JIM BINKO: Our investigation of North Africa/Southwest Asia continues in Egypt. Here as throughout that region, the presence or absence of water has had a profound influence on human settlement.
We will see the great impact that access to resources has on the characteristics, distribution and migration of human population on Earth's surface. You will be able to understand how changes in the spatial distribution of population may result in changes in social and economic conditions. Conditions may include availability of water supply for expanding urban regions, adequate space for extra housing, and opportunities or a lack thereof for education and employment.
Egypt has harnessed the mighty Nile with both positive and negative consequences. This case study shows how human actions modify the physical environment. Here we see the contrast between ancient ways of life and modern technology in a contest for domain over the resources of Egypt.
This drives our second objective: to understand the role of technology in changing the physical environment, and the environmental consequences of such actions. Following the case study, we will observe seventh-grade teacher Cynthia Ryan use Egypt and the Nile as the focus of a classroom lesson.
NARRATOR: From space, the earth can seem an abstract pattern of color and shape. But as we look closer, environmental processes come into view. Here the rain of East Central Africa collects into the giant Lake Victoria. Its waters drain to the north, giving rise to one of the world's great rivers, the Nile.
Descending from the African highlands, the Nile winds through one of the Earth's most arid landscapes. Coursing through the vast desert of northern Africa, the waters of the Nile nourish a ribbon of green across the sun-baked terrain. And 4,000 miles from its source, the Nile puts forth its greatest gift-- a lush and fertile delta that
