Part One:
The Desert Landscape.Vast open spaces and sun-flooded sandy plains.Craggy peaks thrust out of the desert soil, with cloud masses rolling east across the desertscape, only to disappear in the hot, dry air.It is a place of seeming emptiness, and yet filled with life. This week, we are going to take a closer look at deserts.
To complete this discussion board, you must first read Chapter 12 in your textbook, on Arid Lands, Wind, and Desertification.Then, read the attached short essay by southwestern writer Craig Childs.
Drawing either from the textbook or from your own knowledge of the desert, write a three paragraph essay on an issue that is affecting a desert ecosystem near where you live.Some examples may include: water rights for communities on the Colorado River, the competing water needs of agriculture vs. rural/urban communities vs. wildlife; overgrazing, ATV/recreational vehicle use, etc.Make this personalwhat do you believewhat do you know?/p pDeserts are constantly changing.They grow and recede seasonally through changing wind patterns, and (over thousands of years) may disappear entirely or move and expand hundreds of miles due to changing climatic conditions.For those of us who love the desert, this may not sound like such a bad thing, and yet changing climatic conditions and desertification will have an impact on global food supply.

Part 2:
Instructions: This portion of the Discussion Board will involve external research and a self-debate on the issue of whether/whether not to drill offshore on the North American continental shelf.
Complete Internet research on the issue of whether or not to drill offshore, including the 2010 Deep Horizon oil spill. Be sure to research both sides of this issue.
Conduct a self-debate. That means you will debate this issue with yourself. To do this, youll need to present an argument for/against drilling. Begin with a FOR statement and include the reasons you support drilling. Be sure to include at least one citation to back your argument. Then provide an AGAINST statement and include at least one citation. /span/li lispan style=”line-height: 1.4;”After the self-debate, write a few sentences on your stance/position on this issue as a conclusion to this exercise. The opinion must be academic and not vitriolic. This is not a platform to expound your personal or political beliefs, instead your conclusion must be based on your debate. What is the logical conclusion (e.g., what would the character Spock from Star Trek would do?)./span/li /ol pstrongspan style=”line-height: 1.4;”PART 2.
