Global Warming as a Global Environmental Concern Essay

INTRODUCTION As a global environmental issue of concern, controversies have been presented for and against global warming. Such controversies have stemmed from its causes as well as effects. This is because since the first international awareness of the problem that took place in 1992 during a United Nations (UN) Earth Summit in Rio de Janeiro, several opinions have continued to grow concerning the genesis of this problem as well as the potential effects posed on the planet. Such international meeting saw an intellectual exchange among the many delegates concerning the best approaches that can be used in dealing with the causes and effects of global warming. However, this problem is still a controversial one among many environmentalists†¦show more content†¦Burning of fossil fuels contributes to the addition of the greenhouse gases in the atmosphere in the sense that such fuels produces anthropogenic gases such as CFCs, methane and nitrous oxide which are responsible for the global warming. In addition, deforestation, explosive population growth, technological advancement, growing urbanization, and industrial expansion are some of the factors that account for the increases in these gases in the atmosphere. However, it is projected that the rate of the rise will continued if this global issue of concern is not nipped in the bud. Among other major causes, deforestation is argued to be the main causes of the increases in the global warming (Liss, 2012). This is because trees play a major role in the global carbon cycle since they are considered as one of the largest land-based carbon mechanism that helps in the removal of excessive carbon dioxide from the air. Due to this, deforestation has been considered as the second principle cause of atmospheric carbon dioxide contributing for 25 per cent of all the carbon emissions in the atmosphere especially through burning and cutting of trees. For instance, estimates are that over 5500 acres of rainforest are destroyed daily leading to a rise in the global carbon dioxide level which is approximated to be 0.4 per cent each year.
