global warming and it's detail in very simple language

1. Global Warming is the increase of Earth's average
surface temperature due to effect of greenhouse
gases, such as carbon dioxide emissions from
burning fossil fuels or from deforestation, which
trap heat that would otherwise escape from Earth.

2. The greenhouse effect is a natural process
that warms the Earth's surface. When the
Sun's energy reaches the Earth's atmosphere,
some of it is reflected back to space and the
rest is absorbed and re-radiated by
greenhouse gases.

4. 1. Burning of Fossil Fuels
2. Deforestation
3. Increase in Population
4. Farming
5. Industrial waste and landfills

5. Fossil fuels like coal, oil and natural gas have
become an integral part of our life. They are used
on large basis to produce electricity and for
transportation. Pollution which gets emit from
vehicles contains carbon di oxide, which is one
the main gas responsible for increase in
greenhouse effect. Apart, from that, the
production of electricity consume too much of
coal which releases large amount of these gases
into the atmosphere.

6. Forests holds a major green area on this earth.
Plants and trees intake carbon dioxide and release
oxygen, through the process of photosynthesis,
for the survival of human beings. Large scale
development have forced people to look for
alternate places for living which has resulted in
cutting down of trees. The wood that is produced,
when burnt releases more carbon dioxide into the
atmosphere.

7. Over the last few decades, there have been huge
increase in the population. Now, this has resulted
in increased demand for food, cloth and shelter.
New manufacturing industries have come up
release some harmful gases into the atmosphere
which increases the greenhouse effect. Also, more
people means more usage of fossil fuels which in
turn has aggravated the problem

8. Nitrous oxide is one the greenhouse gas that is
used in fertilizer and contributes to greenhouse
effect which in turn leads to global warming.

9. Industries which are involved in cement
production, fertilizers, coal mining activities, oil
extraction produce harmful greenhouse gases.
Also, landfills filled with garbage produce carbon
dioxide and methane gas contributing
significantly to greenhouse effect.

10. Well actually the greenhouse effect is a natural process of nature. If
there was no greenhouse effect then we would be living in an ice age
because there would be no greenhouse gases to trap the heat.
By releasing more greenhouse gases into the atmosphere (like CO2,
CFCs, methane), the effect of greenhouse effect increases causing
greater heating than what is supposed to occur.
So greenhouse effect cannot be prevented but can only be REDUCED.
1. By reducing emissions from automobiles, the greenhouse
gases can be reduced.
2. By preventing deforestation, because plants absorb a great
amount of CO2 from the atmosphere.
3. By using CFC-free refrigerators (almost all the newer models
of fridges are CFC free nowadays).
4. By reducing use of aerosols because they produce CFCs.
