crops, it would reduce the future on food supply.
