1:  What is the population density of Bangladesh in m2/person (hint: there are 1,0002, or 106, m2 in a km2)?

2:  What is the population density of the continental United States in m2/person?

3:  The population of Dhaka, Bangladesh was 8 million in 1998. First, calculate the doubling time (i.e., when the population will increase to 16 million) at the 1998 growth rate of 6% per year, using the doubling time formula, t 70 r (see Appendix 1). The population was estimated at 10.8 million in 2008. How did this agree with the value you calculated from your use of 1998’s growth rate?

4:  Using the 2008 growth rate of 3.9%, estimate when the population of Dhaka will reach 21.6 million (i.e., double the 2008 population).

5:  Bangladesh is a trivial producer of CO2 compared with nations like the United States and China, and it faces potential disaster from sea level rise because of global warming and tropical storms. What responsibility, if any, do you believe the main carbon-emitting nations have to reduce the potential for environmental disaster in Bangladesh?

6:  Discuss whether you think protecting marine ecosystems should be a priority for Bangladesh. What measures could they take?

7:  Assume that the United States is at least partially responsible for the potential environmental disaster in Bangladesh. List as many actions as you can, by priority (if you can), that the United States could take to prevent, postpone, lessen, or clean up environmental damage and resultant destruction of property and loss of life.

8:  Summarize the main points of this analysis.

9:  Determine annual rate of population growth for Miami for the period 2000–2007. Use the equation r [(N N0) N0] # years, introduced on page 94–95.

10:  Use the annual growth you calculated in Question 2-9 to determine the doubling time for Miami’s population. Use t 70 r (see Appendix 1).

11:  Using the doubling time you just calculated to project what the population will be in three doubling periods, starting in 2000.

12:  Miami Dade County had a 2006 population of about 2.4 million on a land area of 6,000 km2. Calculate the city’s population density in m2 per person (recall that 1 km2 106 m2). Compare it with that of Bangladesh from Question 2-1.

13:  Examine Figure I 2-2A and I 2-2B. Given the likelihood that a 1.5-m sea level rise could occur as early as the turn of the century and that a 5-m increase in sea level is projected to follow if the Greenland Ice Sheet melts, what measures would you take now to prepare?

14:  Summarize the main points in this Issue.

15:  Where is the proposed development to be situated?

16:  What “need” is the development planned to satisfy?

17:  How did former Miami offi cial Carlos Jimenez describe his view of the proposed site without the development? How do you respond to his characterization?

18:  Recall Chapter 5 on sustainable oceans. What type fuel do marine vessels use? Assess the impact on the local Biscayne Bay environment after the development has opened for business.

19:  What is the problem facing Florida Bay described in the program?

20:  What part of the Bay is affected?

21:  Describe the bloom and its effect on bottom seagrasses.

22:  How is the local Bay’s food chain affected by the bloom?

23:  How could the Florida Transportation Department have contributed to the problem?

24:  What has been the response of the Transportation Department to these allegations?

25:  What was the observed response of the bloom to the reduction of sunlight in the winter?

26:  Describe the lingering effect of the 1989 algal bloom on another part of the Bay.

27:  What has been the practical effect six years after passage of the “massive” Everglades Restoration Plan?
