4、neer for all peopleAlthough he is one of Chinas most famous scientists, Yuan Longping considers himself a farmer, for he works the land to do his research. Indeed, his sunburnt face and arms and his slim, strong body are just like those of millions of Chinese farmers, for whom he has struggled for t
5、he past fice decades. Dr Yuan Longping grows what is called super hybrid rice. In 1974, he became the first agricultural pioneer in the world to grow Rick that has a high output. This special strain of Rick makes it possible to produce one-third more of the crop in the same fields. Now more than 60%
6、 of the rice produced in China each year is from this hybrid strain.Born into a poor farmers family in 1930, Dr Yuan graduated from Southwest Agricultural College in 1953. Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for incresing the rice
7、output. At that time, hunger was a disturbing problem in many parts of the countryside. Dr Yuan searched for a way to increase rice harvests without expanding the area of the fields. In 1950, Chinese farmers could produce only fifty million tons of rice. In a recent harvest, however, nearly two hund
8、red million tons of rice was produced. These increased harvests mean that 22% of thwart worlds people are fed from just 7% of the farmland in China. Dr Yuan is now circulating his knowledge in India, Vietnam and many other less developed countries to increase their rice harvests. Thanks to his resea
9、rch, farmers are producing harvests twice as large as before.Dr Yuan is quite satisfied with his life. However, he doesnt care about being famous. He feels it gives him less freedom to do his research. He would rather keep time for his hobbies. He enjoys listening to volin music, playing mah-jong, s
10、wimming and reading. Spending money on himself or leading a comfortable life also means very little to him. Indeed, he believes that a person with to much money has more rather than fewer troubls. He therefore gives millions of Yuan to equip others for their research in agriculture.Just dreaming for
11、 things, however, costs nothing. Long ago Dr Yuan had a dream about rice plants as tall as sorghum. Each ear of rice was as big as an ear of corn and each grain of rice was as huge as a peanut. Dr Yuan awoke from his dream with the hope of producing a kind of rice that could feed more people. Now, m
12、any years later, Dr Yuan has another dream: to export his rice so that it can be grown around the glboe. One dream is not always enough, especially for a person who loves and cares for his people.Chemical or organic farming?Over the past half century, using chemical fertilizers has vecome very commo
13、n in farming. Many farmers welcomed them as great way to stop crop disease and increase production. Recently, however, scientists have been finding that long-term use of these fertilizers can cause damage to the land and, even more dangerous, to peoples health.What are some of the problems caused by
14、 chemical fertilizers? First, they damage the land by killing the helpful bacteria and pests as well as the harmful ones. Chemicals also stay in the ground and underground water for a lonog time. This affects crops and, therefore, animals and humans, since chemicals get inside the crops and cannot j
15、ust be washed off. These chemicals in the food supply build up in peoples bodies over time. Many of these chemicals can lead to cancer or other illnesses. In addition, fruit, vegetables and other food grown with chemical fertilizers usually grow too fast to be full of much nutrition. They may look b
16、eautiful, but inside there is usually more water than vitamins and minerals.With these discoveries, some farmers and many customers are beginning to turn to organic farming. Organic farming is simply farming without using any chemicals. They focus on keeping their soil rich and free of disease. A he
17、althy soil reduces disease and helps crops grow strong and healthy. Organic farmers, therefore, often prefer using natural waste from animals as fertilizer. They feel that this makes the soil in their fields richer in minerals and so more fertile. This also keeps the air, soil, water and crops free
18、from chemicals.Organic farmers also use many other methods to keep the soil fertile. They often change the knd of crop in each field every few years, for example, growing corn or wheat and then the next year peas or soybeans. Crops such as peas or soybeans put important minerals back into the soil,
19、making it ready for crops such as wheat or corn that need rich and fertile soil. Organic farmers also plant crops to use different levels of soil, for example, planting peanuts that use the grounds surface followed by vegetables that put down deep roots. Some organic farmers prefer planting grass be
