1:  Where is growth projected to be most rapid?

2:  Go to Issue 2 and review Figure I 2-2 (impact of sea level rise on Miami and Florida). Comment on the long-term implications of growth in these areas on the marine environment.

3:  Do you think insurance companies will continue to provide insurance to homeowners in light of sea level increases? If so, what do you project will happen to rates? If not, how will this impact the responsibilities of the state and federal governments?

4:  Discuss whether you think that state and/or federal government can afford to guarantee rebuilding costs for coastal dwellers.

5:  How did government’s response to Hurricane Katrina affect your answer to Question 3-4?

6:  Study Figure I 3-2, which shows a projected 60-year erosion hazard map, for South Bethany, Delaware. Using the scale, determine how far inland the beach is projected to erode over the next 60 years. What is the average rate expected in feet per year? How many houses will be affected?

7:  If sea level is projected to rise by about 60 cm by 2100, how far inland on average will the coastline move?

8:  A conservative estimate of the projected rise in sea level by 2100 is 60 cm (2 feet). How do you think the typical American perceives the seriousness of a sea level increase of this magnitude over a 90-year period? How do you think this affects their conclusion about the urgency of the problem?

9:  In your judgment, where in Figure I 3-3 is the erosion problem most severe? We are not asking where erosion is most severe but where the problems it causes are most severe. Under what assumption did you carry out this activity?

10:  In the light of limited government revenue and the desire of many to relentlessly reduce taxes and the role of government, to what extent is it an essential responsibility of government to pay, out of general revenue, to protect coastal infrastructure? If it is a responsibility of government, at what level should this responsibility lie? Explain your reasoning, or cite evidence.

11:  Who benefi ts from coastal engineering projects?

12:  Consider the Point-Counterpoint at the beginning of this Issue. First, explain both Brook’s and Pilkey’s positions.

13:  Discuss which of these positions you support. Support your conclusion with evidence.

14:  Summarize the main points in this issue.

15:  How rapidly is the Louisiana coast losing land?

16:  How has human engineering of the Mississippi changed the river’s pattern of sediment deposition?

17:  The state is creating land by dredging silt from shipping channels and dumping it into wetlands. What is the ratio of land “saved” to land that is lost by erosion?

18:  How much sediment is being dumped into the deep Gulf every year?

19:  Describe the proposal to change the course of the Mississippi to protect the coast.

20:  Where are the funds to change the River’s course proposed to come from?

21:  What is the expected impact of the project if carried out on the state’s oyster industry?

22:  How many times has sand been placed on the John U. Lloyd State Park’s beaches since 1970?

23:  What was the source of the sand used to renourish the beach?

24:  How much sand was used?

25:  Why can’t the beaches recover on their own?

26:  Discuss whether you agree with allowing a new condo on the sand that was trapped by the jetty and that thus never reached the state park’s beach.

27:  Why is beach restoration not just a cosmetic procedure?

28:  Discuss whether you agree or disagree with Charlie Finkle’s statement, “We need to keep renourishing the beach to keep up with the rise in sea level and if we don’t keep up with the renourishment, we’re going to fall behind and then you’re going to have bigger disasters.”

29:  List and evaluate the options engineers are considering.

30:  Was “doing nothing” mentioned as an option? What are the advantages and disadvantages of doing nothing?

31:  Coastal geologist Orrin Pilkey has said, “Nature bats last at the shoreline.” What do you think he means?
