This is the VOA Special English agricultural report.Wide rice is the world's most popular form of rice.But it goes through a milling process that removes many nutrients.As a result people who eat a poor diet based on wide rice may not get enough Vitamine A.Each year an estimated 250,000 to half a million children go blind from Vitmine A deficiency.The World Health Organization says half of them die within a year of losing their sight. Vitmine A deficiency is a problem especially in Africa and Southeast Asia.So scientists thought of an answer.They combined wide rice with planed corn pones that the body can change in to Vitmine A.The rice contains beta-carotene and other carotenoids.This planed colorings give the rice a golden color.The scientists also thought of a plan to give away this golden rice for free to poor farmers.But the rice is genetically engineered. They say it cant not be made using traditional methords to preplans.The scientists work for ten years until 1990 to develop the technology to add genes to rice.Then it took nine more years to get the genes they wanted into the seed.The first fild tests took place in 2004 at Louisiana State University in the United States.Golden rice is currently being tested in the Phillipines.It is still not available for (general) use.Co-inventor Engo Partrick says rice with two added genes will be available in 2013.One gene comes from maize or corn and the other from a soil bacteria.Mr Partrick has retired from the Switz Ferderal Institut of Technology.He blames the delays on two many rules about genetically modified crops.Opponents say such crops may cause enviromental damage by breeding with conventional plants.Opponents aslo question the safety of biotech food.Mr Partrick says golden rice has never been shown to be unsafe to the environment or people.Many agricultural organizations support the project.But there are also critics including researchers for the Environmental Group Green Peace.Several monthes ago they questioned whether golden rice could do much for Vitmine A deficiency.They said releasing genetically modified rice in Asia could permanently change traditional rice varieties and wild ancesters of rice.And that's the VOA Special English Report written by...
