Draw the hydrologic cycle. NO CUT AND PASTE IMAGES. Label at least 12 features. 2) With respect to water consumption… a) What category of human water use is the single largest consumer of water in the world, the United States, and California? b) This category of human water use is approximately what percentage of the water consumed in California? c) What is the single greatest consumptive use of water in the municipal sector in the Western US, and about what percentage of total municipal water use could be eliminated if people stopped this use entirely? 3) The Clean Water Act (CWA) regulates point-source discharges of pollution to Waters of the United States (WOTUS). a) What is the definition of a point-source of pollution and what are two examples that are regulated under the CWA? b) What major category of pollution is excluded from regulation under the CWA? c) Finally, the water bodies that are considered WOTUS has been litigated for decades. Despite this, what are the three kinds of water body that have been consistently considered as WOTUS? 4) With respect to Common Pool Resources (CPRs)… a) What are the two defining characteristics of a CPR? b) Name three examples of CPRs and explain how they fit the definition. 5) With respect to the Tragedy of the Commons… a) What is the Tragedy of the Commons? b) Why can the Tragedy of the Commons arise? c) Regardless of the methods used to address the Tragedy of the Commons, what core feature will all solutions have when the CPR is a potentially renewable resource? 6) Countries use energy from different sources in different proportions. Using at least three countries as examples, explain how geography, climate, geology, economics, and/or politics interact to produce different national energy mixes. 7) With respect to Fossil Fuels… a) Fossil Fuels currently comprise approximately what percentage energy use in the United States? b) What are the major uses of coal, oil, and natural gas? c) At current global consumption rates and assuming only proven reserves, about how much longer would each of the major fossil fuels last on the planet (include both unconventional and conventional oil and gas)? d) What are some factors that could increase or decrease these lifespans? 8) Nuclear power, as the technology is currently deployed, has been promoted as a replacement for fossil fuels. a) Name at least two pros and two cons of nuclear power as a substitute for fossil fuels. b) If nuclear power fully replaced fossil fuels, would we still need to develop other energy sources? c) Why or why not? 9) With respect to Renewable Energy… a) What is the definition of a renewable resource? b) Renewable energy sources currently comprise approximately what percentage energy use in the United States? c) What is the major use of wind, solar, and hydropower? d) Name at least two pros and two cons of switching to renewables vs. fossil fuels. 10) The US EPA regulates six criteria pollutants via the Clean Air Act. Fill out the table below describing what those pollutants are, what their major sources are, and three of the environmental and public health concerns from these pollutants. Criteria Pollutant Sources Concerns 11) With respect to Carbon Dioxide… a) Is CO2 a pollutant that can be regulated under the Clean Air Act? b) Why or why not? 12) With respect to reducing pollution… a) How does a cap and trade system work? b) Say a regulator requires there to be no more than 10 tons/yr of Phosphorus to be discharged by wastewater treatment plants (WWTPs) in a watershed. Currently, the WWTPs discharge the following amount of Phosphorus: WWTP A: 4 tons/yr WWTP B: 4 tons/yr WWTP C: 2 tons/yr WWTP D: 2 tons/yr The regulator assigns credits to each facility allowing them to discharge a certain amount of phosphorus. In this case, they are all the same size so they all get the same amount of credits: 2.5 tons/yr. What might each WWTP do under this scenario?
