1. MEANING OF GREEN HOUSE A greenhouse is a building made by glass sheet where plants are cultivated. In briefly, a greenhouse is a structure with a glass or plastic roof and glass or plastic walls. When the sun’s ray reflects on glass then the house gathers heat by radiation and the house keeps remain hot because the glass blocked the sun rays. In that types of house some plants are cultivated where normal temperature is not enough for cultivate plants. Here is one image of a normal look green house,

2.MEANING OF GREEN HOUSE EFFECT The greenhouse effect discovered by Joseph Fourier in 1824 and first investigated by Arrhenius in 1896. The Earth has a natural temperature control system. Certain atmospheric gases are maintain the system and are known as greenhouse gases. On average, about one third of the solar radiation that hits the earth is reflected back to space. Some is absorbed by the atmosphere but most is absorbed by the land and oceans. The Earth's surface becomes warm and as a result emits infrared radiation. The greenhouse gases trap the infrared radiation, thus warming the atmosphere.

Continue…. Naturally occurring greenhouse gases include water vapors, carbon dioxide, ozone, methane and nitrous oxide, and together create a natural greenhouse effect. However, human activities are causing to increase the greenhouse gas levels in the atmosphere in an extreme stage that so the full process of natural green house is happened massively that is called green house effect. Though the full process is look like the green house so is called green house effect also. Here the carbon dioxide gas is like glass sheet and we are like plants. Here is a simple figure which mentions total process of green house effect,

3. MAIN CAUSES OF GREEN HOUSE EFFECT Human are mainly accused for the green house effect. We know that the enhancement of carbon dioxide in an extreme range is the main reason for green house effect. So from where the carbon dioxide is produced they are the main cause for green house effect. Here some examples are mentioned what are really responsible for producing carbon dioxide, a. Deforestation Plant destruction in a large scale is one of the main reasons for green house effect. Because trees are absorb the Carbon-dioxide and produce Oxygen gas.

b. Increasing of population : A huge number of human produced a huge Carbon-dioxide so it another reason of green house effect. Here is an example for that,

c. Burning fuel: Burning fuel like petrol, diesel, octane, coal and kerosene in a vast scale is another main reason for increasing Carbondioxide. That is responsible for green house effect. Here this image will make it clear,

d. Industrial Carbondioxide production: Different type of industries produced Carbon-dioxide and other harmful gases in a large scale. This picture mentioned it,

e. C.F.C. gas: Many man maid things like refrigerators, aerosol cans, fire extinguisher chemicals produced C.F.C. gases that are most helpful for green house effect. It is like,

f. Nuclear reactor: In modern world nuclear reactor is used in commonly is also responsible for produced carbon-dioxide in a large scale. This is happened like this,

g. Inconsiderate Urbanization: Inconsiderate urbanization is another cause of green house effect that means some one build infrastructure with out planning. Here is an example,

4. HOW THE ENVIRONMENT IS INFLUENCED BY GREEN HOUSE EFFECT? Our environment is directly influenced by green house effect. For green house effect the temperature of our world is highly increasing. Extended temperature is too much harmful for every thing which are the element of our environment. Main problems are mentioned bellow,

a. Ices are melting down: For global warming Arctic ices are melting down in a high scale. Hers is that,

b. Increasing sea level: Some low laying areas like Asia pacific, America, Mexico, Bangladesh, Some portions of India are in a great threat of going under water for melting of ice. That is really an alarming matter for us. Here is an image which mentions the infected areas,

c. Ecological Imbalance: Plants grow in suitable area and temperature so if the temperature is high then plants can’t grow and total ecological system is hampered. Here is this,

d. Human are in dangers: Health of human beings are in high mortality rate and increasing infections disease.

e. Total environment pollution: For green house effect the total environment is in a high risk all elements if environment is polluted by green house effect.

f. Animals are in high threat: All types of animals are in danger for the reason of green house effect. They lost their home & food. Some are already existed for green house effect. This pictures will make it clear,

5. WHAT SHOULD BE DONE TO SAVE OUR ENVIRONMENT FROM GREEN HOUSE EFFECT? Though the green house effect is a massive attack to our environment and that should be stopped. First we have to think, for what it is happened and that causes must be eliminate by anyhow. a. Plant more trees : We must plant more trees where we can, in town or village.

Tree plantation may be like that at urban place

b. Burning fuel in restriction: Vehicles should use protection kits to reduce Carbon-dioxide producing.

c. Set safety filter on industrial fume exit pipe: Every industry must make their exit pipe safe by taking preventive steps soon. d. Leave C.F.C: In every place where the C.F.C is used must be stopped. Our scientist should invent some alternatives of C.F.C what is not harmful for environment.

e. Responsible urbanization: For live and other needs we must built road & building but not inconsiderately. We must do that with environment friendly thinking. That may be like this,

f. Make every one environment award: Every one must be acknowledged about the environment, its important ness & what happed to it so they will try to save the environment. So by taking every type of precaution we can make our environment safe and sound thus our world will be a place for happiness and peace……..
