It's about global warming. and it contains about pollution too.

1. Man did not weave the web of life- he is merely
a strand in it.
Whatever he does to the web, he does to
himself

3. • Environmental Pollution
– Water pollution
– Land pollution
– Air pollution
• Global Warming
– What is global warming?
– What is green house effect?
– Consequences of global warming
– How to reduce global warming?
– What we can do for reduce?

4. • Mainly there are three types of environmental
pollution.
They are
Land pollution
Water pollution
Air pollution

5. • Land is the place where human and all the
other living beings are living.
• In the Earth we have only 25% of landscape
for living.
• Though we have 25% of landscape we can’t
live all the space that we have.

6. • Land pollution is another major
issue in Environmental
pollution
• It harms all the human beings
and whole environment
• Mostly it is caused by human
activities.
• There are different sources for
land pollution.

7. • Increasing mechanization
• Pesticides
• Mining
• Increasing waste disposal
• Increasing non-biodegradable waste
– Plastic
– Glasses
– Etc..

8. • Increase in urbanization.
• Increase in agricultural land
• Domestic waste
• Increase in urbanization.
• Increase in agricultural land
• Domestic waste

9. • Exterminate the wildlife.
• Acid rain kills trees and other plants.
• Trees that provides food and shelter is
destroyed.
• It can seriously causes the balance of
nature, and, in extreme cases, can cause
human too.
• Pesticides can damage crops, kill
vegetation, and poison birds, animals, and
fish.

10. • Encourage farmers for organic farming
• State proper garbage disposal
• Recycle garbage
• Reduce use of pesticides

11. • Water is one of our basic needs in our life.
• ¾ of our world is covered by the water ,so that
our world is called as water planet.
• The world has various types of water but we
used only 1% of it.
–Oceans water -96.5%
–Ground water -1.7%
–Ice caps -1.7%
–In the air -0.001%

12. • Water pollution is the major
issue in the world.
• Water pollution affects drinking
water, oceans, rivers and lakes.
• It’s harms to human health and
natural environment.
• Mostly it is caused by human
activities.
• Water pollution is considered
under two types.
– Point source pollution- pollution comes
from a single source
– Non-point source pollution-pollution
comes from many sources

13. • Waste water - water from domestic and industrial
process.
• Agricultural - agricultural processes such as tillage
pollution ,use of pesticides, fertilizers.
• Oil pollution - oil leaks from ships, oil from factories
• River dumping – dump of garden cuttings, electronic
waste
and steal products.

14. • Poisonous drinking water- causes many
diseases
• Poisonous animal’s food- kills fishes
• Acid rain
• Unbalanced river and lake ecosystem
• Disrupts the natural food chain
• Disrupts water cycle
• Biodiversity loss

15. • Filter the water when
drinking.
• Releasing water from
factories after cleaning.
• Decrease the use of
chemicals for agricultural
needs.
• Checks the places where oil
leaks in ships.
• Stop dumping in sea and
river.
• Create an act to stop
polluting water.

16. • The earth is surrounded by the air.
• It’s contains oxygen which is essential for us to
live.
• It contains
– Nitrogen
– Oxygen
– Carbon dioxide
– Water vapor and other oxides.

17. • How it happen?

18. • Gases from factories and vehicles.
• Wildfires
• By sending rockets
• From war places

20. • Difficult to breath.
• Bio diversity loss.
• It is causes diseases .
• Poisonous air.
• Harmful to Orson (O3) Layer
• Both N2 and CO2 Cycles are going out of order
• Increase the percentage of Greenhouse
Gasses

21. N2 Cycle

22. • Use public transport to reduce the number of
vehicles.
• Growing trees around the house to produce
oxygen.

24. • Global warming is rising average
temperature of Earth's
atmosphere and oceans.
• It happens when greenhouse
gases trap heat and light from
the sun in the earth’s
atmosphere, which increases the
temperature. This called green
house effect.

25. • Sunlight brings energy into the climate system; most of it is
absorbed by the oceans and land.
• Heat (infrared energy) radiates outward from the warmed
surface of the Earth..
• Some of the infrared energy further warms the Earth.
• Some of the infrared energy is emitted into space.
• Harmful to Orson(O3) Layer

26. Some solar radiation reflect by
the earth and atmosphere
Most radiation is absorbed
by the earth surface and
warm it
Solar radiation
passes through the
atmosphere
Some of infrared
radiation is absorbed
and re emitted by the
green house gas
molecules
Tradition is
converted to heat

27.  Carbon dioxide (CO2)
 Methane (CH4)
 Nitrous oxide (N2O)
 Hydro fluorocarbons (HFCs)
 Per fluorocarbons (PFCs)
 Sulphur hexafluoride (SF6)

28.  Increase temperature.
 Melting ice and glaciers.
 Rising sea level.

29.  Habitat damage and species affected.
 Ocean acidification.
 Coral reef destruction
 Hurricanes, droughts, extreme weather.
 Increase in human death and disease.

30.  Wind power
 Solar power
 Fuel efficiency
 Recycle

31.  Conserve energy:
 Buy energy efficient products
 Buy products that have reusable or recyclable
packaging
 Reduce use of car (walk instead)

32.  Turn off the computer or TV when you are not
using it.
 Keep rooms cool by opening shutters and
reducing the use of air condition.
 Use compact fluorescent bulbs.
 Turn off lights and fans when you leave a room.
 Plant trees.

33. • Environmental pollution and it’s sources
• How to reduce those pollutions?
• What is global warming?
• Consequences of global warming
• How to reduce global warming?
• What we can do for reduce?

34. • The warnings about global warming have
been extremely clear for a long time. We are
facing a global climate crisis. It is deepening.
We are entering a period of consequences.
AL GORE, speech at National Sierra Club Convention, Sept. 9, 2005
• Therefore we all need to participate to reduce
GLOBAL WARMING!!!
