Pollution Lecture Powerpoint  Water is an essential component of
life and a vital resource on the Earth. The first part of this
Powerpoint lecture delves into the importance of water, its role
in climate, and its distribution around Earth. The tragedy of
the Aral sea in the former Soviet Union is used as an example of
how water can be misused and eventually completely consumed.
Special attention in this lectureis given to groundwater, which
is the largest sources of freshwater in many regions of the

groundwater, and contrast with the recharge zone of aquifers.

shown examples of different types of water pollution, ranging
from inorganic salts and acids to organics such as sewage.
