_1. Yuan Longping was born in 1930. Since he graduated from Southwest Agricultural College in 1953, he has devoted his life to finding ways to grow more and more rice. As a young man, he saw the great need for increasing the rice output. At that time, hunger was a serious problem in many parts of the countryside. He searched for a way to increase rice harvests without expanding the area of the fields. In 1950, Chinese farmers could produce about fifty-six million tons of rice. In a recent harvest, however, nearly two hundred million tons of rice was produced. These increased harvests mean that 22% of the worlds people are fed from just 7% of the farmland in the world. Yuan is now circulating his knowledge in many less developed countries. Thanks to his research, the UN has more tools to rid the world of hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.2. Since Yuan Longping graduated from college, he has devoted his life to finding ways to grow more rice.
