Patterns of Organization
Read the selection to determine the patterns of organization and the signals used to indicate the pattern.
The Atlantic shoreline is constantly changing and subject to powerful natural forces, such as hurricanes and severe winter storms. In addition to this natural evolution, the shoreline has been harmed by human exploitation. The building of resorts and beach homes alters the natural environment, narrowing the actual beach areas and eliminating the natural dunes, plants, and marshes. The first effect of rapid building and overdevelopment is that wide expanses of beach are eroded, leaving only narrow strips of sand and few sand dunes, ridges or barriers of sand. Unfortunately, when a hurricane or winter storm pounds the narrow, flat sandy beach, more damage is done. The second effect of beach overdevelopment is a loss of natural vegetation. This vegetation also serves to hold the sand, which in turn blocks and absorbs the shock of heavy rains and winds. Although the storms will continue to change coastal environments, erosion can be lessened if people would build wisely, well away from the shore.
