Greenhouse reactions are one of the negative characteristics of nature. For various man-made reasons, the greenhouse effect has created a great crisis in our country. The various gaseous conditions in nature are responsible for causing the greenhouse effect.
The sun is not seen for a long time of the year in the extreme cold regions of the polar regions of the world. At this time there was an acute shortage of green vegetables. In this context, scientists invented a special type of glass house. The roof and walls of this house are made of special type of glass that resists heat radiation. In summer, sunlight and heat enter the house, but it cannot go away in response to radiation. It is possible to produce vegetables by using the stored sun heat. Scientists have named such a scientific house 'Greenhouse' in winter country.
The word greenhouse literally means 'green house' but now it is widely used as a 'glass house'. Think of a house whose walls and roof are made of glass. As a result, it can easily enter the ala. But even if it can enter Ala easily, it cannot come out according to Ala's refraction formula. As a result, the temperature of the glass room increases. Needless to say, this temperature exceeds the outside height. This abnormal condition is called the ‘greenhouse effect’. According to this glass house of the earth, the atmosphere has 30 km from the surface. As far as ozone is concerned, however, the concentration of this layer is not the same everywhere. 23 km Above this the density is relatively low or weak. This layer contains carbon dioxide and a few other gases. These gases are called 'greenhouse gases'. This is because the way the walls of the glass house retain their inner temperature without being radiated, this gas enclosure or screen prevents radiation from the surface heat. As a result, global warming is normal, and the earth is home to animals and plants.
As of November 2009, the Protocol has been ratified by 17 countries (including the European Union). The protocol was not ratified by Kazakhstan and the United States. Although China and India play significant roles in greenhouse gas emissions, the level of EU emissions does not apply to them. The list of selected countries in the world emitting greenhouse gases is shown in the table.Environmental International Agency)
Scientists are worried about the dangers of the ‘greenhouse effect’ in the world to come. They identified excessive population growth and unplanned activity as the cause of the potential catastrophe. Unplanned urbanization is going on to meet the needs of the large population, mills and factories are being set up everywhere, and transportation is on the rise. Different types of engine driven vehicles. Forests and vegetation are being cleared for settlement and industry. As a result, the amount of oxygen in the air decreases and carbon dioxide increases, creating a very harmful gas called 'chlorofluorocarbon' in the atmosphere. This gas destroys the ozone layer, which produces ultraviolet rays produced by the greenhouse effect. Vehicle smoke, toxic industrial wastes and fumes are also causing severe damage to the ozone layer. More food is needed to feed the extra population. And the use of fertilizers and pesticides on crops is increasing every moment to produce more food. Scientists are destroying the normality of the ozone layer by exploding hydrogen bombs and causing nuclear explosions, intoxicated with the deadly game of making lethal weapons. In a word, people themselves are constantly calling for their own defeat today.
As a result of the greenhouse effect, the surface temperature and the resulting gas increase. As a result, the ozone layer in the atmosphere is inevitably being severely damaged. Outbreaks appear to be exacerbated during exposure to the sun's harmful ultraviolet rays. Natural disasters such as storms, floods, tidal floods, etc. have occurred due to the rising sea water due to the melting of frozen ice in the polar region. Geologists and meteorologists fear that there will be catastrophic changes in the surface and atmosphere at the end of the present century. Panic over submergence of towns, cities and ports has now become a strong greenhouse effect in the global environment; Scientists are now worried about the global environment, in some cases panicked. There is a lot of research going on in tropical countries. Professor at the University of Marburg in West Germany. Jenner Heber's study found that the effects of harmful ultraviolet rays have already exceeded 5%. As a result, the phytoplankton of the ice country Antarctica is being severely damaged. If this process continues, all life in the Southern Hemisphere will be exhausted. According to a report by the Japanese Environment Agency, global warming will increase by 1.5 degrees Celsius to 3.5 degrees Celsius by 2030.
Scientists think; As a result, the sea level will rise by one and a half meters as glaciers and ice melt. About half of the world's population, including SAARC countries. Researchers fear that this could lead to flooding.
Most of the fears that scientists have raised apply to Bangladesh. Due to its location in the tropics, the warming of Bangladesh continues and deforestation is taking place. As a result, the normality of the atmosphere is being destroyed, the temperature is rising. Even all the southern parts of the country are likely to be submerged; And the effects of salinity and desertification are being felt right now.
Possible remedies for the greenhouse effect: To save mankind from the greenhouse effect, remedial action must be taken now. Such as:
1. Deforestation must be stopped.
2. Appropriate arrangements have to be made for the disposal of these wastes by setting up industrial factories in a planned manner.
3. Arrangements should be made to reduce the smoke in the vehicle.
4, to avoid floods and inundation to build the necessary dams .
5. Care should be taken to prevent saline water from entering the reservoirs or rivers.
In order to increase public awareness, there should be a massive campaign in the media about the deadly evils of the greenhouse effect. At all levels of education, from the lowest to the highest level, greenhouse related articles should be included in the curriculum.
‘The greenhouse effect is terribly harmful to the human race. And the fear of this loss, the possibility is more applicable for Bangladesh. It is therefore imperative that concerted efforts be made to take the necessary remedial action against the greenhouse effect.
Really nice article
