So you're saying because 1 Million children die every year is due to Vitamin A you believe the answer is genetically modify rice rather than actually feed the children a balanced diet of Vitamin A enriched foods (carrots, sweet potatoes, spinach, kale...?) or even supplements?

I suppose in theory we can put every nutrient needed known to man in a grain of rice one day.

But just because you could, does it mean you should? I suppose this opens up a much more broader discussion of morals, ethics and potentially alogical topics of conversation.
