ABSTRACT
In the last 50 decades of world history, the American continent has been carrying out the special role of providing the necessary resources for a scientific and technological development of humanity. The intensive ancient world’s advance brought to this geographical space a new organization creating serious socioeconomic and political conflicts, the results of which reflect directly on the natural resources and their environmental structure. The process of contact and the occupational methods utilized by the Great Navigators back in the 15th century resulted in demographic concentrations which now constitute the important urban centers of the American continent. These cities are located very close to marginal areas of coastal systems-the seashore is practically entirely composed of coastal plains adjacent to barrier island complexes.
