Define genetic engineering and distinguish between it and crossbreeding through artificial selection. Describe the second gene revolution based on genetic engineering. What is a genetically modified organism (GMO)? Summarize the growth of industrialized meat production. What are feedlots and CAFOs? What is a fishery? What is aquaculture (fish farming)? Explain why industrialized food production requires large inputs of energy. Why does it result in a net energy loss?
