此外，生物技术也无法克服在发展中国家分配粮食的难题。从整体上看，世界生产的粮食足够养活所有人，但大部分粮食却不是在需要的地方。尤其在运输基础设施落后的国家，地理条件对食物供给的限制正如遗传学为食物供给带来的希望一样大。
Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won"t even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to needs of poor countries. A London-based company, for example, has announced that it will share with developing countries technology needed to produce vitamin-enriched "golden rice".
生物技术也面临自身的“分配”问题。许多转基因作物方面的尖端研究都是富国的私营生物技术公司进行的。对发展中国家的穷苦农民来说，这些公司的产品通常显得过于昂贵，而且这些产品中的大部分甚至无法到达最需要的地区。强大的经济刺激促使生物技术公司把富裕国家的市场作为第一目标，以便能够尽快回收产品开发的高额成本。不过，有些公司已开始对贫穷国家的需要做出反应。例如，一家总部在伦敦的公司已经宣布，它愿意和发展中国家一起分享生产维生素增强型的“金水稻”所需的技术。
