Water Scarcity
&
Conservation of
Water
Importance of water:• Water is a natural source of water . It
is a habitat for
many plants , animals and human beings. We can live without food for some days , but
cannot live without water. Our earth ‘s ¾ of surface is covered with water of
which 97% of water exists in ocean . It is salty and cannot be used for our daily
needs. The other 3% of water is fresh and can be used for our daily needs .
Water Scarcity
 :- As we know that the level of fresh is low .But now, the level
of this water is decreasing and hence there is Water scarcity.
Factors
causing Water Scarcity:-
1:Enviromental Degradation:- Rain and Snow are the two major
natural sources of water .But now-a-days, there is a drastic
decrease in both rainfall and snowfall because of climate change
caused by some activities . Deforestation is one of them. Trees are
being cut and forests are being cleared for setting
up factories and building houses. The
another one is Ecological Imbalance
caused due to vehicles . Dust and
harmful gases from vehicles get into
air and mixes with rainwater and
make it acidic .This causes an
Ecological Imbalance.
Factors causing Water Scarcity (contd……)
2: Population:- With the increase in Population in the world ,the
demand of water has also increased. More and more water is
required ,whereas lesser and lesser water is available.
3: Industrialization:- There is also an increase in the number
of industries . Industries use a large amount of water .They get the
most of required water from under ground .This reduces the level
of underground water.
Water Conservation:Now we know that the level of fresh water is limited and it is
decreasing . If we continue to waste and overuse the water carelessly
, a day will come when there will be no water for drinking and crops
will die due to lack of irrigation . So , we should save water . Wise
utilization of water for saving it is called water conservation .
