BARRIER ISLANDS: TO BUILD OR NOT TO BUILD?

-adapted from Glencoe webquest 9/06

Introduction

If you look at a map of the eastern shoreline of the United States, you can see that the Atlantic and Gulf Coasts are lined by a series of thin, elongated islands. These islands are known as barrier islands because they provide barriers to winds and ocean waves. These islands protect the mainland by absorbing the energy produced in hurricanes and normal winter storms. But barrier islands are not just important geological features. They also are unique ecosystems.  These ecosystems provide feeding, mating, and nesting areas for shorebirds, commercial fish species, and shellfish such as clams, oysters, and crabs. These beaches, dunes, and wetlands also provide important recreational activities for people. The different uses of barrier islands result in disagreements about how they are to be managed. Should barrier islands be protected and left undeveloped? Should people be allowed to build homes and hotels on barrier islands?

 

Task

Your job in this WebQuest is to develop an educated opinion as to whether or not people should build permanent structures on barrier islands.  Once you have done your research, you will prepare a "letter to the editor" of a newspaper in which you outline what you have learned about barrier islands and state your opinion on whether permanent structures should be built there. Your letter should include information about the geology and ecology of barrier islands as well as the changes they are subject to. Your goal is to convince readers of the newspaper that your conclusion is correct through educated arguements.

Process

Now that you have completed your research on the Internet, decide what you think should be done with barrier islands. Should these islands be developed? What types of development should be allowed? Should any kind of development be prohibited? Write a "letter to the editor" in which you develop your answers to these questions. Support your opinion with information from your Internet research. All questions above should be addressed in your letter to the editor.
