Humans, the Environment, and the Great Plains

Watershed Pollution

Background:

Recent trends in watershed pollution indicate that urbanization is having the greatest indirect influence on water quantity and quality. According to the United Nations Conference on Environment and Development (UNCED), if the causes of pollution and waste are not addressed, pollution will worsen as economies expand.

 Objective:

To bring about a greater awareness regarding the growing problem of watershed pollution. The northern Great Plains are presently facing this threat. The result is an adverse impact on the quality and quantity of clean water and the desertification of grasslands.

Plan:

  1. Choose a large body of water (a lake, river, or pond) important to your area of residence.
  2. Ask students to examine the importance of this body of water by addressing answers to the following questions:
    • What is the geography/geology of the body of water?
    • What flora and fauna are characteristic of it?
    • How many people make a living from this body of water?
    • What are their occupations?
    • What events are important in the history of this body of water?
    • Have any archaeological sites been excavated here? If yes, then how far back do they date?
    • What is the condition of water? Is it improving or deteriorating?
    • What is being done to plan for the use of this water?
    • What laws have being passed or are being discussed to regulate the water and surrounding areas 
  3. To obtain this information, students will contact the appropriate state or local agencies, such as the Department of Natural Resources (DNR), the National Park Service (NPS), the State Historic Preservation Office, other local historical societies, museums, foundations, and private groups concerned with preserving that body of water.
  4. Evaluate the environmental, economic, and cultural changes that have taken place in the region where the body of water is situated within the past 100 years.

 Testing, Grading, and Evaluation:

Have students identify sources of watershed pollution. Has the situation worsened over time?
