"Genetically Engineered Crops: Their Potential Use for Improvement of Human Nutrition" was written by Dr. Lin Yan and Dr. Philip S. Kerr. The focus of the article was to discuss research being done to help feed the increasing world population with new scientific discoveries that have been made since World War Two. The most monumental discoveries have been the discovery of "chemical processes to reduce nitrogen and ammonia" as well as fertilizers with nitrogen in them and chemical pesticides to control insects. Irrigation techniques and improved use of seeds have helped meet the world's increased demand for food sources (Yan and Kerr, 2002, p.135). Dr. Yan and Dr. Kerr call the increasing world population and greater need for food to feed this population the "green revolution". Estimates indicate that although the current agricultural system is meeting the dietary needs of the population growth, it could one day be insufficient. The protein requirement future populations may require will put too much pressure on already limited resources, which is where today's research comes into play. Today's research is called Biotechnology, Dr. Yan and Dr. Kerr focus on how scientists study alternatives to increase agricultural productivity and eliminate environmental risks. According to the article, one of the most common problems with the current nutrition of the world is "Anemia", also called Iron Deficiency. By further investigating biotechnology, scientists could find some way to alter foods to increase iron levels to a more healthy range for today's society. One of the biggest successes in plant biotechnology is the number of plants capable of manufacturing an insecticide protein encoded by a gene isolated from the bacterium Bacillus thuringiensis (Bt). Having this protei ...
