Social Controversy“If some people decide that they want blind

children and white rice, it’s their decision. I’m offering the possibility of yellow rice and no blind children. But the decision what people want to eat is theirs." Dr. Potrykus

“Malnutrition is not merely a nutrition problem, it is also a social problem.” Dr. Samson Tsou

Greenpeace claimed Golden Rice is “not effective” and “superfluous”

Political Controversy

• Delayed processes• Permits• Lack of support

• Regulatory requirements• Large corporations• Public sector

– Loss of investments and opportunities– Increase cost

Coming Soon!

• Golden Rice should be on Sale in the Philippines by 2012
