The earth is drying up !
Reports from Mumbai that the city has only water for a month, if there are
no rains. Cause for alarm and despondency
Water Cycle or the Hydrologic Cycle
Due to transpiration and evaporation, water molecules form clouds and rains
fall to the earth as precipitation.
This transipration and evaporation normally comes from plants, rivers,
lakes, lagoons, water basins or water reservoirs. If the earth's surface is
paved over, then there will be reduced water to evaporate.
Divesting the earth of wells, lagoons, lakes, rivers which are water
reservoirs can only mean that there will be less evapotranspiration and
hence less precipitation or rains !
The causative factors for Water Bankruptcy
The destruction of the natural habitat
Destruction of water reservoirs like wells, ponds etc
Destruction of forest, flora and fauna
Groundwater mining
Contamination of Aquifers
Massive urbanisation
Diminishing water capital
Earth's hot stains ( dried up regions ) contributing to the impasse
