Smog is the backdrop to most
industrialized economies. Factories produce large amounts of heat and release
this energy, along with harmful chemicals burned by the plants, into the atmosphere.
In most cases this is done on a daily basis, and in cities like Edmonton, a
cloud of grey industrial smoke covers the tops of buildings and industrial plants.
The release of smog is a form of pollution in the atmosphere causing higher
levels of ground-level ozone and consequent depletion of the ozone layer. As we
continue to search for more renewable resources, the smog enveloping most of
our bustling cities serve as deadly reminder to the hazards the Earth faces if
more by way of conservation efforts is not done.
