Natural Impacts Artificial Impacts Impacts on Air Impacts on Water Impacts on Land

In this unit, we will have an overview of the various natural and artificial impacts on air, water, land. Before we proceed you have to understand that impacts are created by both nature and man. But the impacts of man are more pronounced. In this unit, we shall only mention the various impacts which the student may be already aware. A detailed study of these impacts is the scope of the topic “Stress on physics, chemistry and biology of water owing to impacts”. Therefore in this chapter, the impacts of nature and man on air, water and land would be listed.
