Genetic engineering holds the key to feeding the world¡¦s growing population, curing our diseases and saving our natural resources. Welcome to the brave new world of farming, ¡§Transgenic Crops¡¨. Genetically modified crops or food is a very controversial subject these days, with statements ranging from, the cure to world hunger, to the creators of the super-weeds and pesticide resistant insects, to so called ¡§Frankenfoods¡¨, it is no wonder that the average consumer is confused, or unaware of genetically modified crops, or ¡§GM crops¡¨. Millions of acres have made the switch to transgenic crops just over the last two years, (see appendix A). With the numerous farmers making the switch, the biggest thing remaining is educating the public. It is estimated that as much as 60-70% of packaged foods already contain ingredients from genetically modified crops or organisms. That means it is in grocery items ranging from canned soup to breakfast cereal. And no one has been reported to die from eating it. . Just about every grain, legume, vegetable and fruit have already been genetically altered in the laboratories, along with many organisms that are used either directly as food, or in production. Just a few examples of genetically modified crops are: Maize, potatoes, soybean, yeasts, herbicide and pesticide resistant crops and modified food additives and enzymes. Even though the effects of genetically modified food will have both positive and negative impacts on the human population, they will impact every person differently. For several thousand years, farmers have been altering the genetic makeup of the crops they have been growing by crossbreeding. They have made plants grow faster, hardier, produce larger seeds, or give them some other desired quality. In the last 20 years, with new technology, researchers have been given the ability to remove specific genes from one species and add them to another, making this process far more precise and selective than with traditional breeding. According to Gary Barton, a researcher at Monsanto, they have been field-testing GM crops for some 13 years now. Last year alone (2000), there were over 100 million acres of transgenic crops grown all over the world and in many continents. The benefits of this new technology are endless. At the beginning of the century, the global population was approximately 1.6 billion. The United Nations estimates that the global population will reach 70 billion by 2030. Today, approximately 70% of the people on the planet grow what they eat. Researchers are estimating that produce output will have to double on existing land over the next 30 years if we are to be able to keep up with the expected population growth. In the next 20 years, the U.N. estimates that half the population will live in cities and need to be fed through different market systems. GM crops could be bioengineered to tolerate poor climatic and soil conditions, including acidic solids, drought, flood plains, and high salinity levels, conditions, which prevail in many developing countries. For instance, 43 percent of tropical soils are acidic, and 1/3 of the world¡¦s irrigated land has been lost to salinity. This would then increase the number of areas able to grow their own crops, which currently cannot feed their populations. In 1995, hunger and malnutrition were responsible for 6 million, or 54 percent, of the deaths in children younger than 5 years, stunting in 200 million children and clinical xerophthalmia¡Xa condition of the eye, caused primarily by a lack of Vitamin A. We can increase the nutritional value of some food making them tastier, more appealing and possible lowering the amount of food a person needs to intake. GM food scientists have already developed a yellow rice, or ¡§golden¡¨ rice that is rich in vitamin A and iron and helps prevent anemia and blindness, especially in children. The bioengineers inserted genes from a soil bacterium and two genes...
