Effects Of Genetic Engineering On Agriculture
Effects Of Genetic Engineering On Agriculture
The Effects of Genetic Engineering on Agriculture Agribiotechnology is the study of making altered agricultural products. Agribusiness is trying to alter the genes of already existing products to try to enhance the biocompetitiveness and adaptability of crops by enhancing plant resistance to drought, salinity, disease, pests and herbicides. They are going to try to enhance their growth, productivity, nutrient value, and chemical composition. The old way of doing this was through selective breeding, special fertilizer, and hormones. This seems now somewhat outdated with todays technology. Genetic engineering comes with many downfalls. Increased production through genetic engineering could exhaust nonrenewable resources more rapidly and fail to feed a larger and more dependent human population. In Africa, and South and Central America, super breeds of crops, irrigation and hydroelectric dams, chemical fertilizers, pesticides, and agripoisons exported to less developed countries produced great short-term profits but destroyed already existing, more regenerative, traditional farming practices, ultimately destroying the communities and fragile land. Natural deserts, swamps and salt marshes need to be preserved to protect biodiversity and the integrity of the Earths ecology. Introducing genetically engineered organisms into the environment means that these areas could be invaded by these new
