Uni t 2 A pi oneer for al peopl e Al though he i s one of Chi na?s m ost fam ous sci enti sts, Yuan Longpi ng considers him sel f a farm er, for he works the land to do hi s research. Inded, hi s sunburnt face and arms and his sl im, strong body are just li ke those of mi l i ons of Chi nese farm ers, for whom he has struggl ed for the past fi ce decades. Dr Yuan Longpi ng grows what i s cal ed super hybri d ri ce. In 1974, he becam e the fi rst agri cul tural pi oneer i n the worl d to grow Ri ck that has a hi gh output. This speci al strai n of Ri ck m akes i t possi bl e to produce onethi rd m ore of the crop i n the sam e fi el ds. N ow more than 60% of the ri ce produced i n Chi na each year i s from thi s hybri d strai n. Born i nto a poor farm er?s fam il y i n 1930, Dr Yuan graduated from Southwest Agri cultural Col l ege i n 1953. Si nce then, fi ndi ng ways to grow m ore rice has been his l i fe goal . As a young m an, he saw the great need for i ncresing the ri ce output. At that tim e, hunger was a di sturbi ng probl em i n m any parts of the countrysi de. Dr Yuan searched for a way to i ncrease ri ce harvests without expandi ng the area of the fi el ds. In 1950, Chi nese farmers coul d produce onl y fifty mi l i on tons of ri ce. In a recent harvest, however, nearl y two hundred m il li on tons of rice was produced. These i ncreased harvests m ean that 22% of thwart worl d?s peopl e are fed from just 7% of the farm l and i n Chi na. Dr Yuan i s now ci rcul ati ng his knowl edge i n Indi a, Vi etnam and m any other l es devel oped countri es to i ncrease thei r rice harvests. Thanks to hi s research, farm ers are produci ng harvests twi ce as l arge as before. Dr Yuan is qui te sati sfi ed wi th hi s li fe. H owever, he doesn39。t care about bei ng famous. H e fel s it gi ves him l es fredom to do hi s research. H e woul d rather keep tim e for his hobbi es. H e enjoys li steni ng to vol i n m usic, pl ayi ng m ahjong, swimm i ng and readi ng. Spendi ng m oney on hi msel f or l eadi ng a fortabl e li fe al so means very li ttl e to hi m. Indeed, he beli eves that a person with to m uch m oney has m ore rather than fewer troubls. H e therefore gives mi l i ons of Yuan to equi p others for their research i n agri cul ture. Just dream i ng for thi ngs, however, costs nothi ng. Long ago Dr Yuan had a dream about ri ce pl ants as tal as shum. Each ear of ri ce was as bi g as an ear of corn and each grai n of ri ce was as huge as a peanut. Dr Yuan awoke from hi s dream wi th the hope of produci ng a ki nd of ri ce that coul d feed m ore peopl e. N ow, m any years later, Dr Yuan has another dream: to export hi s ri ce so that it can be grown around the gl boe. One dream is not al ways enough, especi al l y for a person who l oves and cares for his peopl e. Chem i cal or ani c farmi ng? O ver the past hal f century, usi ng chem ical ferti li zers has ve e very m on i n farm i ng. Many farm ers wel ed them as great way to stop crop di sease and i ncrease producti on. Recentl y, however, sci enti sts have been fi ndi ng that longterm use of these ferti li zers can cause dam age to the l and and, even m ore dangerous, to peopl e?s heal th. What are som e of the probl em s caused by chemi cal fertil i zers? Fi rst, they damage the l and by ki l ing the hel pful bacteria and pests as wel l as the harm ful ones.
