Study of Environmental Issues Associated with Industrialization


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


similar symptoms as humans. So if the ozone layer that we depend very much on


is destroyed, it could be concluded that we as inhabitants of the world are also


destroyed.


It is believed but not yet proven that we are altering the world climate


by releasing chemicals into the atmosphere by a process called “global warming”


or the “greenhouse effect”. Some of the chemicals that are believed to


contribute to the greenhouse effect are carbon dioxide (CO2), nitrous oxide,


halogen gases and CFCs. These chemicals cause the climate of the world to


increase by trapping the suns heat in the atmosphere and can last anywhere from


one decade to one century. Although chemicals released by man only account for


one third of the greenhouse effect, it is our contribution to this problem that


will set the world off balance. It seems now that by the year 2100, carbon


dioxide will double, causing global temperatures to rise to anywhere in between


one point five to four point five degrees Celsius. Many people may wonder why


global warming is such a problem as humans can easily adapt to their environment.


If this global warming causes global temperatures to rise, we as humans will be


able to cope with this change, however plants and animals may not be able to


adapt to this change and as a result they may die and become extinct, resulting


in a break in the food chain. The ocean levels will also continue to rise as


they have been at a pace of two to eight centimeters a decade for several more


decades. In fact, if Antarctica melts sligh

tly the ocean level can rise up to


sixty meters. As the global temperatures rise, the world will become drier and


therefore there will be more droughts, and heat waves possibly causing more


fires and again producing more CO2 and further contributing to the problem.


Ocean temperatures, currents and fish habitats will also change with the climate


of the world. Chemicals however, are not only believed to heat up the world in


the process of global warming, chemicals are also the probable cause of an


unexplained coolness in some parts of the world. Sulfur dioxide is a chemical


that reflects sunlight and because it reflects sunlight it is assumed that


sulfur dioxide cools specific areas of the earth that should be warmer.


Chemicals cause a lot of indirect damage to all living things on earth,


however, it is possible and most frequent that chemicals endanger the lives of


living things directly. Unintentionally inhaling chemicals is one way these


chemicals can harm us directly. Carbon monoxide, when inhaled, binds to the


blood’s hemoglobin and prevents the necessary oxygen from reaching tissues.


When inhaled, carbon monoxide can also dull mental acuity. A deadly chemical


cloud at ground level called smog also endangers the health of living things.


Volatile organic compounds (VOCs) and nitrogen oxides (NOx) from vehicle exhaust


and industrial emissions combine to form ozone at ground level. When the sun


reacts with this ozone layer at ground level, it produces smog. Every year the


ozone layer at ground level has increased by one percent. As carbon dioxide


emissions increase throughout the world, some plants may benefit from this


increase and so this excess carbon dioxide may act as a fertilizer, but to other


plants, too much carbon dioxide may be a bad thing, causing the plant to die and


possibly become extinct. The St. Claire River is now known as “Chemical Valley”


because of an accident that had occurred there several years ago. An industrial


company near the river had spilled sixty different chemicals mixed together into


the river. This accident had sterilized the river and had effected much of the


agriculture around it. The Great Lakes is another example of the direct effect


of chemicals on living things. There are chemicals in our body today that there


not present back in the early 90’s, the polluted Great Lakes that we locals


depend on, are believed to be the cause. Animals reproducing near the great


lakes and that rely on the great lakes are more frequently unsuccessful then


before, female birds are growing crossed bills, males are either immune to this


or die in the shell, fish are being feminized because the do not have secondary


sex steroids which chemicals from the pulp and paper industry are believed to be


responsible for. For humans, the sperm count in men has decreased fifty percent


in the last fifty years, breast cancer has become an epidemic, males experience


genetile disorders and children have problems learning.


Chemicals released into the atmosphere by industry, vehicles, fertilizer


use, etc. can harm plant, animal and even human health, so therefore if this


problem is not resolved quickly, the world we live in now could soon turn into a


world of chaos. If a species of any animal becomes extinct the food chain will


collapse, if any species of plants become extinct the food chain again will


collapse and if that species of plants is used for any type of medication, the


people who depend on that medication may also die. There are some organizations


in the world that are trying to turn things around, however there are not enough


people to support these groups. The general public doesn’t seem to care much


about this problem or is not yet aware of this issue. Even the government of


Canada doesn’t not want to take action against pollution more then likely


because of budget limitations. It was concluded by Dr. Gordon McBean that


“Humans have already radically altered the composition of the atmosphere and


hence it’s radiative properties. In other words, we have quite unintentionally


started a long-term, global-scale geophysical experiment with the life-support


system of this planet – an experiment that we do not control and, as yet, poorly


understand. That, in itself, is cause for concern.”
