The world is currently witnessing an ecological threat called global warming. It is mainly caused due to the overall imbalance in nature. Global warming is most commonly referred to as the rise in temperature that is occurring everywhere around us and it is drastically causing changes in the climatic conditions. Almost every organism on the earth will be affected by the abnormal weather conditions. Human beings conduct many activities that release gases such as carbon dioxide, methane, water vapor, nitrous oxide etc in excessive quantities. These gases, which are present in the atmosphere, absorb the sun's heat and radiate the same thus keeping the atmosphere warm. There are innumerable sources that contribute to this problem. Chlorofluorocarbons are extremely harmful to the ozone layer and it mainly results due to the refrigeration and air conditioning that we use in our homes. The ozone layer encompasses the earth and it regulates the atmospheric temperature by entrapping the harmful ultraviolet rays.
