Describe what is meant by the “green revolution” in agricultural systems. How has this revolution allowed modern human civilization to avert a Malthusian outcome over the twentieth and early twenty-first centuries? But why is agriculture also recognized as a primary driving force for global environmental problems like habitat destruction, cultural eutrophication, water scarcity, and soil contamination? Discuss at least two ways in which specific kinds of genetically modified organisms (GMOs) could credibly reduce the environmental impacts of modern agricultural systems. Use supporting evidence to back up your argument. Then discuss at least two credible lines of argument, with supporting evidence, that raise environmental concerns about specific GMO-based agricultural practices.  (25 points)
