GLOBAL WARMING

 Introduction to Global Warming:

Global warming is the gradual increase in the temperature of the earths atmosphere due to increased levels of carbondioxide, chloroflurocarbon, and other substances known as green house gases. Global warming, increases the average temperature of the temperature, oceans and landmasses of the earth. The planet has warmed (and cooled) many times during the 4.5 billion years of its history. At present earth appears to be facing a rapid warming, which most scientist believe results at least in part, from human activities.

 Causes of Global Warming:

The main causes of global warming are thought to be the burning of fossil fuels, such cool, oil and natural gases and other substances known as green house gases. There are other gases as well which take part to increase the temperature of the world, and they are: increase carbondioxide, chloroglurocarbon, sulphur dioxide, etc. There are very harmful components. The other known causes of global warming is pollution.

 One of the thing which take part in global warming is pollution. Pollution, contamination of earths environment with materials that interfere with human health, the quality of life or the natural functioning of ecosystem (living organisms and their physical surroundings). Although some environment pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities. Pollution is changing earths atmosphere so that it lets in more harmful radiation from the sun. At the same time, our polluted atmosphere is becoming a better insulator, preventing heat from escaping back into space and leading to rise in global average temperature scientist predict that the temperature increases referred to as global warming, will affect world food supply, alter sea level, make weather more extreme and increases the spread of tropical diseases.

 Effects of Global Warming:

As we know that global warming is very dangerous to every living creatures in the world. Due to global warming the snows are melting and the sea are rising an inch every year. Due to the rising of sea level many island of Maldives has already disappeared. Due to global warming the ozone layer has got hole in it. Due to the hole of ozone layer, the UV rays of the sun comes direct in the surface of the earth and it causes diseases like skin cancer, damages our eyes etc. It forms new diseases as well and the recent formed new diseases are bird flue, swine flu, etc.

 Prevention of Global Warming:

Global warming is very serious problem that the world is facing now. I think we should all plants trees (afforestation) and stop deforestation. Pollution should be reduced. We should not use gases like chloroflurocarbon, carbondioxide, which causes depletion in the ozone layer. Population should also be managed. Plastic should not be used. Alternate source of energy such as solar, wind power, etc. should be used instead of fossil fuel such as coal, oil, to reduce global warming.
