Golden rice is a GM variety of rice. It has been given genes that make it produce a substance that the human body converts into vitamin A. A lack of vitamin A in the diet causes blindness in about 250 000 children each year. Most of these children live in countries where rice is the main food.
Evaluate the use of golden rice to reduce blindness in children.
