Why do monocultures require large inputs of weed killers and pesticides? 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?]// What is genetic engineering and why is it controversial? Scan a few of the articles and summarize your findings.

__**#1. Why do monocultures require large inputs of weed killers and pesticides?** __ Monocultures require large inputs of weed killers and pesticides, because it is too costly for farmers to organically grow large crops. __**#2. What are some of the effects of the environment from increasing pesticide use? What is the impact control from out increasing use in crops of insecticide-encoding genes from the soil bacterium Bacillu thuringiensis? **__  Side effects of increasing pesticide use are, soil degradation, loss of top soil, and much weaker plants. __**#3. What is genetic engineering, and why is it controversial? **__ Genetic engineering is when you change the put foreign attributes (DNA) into something to make it better. It's controversial because it can be a downgrade at times too, and diseases can become stronger and dominate that species.
