Violent conflicts are often in the news. Seldom do the environmental consequences of such conflicts make the news. As new weapons become more and more toxic, should the environmental consequences play a role in decision-making? Why or why not? The World Trade Center collapse had a devastating effect on the city of New York and its people. Does an event like this make a difference in your thinking? Why or why not?
What will be an ideal response?
The answer is highly subjective. A useful approach would be to consider what remains on a battlefield, rendering the environment hazardous and/or toxic. The reality that people have to try to reconstruct their lives in such situations may provide insight into the problem. Except for the WTC, conflicts have been distant events for most U.S. citizens. If it was our environment we might be more interested in what remains.

To the west of Hollybrook (south of Lake Providence along Highway 65), find the streams named “Otter Bayou” and “Swan Lake.” What kind of floodplain landform explains the curved paths taken by these streams? (Hint: The landform is too low to be shown with this map’s contour interval.)
The question is based on Map T-5, a portion of the “Jackson, Mississippi-Louisiana” topographic map (scale 1:250,000; contour interval 50 feet; dashed lines are supplementary contours at 25-foot intervals). A color satellite image of this same region is shown in Figure 40-5 (scan the QR code for this exercise or go to the Lab Manual website and Exercise 40). For reference, the dashed contour line on “Paw Paw Island” in the southern part of the map shows an elevation of 75 feet. What will be an ideal response?
