Global Warming : Threat to humanity
Global warming is a huge problem for human on earth. We, human have been causing this catastrophe for about a century. Burning fossil fuels, deforesting are the two main human made causes that boosted up global warming at an alarming rate. As a result the earths temperature is rising, icebergs in polar regions are melting. Those caused our climate to turn into a more aggressive form that we ever witness. Rainfall has decreased, cyclones, typhoons has become more destructive in recent years. See level is rising, a large number of people living in coastal areas in different part of the earth are about to lose their home. Green house gases not just increased atmospheric temperature, it also destroyed the Ozone layer. Ozone layer is that part of atmosphere which prevents most of the Ultra Violet rays from our sun and also some other cosmic rays from reaching the earth surface. As ozone layer is compromised more UV is reaching earth surface and causing noticeable harm in animals and plants.
