Genetically Modified Crops and the Third World Allison Miller “Worrying about starving future generations won’t feed the world. Food biotechnology will.” --Monsanto advertising campaign, 1998
Genetic Modification (rDNA Methods) • Can use genes from any living organism • Can modify one gene or several genes • Traditional Plant Breeding • Can only cross with closely related species • Many genes are modified at once Genetic Modification vs. Traditional Plant Breeding Source: Lemaux 2008
Food and Agricultural Organization of the United Nations (FAO) estimates that: • 842 million worldwide are underfed • 798 million live in developing nations • World population is expected to reach 9 billion by 2050 Need for GM crops and Biotechnology Source: Sairam and Prakash 2010
“The affluent nations can afford to adopt elitist positions and pay more for food produced by the so called natural methods; the 1 billion chronically poor and hungry people of this world cannot. New technology will be their salvation, freeing them from obsolete, low-yielding, and more costly production technology.” --Norman Borlaug Source: Borlaug 2000
“To feed a world of 9 billion people in 2050…Africa has to increase its food production by 300%, Latin America by 80%, and Asia by 70%. Even North America would have to increase food production by 30% to feed its own projected population of 348 million people. Without an increase in farm productivity, an additional 1.6 billion hectares of arable land will be needed by 2050” -- R.V. Sairam and C.S. Prakash Source: Sairam and Prakash 2010
