Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.

Many people who want to reduce their ecological footprinthave focused on how much energy is expended (and howmany climate-warming greenhouse gases are emitted) intransporting food from its place of production to its place ofsale. The typical grocery store item is shipped by truck, air,and/or sea for many hundreds of miles before reaching theshelves, and this transport consumes oil. This concern over“food-miles” has helped drive the “locavore” movement tobuy and eat locally sourced food.However, food’s transport from producer to retailer, asmeasured by food-miles, is just one source of carbon emissionsin the overall process of producing and delivering food. In2008, environmental scientists Christopher Weber and H. ScottMathews conducted a thorough life-cycle analysis (p. 400) ofU.S. food production and delivery. By filling in the table below,you will get a better idea of how our dietary choices contribute toclimate change. After measuring mass, energy content, and dollar valuefor each…
