The Effects Of Global Warming on the Enviornment

A Closer Look at the Ozone Hole and Global warming

Introduction

The last quarter of the 21st century has offered mankind several surprises in terms of inventions and discoveries . Consequently , these inventions have made man discover more about his environment that he lives in . These discoveries varied from being a boon to a bane to mankind . One of the most dreaded discoveries of the last centuries was the discovery of the hole in the ozone layer due to the global warming currently prevalent in our world today

Mankind must heed the

warnings of Mother Nature . Early Warning signs reveal that the global nurture of climate changes . People have all pointed out the fact that there is an increasing body of observations in the warming world that needs to be addressed . It is North America and Europe t\where there is a density of indicators and where the early impacts of global warming are becoming more seen

More commonly , the ozone is known as the layer that protects human beings and other living things from the harmful rays of the sun , more specifically , the ultraviolet rays-shielding us from being stricken by skin cancer . This common conception of the ozone layer , which provides a good notion of what ozone is , is just one side of the coin . Scientists refer to this more commonly know ozone as the stratospheric ozone (Centre for Atmospheric Science . On the other side of the coin is the tropospheric or the ground level ozone , which is considered as a major health hazard , is a major constituent of photochemical smog (Centre for Atmospheric Science . It is referred to as a pollutant because of its being lethal if inhaled (Newman

How the Ozone Hole Started : A Narration of Facts

According to the National Resources Defense Council (NRDC , the story of the ozone hole has its roots from the chlorofluorocarbons or CFC 's , a family of most commonly used industrial compounds . CFC 's was invented by Thomas Midgley in 1928 which later on was called as a miracle compound ' due to its proven useful for man 's convenience (NRDC . Since then , it was effectively used in refrigeration systems , air conditioners , aerosols , solvents and in the production of some types of packaging (Francois . However , decades after the miracle compound was invented and used in many industries and households as effective refrigerants , it was found out that it had caused a serious damage to the environment , more particularly to the ozone layer . It took American scientists Mario Molina and Sherwood Rowland to prove that the miracle compound ' turned out to be damaging to the environment as they hypothesized in 1974 that CFC 's possibly played an active role in the depletion of the ozone layer (NRDC . This announcement had sparked heated debates not just among scientists but also among policymakers environmentalists and industry players on the whys and wherefores of ozone depletion (NRDC

It was explained by Newman that CFC 's became harmful to the ozone because of its chlorine make-up and it turn[ed]...
