Study of Environmental Issues Associated with Industrialization   Ã‚  Ã‚  Ã‚  Ã‚  Although our industrial ways seem to be a very progressive step into the future, there are many flaws to the way many things are today. Things have definitely changed over the past century, as we can currently do things much more efficiently then before. The cost of this efficiency may seem inexpensive in many ways, however we do not realize that the cost of these new technologies do not just include money, time and labour, but it also costs us our well being as well as the beauty and comfort of our own home, earth. Ozone depletion, climate change as well as the direct effects of chemicals from industrial emissions and fuel combustion are a great threat to our planet and if nothing is done to resolve this problem soon, the results may be disastrous. There is a layer of chemicals twenty kilometers up in the stratosphere called the ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial halocarbons that break up into chlorine and bromine in the upper stratosphere when they react with the sun's rays. Chlorine eats up the ozone layer while bromine acts as a catalyst and speeds up the process. Often found in Antarctica, there are frozen chemical clouds in the upper stratosphere called polar stratospheric clouds. These polar stratospheric clouds destroy the ozone layer at a much faster pace then the industrial halocarbons. The depletion of the ozone layer is a great threat to mankind and all other living things on earth because without this layer of chemicals, we will be exposed to excess UV rays. This excess exposure can lead to many things such as malignant melanoma and non-melanoma skin cancer, damage to eyes by means such as snow blindness and cataracts, which is the clouding of the eye that can eventually lead to blindness. Above all this, excessive UV exposure can lead to symptoms similar to AIDS as prolonged exposure could weaken the human immune system. As far as plants and animals go, plants may die or may not be as healthy as a result of too much UV exposure and animals will suffer
