what are the causes of greenhouse effect ?


Causes of the green house effect:-

1. Deforestation

2. Industries

3. Automobile

4. Population growth etc.

@ All, thanks for answering.

 This effect moderated temperature on the Earth long before humans began changing the chemistry of the atmosphere. Like a well managed greenhouse, the Earth’s surface remained warm, but not too hot, and thus allowed the growth of the lush ecosystems we have inherited. The increase in heat-trapping gases in the Earth’s atmosphere caused by human activity means the greenhouse effect could, like a poorly managed greenhouse that is left closed up on a hot summer day, overheat and do great damage to all the living creatures on the Earth.

Humankind has progressed a lot over the years. However, this progress has come at a cost of the exploitation of nature many a time. Humans are the main reason for the pollution in nature.

Global warming has been a matter of concern for many years, with various man-made machines now contributing to Global Warming.

One of the main causes of Global Warming is the Green house effect. When the emission of infra-red radiation in the atmosphere warms a planet's surface, it is known as the Green House Effect. The Greenhouse effect is a natural phenomena occurring on planet Earth.

There are natural as well as human-made causes of the greenhouse effect. The natural causes of the Green house effect are the emissions of gases like nitrous oxide, carbon-di-oxide, methane, ozone and water vapor.

The life on Earth depends entirely on the Sun. The energy for life is supplied by the Sun. Out of the total sunlight available, more than thirty percent is deflected into outer space. The rest is reflected and converted into slow moving energy called infrared radiation. This radiation is then trapped into the atmosphere by various gases like carbon-di-oxide, methane, ozone and water vapor. Therefore, it's escape is slowed down. Out of these gases, carbon-di-oxide itself is responsible for the Green house effect.

The greenhouse effect is actually beneficial to the Earth. It is only when human-made processes increase its speed that the problems occur. One main problem is the oft repeated 'Global Warming'.

One of the man-made causes of the Green House effect is deforestation. Deforestation increases the amount of carbon-di-oxide in the atmosphere. Also, due to the disappearance of trees, photosynthesis cannot take place. Deforestation causes of the greenhouse effect. Deforestation is rampant today due to the increase in human civilisation. The levels of deforestation have increased by about nine percent in recent times. Also, the burning of wood causes it to decay,therefore releasing more carbon-dioxide into the atmosphere.

Greenhouse Gases also can be released into the atmosphere due to the burning of fossil fuels, oil, coal and gas. These materials are used increasingly and rampantly in Industries. Therefore Industries are also a major cause of the Greenhouse Effect.

Other man-made causes of the increase in the Green house effect is due to the emission of such gases by electrical appliances. Even the humble refrigerator in the house emits gases which contribute to the Greenhouse effect. These gases are known as Chloroflourocarbons (CFCs) and are used in refrigerators, aerosol cans, some foaming agents in the packaging industry, fire extinguisher chemicals and cleaners used in the electronic industry. Some processes of the cement manufacturing industries also act as a cause towards the Greenhouse effect.

Other man-made processes that contribute and are a cause to the Greenhouse effect are burning of gasoline, oil and coal. Apart from these, some farming and land-use processes are a cause of the Green house effect. Most factories also produce many gases which last for a longer time in the atmosphere. These gases contribute to the green-house effect and also the global warming on the planet. These gases are not naturally available in the atmosphere.

Population growth also is a indirect contributor and one of the causes of the Greenhouse effect. With the increase in population, the needs and wants of the people increase. Therefore, this increases the manufacturing processes as well as the industry processes. This results in the increase of the release of industrial gases which catalyze the green house effect. The increase in population also results in the increase of agricultural processes. Most man-made machines, like the automobile also contribute to the green house effect
