Conservation status of specieschanges often as new threatsarise and current threatssubside. Fish and marine lifeare often threatened by humanactivities such as overfi shing,pollution of ocean and freshwater habitats, and climatechanges.

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…
Recent research has suggested that globalwarming is contributing to the increased fre-quency and severity of El Niño events. Thiscan cause severe drought in India andAfrica, as well as greatly reduce fish catch inparts of the Southern Hemisphere. Shouldthe responsibility for decreasing greenhousegas emissions be greater for more-developedcountries (MDCs) because they produce agreater amount of greenhouse gases percapita than less-developed countries(LDCs), even though El Niños have moresevere consequences for LDCs? Aside from the recent increases in gasolineprices, would you consider buying a morefuel-efficient car or spend more on planeflights to purchase "carbon credits" to doyour part in decreasing the emission ofgreenhouse gases such as carbon dioxide?Why or why not?
