The greenhouse effect is an effect on the atmosphere as a result of the presence of a certain gases called greenhouse gases which are made up of carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, low-level ozone and water vapour. Greenhouse gases in the atmosphere are similar to the greenhouse glass panes which trap the heat and warm the greenhouse.

When the greenhouse effect occurs, sunlight enters the Earth’s atmosphere and while some solar radiation is reflected back to space, most of the radiation is absorbed by the Earth. As the Earth is warmed, heat in the form of infrared radiation is radiated back into the space. However, much of this does not escape from the atmosphere but remains trapped by the greenhouse gases, warming the atmosphere and cause the infrared rays to be radiated back towards the surface of the Earth.

The causes of greenhouse effect include deforestation. Our population is increasing and to accommodate to needs for amenities and economic stability, more and more forests are being cut down or burnt. This in turn heightens the percentage of carbon dioxide as there are not enough plants to absorb carbon dioxide for photosynthesis. To overcome this problem, the authority has to implement regulations to address this issue by constraining the law and penalising those who do not comply with the law.

Besides, the burning of fossil fuels like petroleum has greatly raised the levels of carbon dioxide. For this, alternative sources of energy such as geothermal energy, biomass energy and wind energy should be utilised so that the environment is not affected by this combustion activity.

Moreover, electrical appliances are a contributor to this issue too. Electrical appliances like refrigerator and air conditioner releases chlorofluorocarbons which have added to the greenhouse effects. Therefore, hydrofluorocarbons (HCFs) should substitute CFCs as these gases break down in the atmosphere and return to the Earth...
