What causes Global Warming?Deforestation and pollution result to

an increase greenhouse gases (such as carbon-dioxide) around earth’s atmosphere.

These greenhouse gases traps and absorbs

atmospheric heat and ultimately causes GlobalWarming (an increase earth’s surface temperature).

Causes OF Global Warming?

THESE GREENHOUSE GASES

POLLUTION DEFORESTATION

DEFORESTATIONDeforestation, clearance

or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use. Tropical rainforests is where the most on centrated deforestation occurs.

POLLUTION Pollution is derived from

Latin word "polluere" which means to defile. Pollution is an undesirable change in the physical, chemical or biological characteristics of our air, land and water that can harmfully affect human life or that of other species, our industrial processes, living conditions and cultural assests. 

GREEN HOUSE GASESA greenhouse gas is any

gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for thegreenhouse effect, which ultimately leads to global warming

How to prevent Global Warming?The problem of Global Warming can be controlled by minimizing the emission of greenhouse gases into the environment. The following preventive steps would help save the earth from the harmful effects of Global Warming.

LawsThe Laws that governs pollution and greenhouse gases should be followed.

Reduction in thermal power generating stations

 Reduced dependence on thermal power for our electricity need would help towards reducing the quantity if carbon dioxide in the environment. The use of fossil fuels for generating conventional energy is a major of greenhouse gases.

We should not waste paper We can save paper by

keeping documents in electronic format and by not printing emails.

Planting Trees  Trees absorb carbon

dioxide and releases oxygen. Trees are helpful in reducing the problem of global warming.

CAR-PULLSharing our car. We can share our car while going to office or performing other scheduled activities. On one hand, we will save money, and on the other, we will emit less greenhouse gases.

Climate ChangeGlobal warming is causing climate change. The world’s is becoming warmer and warmer. There is also prediction of regional climate changes along the ecosystem.

Sea Level ChangeOne major consequence of global warming arising out of greenhouse effect is the rise in sea level. Four major changes take place prior to this. They are: Thermal expansion, mountain glacier melting, Greenland ice sheet melting and Polar ice sheet melting. Thus, the coastal cities and ports may be submerged under sea-water. Many islands may vanish from the earth surface as well as from the world map.

Water Dis-Balance Although changes in sea-level have received much publicity, problems of water availability are likely to be more serious and perhaps more expensive to solve. In future, warmer world will face water crisis in some parts while in other regions it will be wetter than it is now.

Human Health The human health is

put at risk because of Global warming. In recent years, there have been newer reports of spread of major tropical diseases with changing climate. As the earth becomes warmer, more and more people are likely to be affected by tropical diseases.

In future, on earthIF THE THINGS

DO NOT CHANGE THEN OUR EARTH WILL BECOME A DEAD PLANET IN FEW CENTURIES ONLY.
