these slides are to save water and our environment , which polluting by various actvities.

2. 1.WATER CRISIS IN
INDIA
 Many parts of India do not
getting proper water for their
family needs.
 People not getting safe water.
 They do fight to get enough
water.
 Water label of safe water is
decreasing.

3. Reasons of water crisis
 Man-made crisis.
 Over-pumping :- lack of law
managing the extraction of
groundwater.
 Population growth:- as number
people increases the demand of
increases.
 Pollution:- industrial waste, Rivers
Sewage System.
 Global warming:-chaotic whether
pattern.

4. What we can do to stop Water
Crisis?
 We should use water carefully.
 We can stop dispersion of god
idols into
the rivers.
 By stopping
throwing of factory
wastes into the rivers.
 We should stop washing cloths in rivers
 Throwing of dead bodies into the rivers.

5.  If we continuously use
water carelessly then in
the coming years we will
not have water to drink.
 We should not do
overuse of water.
 We must try to save
pure and safe water as
much as we can.

6. 2. CLIMATE CHANGES
Climate change is a significance and
lasting in the statistical distribution of
whether patterns over periods ranging
from decades to millions of years.

7. Factors affecting Climate
Natural
factors
• Variations in the
sun’s output.
• Volcanic
eruptions.
Human
activities.
• Deforestation.
• Air Pollution.
Atmospheric
conditions.
• Composition of
gases.
• Evaporation.

8. . Variations in the sun’s output
 Sun radiates solar
energy, which
reaches down to the
earth. But
sometimes these
rays become more
larger. This lead to
increasing
temperature. And
rise in temperature
leads to Global 7/6/2014

9. .Volcanic
Eruptions.
 Volcanic eruptions
generate disturbances
in Earth’s tectonic
plates which leads to
Tsunami.
 Volcanic eruption also
produce many gases
in the atmosphere
which leads to Air
Pollution.

10. .Deforestatio
n
 Excessive cutting of
trees on large scale is
termed as
Deforestation.
Deforestation disturbs
water cycle which
affects the atmospheric
composition . It causes
floods , soil erosion and
also effects our
ecosystem.

11. . Air Pollution
 Un-burnt particles of
gases like Carbon-
dioxide releases in our
atmosphere through
factories, automobiles,
household fires, etc. they
disturb atmospheric
composition and leads to
Global Warming and
Increase temperature.

12. . Composition of
Gases
 Our atmosphere is a mixed
composition of gases. When this
composition disturbs it causes
rapidly changing in climate . It
leads to floods, rise in
temperature, rising of sea-level ,
etc.

13. . Rate of
Evaporation
 Rate of evaporation means
evaporation of water in per second. If
rate of increase then there will we high
rainfall . And may causes floods.

14. What we can do to maintain
Climate?
 We can grow more and
more trees.
 We should use vehicles with
C.N.G gas.
 We should not burn plastic
bags.
 We should not use the
things which produce
carbon-dioxide and other
gases which disturb our Air
composition.
 We should reuse plastic
bottles.
