3: What are some of the effects on the environment from increasing pesticide use? What is the impact on pest control from our increasing use in crops of insecticide-encoding genes from the soil bacterium // [|Bacillus thuringiensis?] // The long-term environmental implications largely gravitate toward a high risk of rapid insect adaptation and loss of crop. Resulting from increased insecticide use, and adaptation, pests develop a resistance to their repulsion and eat the crops regardless of modification, offering a loss of product

4: What is genetic engineering and why is it controversial ? Scan a few of the articles and summarize your findings. Genetic engineering isdirect human manipulation of an organism's genome using modern DNA technology. Because it is a big scary term and people are messing with the food others eat, concern is as natural as the issues that are generated. Critics have feared that genetically engineered products have been rushed to market before effects are fully understood. In the case of taco shells contaminated with genetically engineered corn not approved for human consumption, the fear is valid. The potential spread of noxious "superweeds" spawned by genes picked up from engineered crops, though, and possible harmful effects of biotech corn pollen on monarch butterflies, are also panic inducing facts that cannot be ignored. Despite the obvious financial benefits of an unnatural harvest, it is quite clearly not the greatest half-assed idea on market.
