When animal experiments and clinical trials (safety experiments) were completed in the United States, and it was necessary to expand the experimental scope (curative effect experiments), a China researcher proposed to conduct experiments in his hometown (Hengyang mountain area in Hunan, China meets the standards of poor areas and is easy to compare). However, some processes necessary for human experiments, such as submitting for trial and informing, are fraudulent, which is a bad behavior involving academic misconduct in the scientific community. The experiment was stopped urgently and the parties concerned were dealt with.
Later, all kinds of reverse organizations made a big fuss, all kinds of conspiracy theories, demonization, and all kinds of dirty water poured on them. Therefore, the follow-up verification and commercial planting of golden rice have been put on hold indefinitely.
Last year, more than 100 Nobel Prize winners (up to now, more than 120) jointly issued an open letter calling for restarting the golden rice program to help the poor in Africa and Asia, but it has not been resolved.
People who can surf the Internet are basically not short of carotene and do not belong to the target population of golden rice. However, it is really regrettable that the behavior of reverse organizations makes the poor all over the world pay for their own private interests.
