There are many factors that influence food supply. These can be political, economic, social, as well as environmental or agricultural. Since there are no “quick-fix” technical solutions to social and political problems, new agricultural technologies such as genetically modified crops are one of many important ways of helping protect and ensure the food supply. Agricultural biotechnology can be used to increase yields to provide more food by protecting against pests and other environmental challenges such as drought.
In the developing world, where food security is a much more pressing concern, genetically enhanced crops have been seen as a way to increase yields from the existing arable land. GM crops can help subsistence farmers provide more and better foods for their families or, in the case of revenue crops such as cotton, get more value from their land by increasing yield. Also, crops could be enhanced through biotechnology to contain more nutrients and help minimize the effects of malnutrition. Most importantly, GM crops can help provide these benefits in a sustainable way, so that increasing populations can be fed without placing additional pressure on natural habitats by destroying them through farming uses.
