Norman Borlaug was born in 1914 on a farm in the American state of Iowa. In the middle of the 20th century, world population was expanding faster than food production. Experts said many people in developing countries would face starvation.

　　Norman Borlaug was an agricultural researcher at the International Maize and Wheat Improvement Centre in Mexico. He developed methods of growing wheat that increased the amount harvested by three times. He later repeated this success in India, Pakistan and Africa.

　　His methods of farming saved millions of people who would have starved to death. Norman Borlaug was given the Nobel Peace Prize for his efforts in 1970.

　　Norman Borlaug is still urging experts to think about the needs of people around the world. His latest concern is a disease in wheat called UG 99.He says it has the power to destroy most of the wheat being grown around the world. He says reductions in agricultural programmes have made it harder to take action against such threats.

　　Mr Borlaug's granddaughter Julie works at the centre named after him at Texas A&M University in Dallas. She says his worry about food problems rises from the belief that hunger is unacceptable. She says Norman Borlaug still believes it is our responsibility as human beings to feed one another.

　　11. Norman Borlaug was ________ years old when he was given the Nobel Prize.
