　　Dispute About Genetically Engineered Rice

　　关于转基因大米的争议

　　Scientists in the Philippines are working to make changes to rice. They hope these changes will help solve one of the world’s biggest health issues: the lack of Vitamin A.

　　It is called “golden rice” because the rice is yellow. It has been genetically changed, or modified, to produce beta carotene, a form of Vitamin A.

　　Opponents of genetically modified foods – including the environmental group Greenpeace – do not like what the scientists are doing. But supporters of golden rice say it could help save as many as two million lives a year. Young children and pregnant women can, and do, die from Vitamin A deficiency.

　　Vitamin A is missing from the food of millions of people in the developing world. The deficiency is the leading cause of childhood blindness. It is a public health problem in half of all countries, including many in Africa and Southeast Asia.

　　Patrick Moore is an ecologist and former Greenpeace president. He supports production of golden rice. He says there should not even be debate about the issue while children starve.

　　Mr. Moore left Greenpeace in the 1980s and disagrees with many of its positions.

　　VOA asked Greenpeace to answer Mr. Moore’s criticisms of its opposition to golden rice. The group answered in an email. It read: “Genetically engineered crops consistalmost entirely of herbicide-tolerantand insect-resistantcrops marketed to developing countries.”

　　It said this agricultural model damages human health and hurts farmers and the environment.

　　Large companies do produce some genetically modified crops. They gain legal control of the plant production through patents. But in the Philippines, government and donor money is being used to develop golden rice in the Philippines. These groups hope farmers throughout the developing world will someday grow it. They hope it will help solve a problem that many scientists believe is as serious as malaria or tuberculosis.

　　Daniel Ocampo is a Southeast Asia agriculture expert for Greenpeace in Manila. He argues that golden rice is still not ready as a food for humans after 20 years of research. He says it could be more dangerous than its supporters will admit.

　　The International Rice Research Institute in the Philippines has been experimenting with golden rice for nine years. It says it has more work to do before the rice can be eaten by humans.

　　时间状语从句: while children starve
