Pollution in Ontario


When many of us think about the province of Ontario, in terms of the environment,
pollution comes to mind. Pollution is the process in which the land, air and water become polluted due to poisonous chemicals. Air pollution is the release of chemicals into the atmosphere. Mostly from carbon monoxide and other gases produces my cars, and factories. “About half of the air pollution in Ontario comes from the U.S. due to air flows.”(Government of Ontario, 2007). Climate change can affect the pollution thus making this harmful smog even worse, because some photochemical smog and ozone are created as harmful hydrocarbons because of the reaction to sunlight. “Smog can form in almost any climate where industries or cities release large amounts of air pollution. However, it is worse during periods of warmer, sunnier weather”(Government of Ontario, 2007). So changes in climate, like increase sunlight, can therefore affect pollution. Thermal pollution is when natural water bodies undergo a change in temperature. This change in temperature is influenced by humans when they see water as a coolant in a power plant. “The effects of this increase in water temperature can have an impact on aquatic organisms by (a) decreasing oxygen supply, (b) killing fish juveniles which are vulnerable to small increases in temperature, and (c) affecting ecosystem composition”(Government of Ontario, 2007). Although a lot of air pollution is invisible, some types can be seen by the naked eye as the smoke released from smoke stacks.
Mostly smog is caused by air pollution and greenhouse gases, and therefore, climate change, land and water is contaminated when pollutants fall in rain or snow. Since most of our affects on weather patterns is due to global warming, we call this climate change. “Global warming is caused by the dramatic increase in greenhouse gases in our atmosphere”. (Government of Ontario, 2007). This is where we can see the link between Global Warming and Climate Change, especially in Ontario since Pollution is very prominent in this region.
