Study Guide Questions

Humans in the Landscape: An Introduction to Environmental Studies

Chapter 1

  1. How have the activities and range of individual humans and families changed over the past 200 years?
    • In the past, people lived in one place for their whole life.
    • They ate food from gardens nearby.
    • They wore clothes made from fibers grown in villages near them.
    • By the year 2000, economic development changed peoples activates.
    • People’s material livelihoods are no longer local. Imported from many countries.
  2. How have the impacts of humans on ecosystems changed in the past 200 years.
    • These changes have environmental implications, such as the greenhouse gas emissions.
    • Wiping out plants and animal species.
    • Changing weather patterns.
    • Transforming landscapes.
  3. What is the ultimate question that must be faced at this time if we are concerned about the world 25-50 years from now?
    • Will our environmental system be sustainable in the next 25-50 years from now?
  4. In which year will you be 70 years old? If you have children, in which year or decade will he/she/they be 70 years old?  If you have grandchildren, which decade are they likely to be 70 years old?  Is it possible that you could have great grandchildren and in which decade could that be?
    • I will be 70 in year 2063.
    • My son will be 70 in year 2086.
    • No grandchildren.
  5. What problems do the authors describe as grand problems?
  • Climate, biodiversity, urbanization, sustainable development.
  1. On page 6, the authors state that the issues on the Channel Islands off the coast of Southern California help us to “…begin to see the ways in which local events are connect to the global forces of human society.” What is the evidence and what are the details they present for this insight?
    • Three events at different space and time together caused the population of the Channel Island fox to decline. The introduction of the feral pigs, the decline of valuable plants from the use of pesticides, or urbanization was not the fox problem.
    • Human actions had altered the patterns of nature in each of these ecosystems. When the altered patterns overlapped, the number of Channel Island fox declined.

Sustainable & Green Manufacture


Sustainable & Green Manufacture

#1 Between 1980 and 2000, the average CO emission factor of the vehicle fleet in Hillsborough County, Florida, dropped by almost half, from about 65 to 34 g/vehicle-mile. However the total miles driven in the county by all vehicles increased by 60 percent during this same time period. Did countywide emissions of CO go up or down, and by how much (Assume   0) ? Vehicle exhaust is getting cleaner through a combination of engine improvements, emission control technologies, auto re-design, and fuel reformulation, but what other solutions can you think of?

#2 Determine or estimate your personal energy use. (KWh, gallons gasoline, mcf natural gas, air travel miles etc.) Access one of the reputable Carbon (Dioxide) Inventory websites, enter appropriate data, and get CO2 E results. Document your results in a table. Comment on the results and compare your CO2E to U.S with the average emissions per person in the United States and compare your CO2E to world average of 1 MTCO2E/person/year. To get the most accurate results, you need to gather your recent electric, gas, and/or oil bills so you can use real numbers for your household’s energy consumption. Remember that your energy bills vary by season, so use an average of winter and summer values if you can. You can use this website: http://www.epa.gov/climatechange/ghgemissions/ind-calculator.html

#3 In 2007, the weighted average combined fuel deficiency of cars and light trucks in the United States, combined, was 8.67 km/L. The average vehicle traveled 18,861 km in 2007. The amount of CO2 emitted per gallon of gasoline burned is 8.92 kg. Assume for the following calculations that the 2007 data are applicable to all registered vehicles. In 2010, there were nearly 32 million registered vehicles in California. a. Calculate the emissions of CO2 from California in 2010. b. It is estimated that there were approximately 250 million registered vehicles in the United States in 2010. Calculate the emissions of CO2 from all automobiles in the United States in 2010. c. By the year 2050, it is estimated that there will be perhaps 300 million automobiles in the United States. If this happens, and we assume driving conditions stay approximately the same, what would the CO2 emissions from automobiles be in 2050 in the United States? d. In 2012, India was estimated to have about 15 million automobiles. While driving conditions and automobile types in India are much different from those in the United States, what will the emissions of CO2 be from automobiles in India if the gas mileage and driving patterns were the same as those in the United States? e. By the year 2050, India is expected to be the largest automobile market in the world. Goldman Sachs has estimated that there will be more than 610 million automobiles in India by 2050. If this happens, and we assume driving conditions stay approximately the same, what would India’s CO2 emissions from automobiles be in 2050? f. Create a bar graph illustrating the number of vehicles and CO2 emitted from scenarios in parts (a) through (e). Note: – show your calculations to receive credit – Must be typed and submitted using Microsoft Word format ONLY and copy and paste your bar chart from your Excel sheet to the word document?
