Pollution started from prehistoric timeswhen man created the first fires. According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.
Each year, erosion costs billions of dollars in loss of land productivity, damage from soil sediment deposition and subsequent restoration costs, and harm to plant, animal, and human health due to air and water pollution.
This lesson will consider the impacts of erosion at local, regional, national, and international levels. It will discuss how erosion occurs and the main factors that contribute to erosion.
In addition, the different types of water and wind erosion will be discussed. The lesson is written to target educational needs of lower level undergraduate students and is open for use by the public and educational institutions.

Upon completing this lesson, a student should be able to: Describe the impacts of erosion on soil, water, and air quality. Describe the processes in water and wind erosion. Identify and analyze factors contributing to water and wind erosion of soil.
Identify and describe the types of water and wind erosion. These self-paced or thinking questions are intended to generate discussion.
They can be used in classroom small group discussion. If the course is distance and the lesson is used to support course objectives, they can be used as online discussion threads.
Objective-based questions focusing on the fundamentals or principles of soil erosion and its impacts can be developed as an assessment tool. A local, national, international erosion problem can be used as a case-study project for students to apply erosion and erosion control principles.The effects of human activities on the quan- Contaminants may be present in water or in air as a result of natural processes or through mechanisms of displacement and dispersal related to human activities.
