White rice is the world's most popular form of rice.But it goes through a million process that removes many nutreons.As  result,people who eat a poor diet based on the white rice may not get enough vitamine A.Each year an estimated 250,000 to half a million children go blind from vitamine A defficiency.The World Health Organization says half of them die within a year of losing their sight.Vitamine A defficiency is a problem especially in Africa and southeast Asia.So scientists vote for an answer.They combined white rice with plat compounds that the body can change into vitamine A.The rice contains bata carrotine and other (corroter noints).This plat colorings give the rice a golden color.The scientists also folled of a plan to give a way this golden rice for free to poor farmers.But the rice is genetically engineered. They say it cannot be made using traditional methods to (pree) plants.The scientists worked for 10 years until 1990 to develop the technology to add genes to rice.Then it took 9 more years to get the genes they wanted into the seeds.The first few tests took place in 2004 at Luisiana State University in the US.Golden rice is currently been tested in the Phillipines.It is still not available in (general) use.(Coenventer Ingopatric) says rice with 2 added genes will be available in 2013. One gene comes from mais or corn and the other from a soil bacterium.Mr.( Patric) is retired from the Swiss Federal Institute of Technology.He blames the delays on too many rules of tranadically modify crops. Opponants say such crop may cause environmental damage by weeding with conventional plants.Opponants also question the safety of biotech foods.Mr.Patrioc says golden rice has never been shown to be unsafe for the environment or people.Many agricultural organizations support the project. But there are also critics including researches for the environmental group, Green Peace.Several months ago they questioned whether goleden rice could do much for vitamine A defficiency.They said releasing genetically mode of white rice in nature could prominately change traditional rice varieties and wild ancestors of rice.
