That is the question.

No, this is not a street racing sitehere you will find arguments for and against the proliferation of Golden Rice, pun intended.

For

The main purpose of Golden Rice is to increase the amount of Vitamin A in the diet of the impoverished in developing countries. Lack of Vitamin A has been proven to the the leading cause of blindness in children in developing countries (WHO, 2011). Research by the Paine et al, (2005) shows that in some strains of Golden Rice, up to 36.7 µg of carotenoids are present in every gram of Golden Rice, with ~85% of it in the form of beta-carotine. This implies that the RDI of Vitamin A in 4-8 year old children could be reached with about 133 grams of Golden Rice, this amount may be reduced if the child's diet is more diverse. Still the rice, if mass marketed, could very well reduce the incidence of fatalities and blindness from Vitamin A deficiency,

The development of Golden Rice is a part of the greater green revolution, where genetic modification has and is been used to increase yields through the addition of insecticidal and herbicidal properties, as well as being more nutritious as is the case for Golden Rice. The experience gained in these developments will be useful in further genetic engineering which will have far ranging effects. 

In communities without a supply of leafy greens or other supply of Vitamin A, more relevant since the advent of the Global Food Crisis, Golden Rice would be very helpful in reducing the occurance of Vitamin A deficiency. (Weale, 2008)

Against

The amount of Golden Rice stated to the left is only for a very recent strain that has not undergone much testing at all. Furthermore it does not account for loss in beta-carotene during cooking. Greenpeace (2001) estimates cooking losses at up to 50%. Also human trials conducted during 2009 about the health effects of Golden Rice have yet to have their results published, raising further doubt. (GMwatch, 2010)

The Golden Rice project in all cost over $100 million dollars in funding from charitable donations according to The Institute of Science in Society, yet after 20 years or development, Golden Rice still has not been commercialized despite major deals with the pharmacological company AstraZeneca to provide the rice free of charge to poor farmers. However, Greenpeace (2005) suggests that this is simply a way to make inroads for GM crops, which in their opinion are highly dangerous due to the issue of genetic pollution, where GM crops spread and are mixed into the gene pool of unaltered plants. The consequence of this is yet unclear, the odds are particularly great due to rice being a staple food for much of the world.

Vitamin A is obviously not the only macro-nutrient that the people of developing countries lack, furthermore, beta-carotene unable to be converted to useful retinol without the body possessing adequate reserves of Vitamin E, zinc, protein and fat (Greenpeace, 2010). The introduction of of this rice may reduce the perceived need for a varied diet.
