Greenhouse Effect Essay- Essay for all class
In the modern world energy and wealth are being used so excessively and for so many purposes that day by day the balance between various forces and elements of nature is being disrupted. Consequently, everything in nature is running towards an inevitable side-effect called the Green House Effect.
In the polar regions one kind of house is made of glass for growing crops in it. When the rays of the sun fall on earth their wave-length is so small that they fall on the soil inside the house without heating the glass-walls. When those rays are reflected by the earth, their wave-length gets larger and thus they can easily heat the glass-walls. This process of artificially heating up the glass-houses is called the green house effect. Though it is fundamentally the name of a scientific process, now we refer by it to a dangerous effect being caused in the atmosphere.
For various scientific reasons, nowadays the amount of carbon-di-oxide, mithen, nitrous oxide, cloroforo carbon are increasing the atmosphere. Consequently, when the rays of the sun, after being reflected by the earth, goes up with larger wavelengths, the above-mentioned gases get heated by it like the glass wall of the aforesaid greenhouses.
The result is obvious and fatal: the temperature of the atmosphere around the earth. increases more than normal. In this process, as the amount of those gases are increasing in the atmosphere, the temperature of the atmosphere over the earth is increasing day by day.
It is anticipated by scientists that by the year 2050; the amount of these gases will double and this phenomenon will be followed by an increase in the temperature by 1.05??C 4.50??C. And in the next fifty years,??such increases in the atmosphere will bring about an unimaginable change in this planet of ours.
This effect will tell upon the earth in a dangerous way. By the middle of the next century, as a result of the increase in the temperature of the atmosphere, ices in the polar regions will begin to thaw and will come down on to the seas. As an inevitable result, the water level will go higher. Many low areas of the earth will go underwater. Moreover, rainfall and the intensity of storms will increase dramatically. Then life will be very hard on earth.
The low-land countries like Bangladesh will have to suffer the most. As far as our country is concerned, if the water-level goes one meter higher, then about 16% of the land of this country will go under wate. As a result, about fifty 'thanas' of thirteen districts will be damaged. The existence of about 14% of the cultivable land and 28% of the forest will be destroyed.
The fate of about one crore people will be doomed to uncertainty. What is more, according to surveys made by the scientists, we will suffer an aggregate loss of about 20 lakh tonnes of rice, 13 thousand tonnes of wheat, 2 lakh and 14 thousand tonnes of sugarcane, and 4 lakh tonnes of vegetables. Moreover, there will be serious damages to houses, communications, and cattle.
As an inevitable consequence of the Green House effect, there will be a great change in the climate. The number and intensity of natural calamities will increase: drought, flood, cyclones, and tidal bores will threaten the existence of life. is ones?
But we can take the necessary steps not to let all these things happen in the near future. As the first measure, the emission of the Green House Gases is to be stopped. These gases are to be transformed into some other substances so as not to let them mix with the atmosphere.
Forests are to be saved from destruction. Moreover, we must take the necessary??steps to increase the number of forests in the country. The people of the country are to be made aware of the consequences of the increase in the amount of Green House Gases in the atmosphere.
Many other countries will suffer damage like Bangladesh. So, as a preventive measure, the governments of these countries may put combined efforts to take necessary initiatives. The UNO should also come forward to make the whole world conscious about the dangers of the Green House Effect.
In conclusion, it can be said that we can save the earth, and we should. For this,??all the countries, as well as the general people thereof, should be on the alert. And our determination should be to save this planet at any cost.
