Did your opinion about GMOs change after carefully evaluating their benefits and risks? Why or why not? Which argument is the most compelling, and why?
EXPLAIN GMOs have offered opportunities in a wide range of sectors such as in agriculture, health and medicine, research, industry and bioremediation. A. Agriculture DIFFERENT APPLICATIONS of GMOs There are numerous genetically engineered products in agriculture. Among these is Bovine somatotropin (bST) (1993) which is a metabolic protein hormone used to increase milk production in dairy cows for commercial use. Bt crops (corn and potatoes) produce toxin to kill pests were approved safe by the Environmental Protection Agency. Flavr Savr tomato (1994) has delayed ripening effect that gives a longer shelf life compared with natural tomatoes and increase lycopene. Another is weeds resistant to glyphosate (1996). These super weeds are 7 to 11 times resistant to glyphosate than the standard susceptible population. Rainbow papaya (1998) is Hawaiian papaya resistant to Ringspot virus because it can produce the Bt toxin. Golden rice (Oryza sativa) (2000) was developed in the Philippines to address the issue of vit. A deficiency. The golden rice is modified to biosynthesize beta carotene, a precursor of vit. A. Yorkshire pigs (2006) are genetically modified to produce offspring that produce the enzyme phytase in their saliva to digest plant phosphorus. B. Medicine -Humulin (1982), a type of insulin produced using genetically engineered E. coli bacteria is available in the market. It is the first GMO approved by FDA. -The drug, ATryn, an anticoagulant used to reduce blood clots during surgery or childbirth is extracted from the goat's milk. -Another promising innovation is Banana vaccines. People may soon be getting vaccinated for diseases like hepatitis B and cholera by simply taking a bite of banana. Researchers have successfully engineered bananas, potatoes, lettuce, carrots and tobacco to the ideal production and delivery vehicle. When an altered form of a virus is injected into a banana sapling, the virus' Page | 4
