Study Of Environmental Issues Associated With IndustrializationStudy 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 a
OzoneOzone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The ozone
Acid Rain LegislationAcid Rain Legislation Acid rain is a destructive force as a result of nature and man colliding. It is formed through harmful industrial emissions combining with contents of the earth's atmosphere; a dangerous combination. This prompted governments throughout North America to take action. Many laws and regulations have been implemented, yet the question still remains, Should tougher legislation be implemented to force industries to reduce acid rain emissions? To decide whether tougher legislati
