This P.P.T. will tell you about Global Warming,What are the Effect,Facts & How can we Prevent Global Warming.

2. What is Global
Warming?
1.The gradual increase in the
temperature of the earth's
atmosphere
2.Believed to be caused by the
greenhouse effect

3. What is the Greenhouse
Effect

14. •Global warming is the increase of Earth's average surface
temperature due to greenhouse gases, such as carbon dioxide
emissions from burning fossil fuels or from deforestation, which trap
heat that would otherwise escape from Earth.
•Greenhouse gases keep heat close to the
earth’s surface making it livable for humans and
animals. However, global warming is happening
largely to an over-emittance of these gases and
fossil fuels (natural oil, gasoline, coal).
•With the start of industry in the 1700s, humans began
emitting more fossil fuels from coal, oil, and gas to run our
cars, trucks, and factories. By driving a “smarter” car, you
can not only save on gas, but help prevent global warming.
•There is more carbon dioxide in the
atmosphere today than at any point in
the last 800,000 years.
The shifting of the earth’s plates in the Indian Ocean on Dec. 26, 2004
caused a rupture more than 600 miles long, displacing the seafloor above
the rupture by perhaps 10 yards horizontally and several yards vertically.
As a result, trillions of tons of rock were moved along hundreds of miles
and caused the planet to shudder with the largest magnitude earthquake
in 40 years.

16. 2. Use Your Car Less
As we know, air pollution is depleting the ozone layer and therefore
causing global warming. So if you could use your car less by
carpooling with a friend, riding your bike, or taking the bus (which is
at least better than using your car because it holds a large number of
people), then the world could be a much better place. Also, polar bears
will still be around.
3. Conserve Energy
You can do this by turning off any electronic appliances you are not using. If
you're not using something, then turn it off! When I leave my room, I've
made it a habit of turning off the lights. And every time the TV is left on, I
turn it off. Doing this conserves energy and therefore does not waste our
planet's valuable resources.
4. Conserve Water
Yes, I am guilty of taking insanely long showers in the
morning, too, but now I try to limit them to, like, 10 minutes max.
Also, it really bugs me when people are brushing their teeth and they
leave the sink on while their doing it. Please turn off the water when
you're not using it! Yeah, there's a lot of water on the earth, but don't
take our rich resources for granted. We are one of the few places that
has clean water.
