Introduction:
The water that we
drink and use for washing and bathing has been in the form of rain
drops at some
point. Rain refills dams and lakes and underground waters. Rain
also irrigates farms and forests. In the history of mankind, many
lakes and rivers have dried, many towns and villages have been abandoned,
and many humans and animals have died because of a shortage of rain and water. |
