Impact Of Global Warming On Canadians

1023 words - 5 pages

Global warming is a word you hear so often but many do not know what it is. It is the result of greenhouse gases warming the Earth’s atmosphere due to the thinning of the ozone layer. Canada has a diverse environment and due to global warming, our beautiful environment is constantly being put into danger whether it is our luscious forests, the variety of ecosystems or the magnificent glaciers in the Arctic. There are three factors which are the largest contributors to greenhouse gases which result in global warming and climate change. The three causes are home energy, food and transportation. Each cause can be reduced if Canadians do the littlest things which we are not doing to the full extent. As global warming and climate change continues to be a growing problem, Canadians should be more aware about their input by closely watching the energy usage, food consumption and transportation methods.

According to scientists, an average home contributes more to global warming than the average car. If Canadians switch to compact fluorescent lights (CFL) instead of incandescent and use the heating and cooling systems more efficiently, we would emit less greenhouse gases. Firstly, studies show that if Canadians turn off one 6-watt incandescent bulb that burns for eight hours a day, they can save 1,000 pounds of carbon dioxide over the lifetime of the bulb. Each CFL bulb saves 450 pounds of carbon from being produced. Additionally, they are 75 percent more efficient than regular bulbs. If everyone switched to one CFL bulb, we would be able to prevent greenhouse gas emissions equivalent to that of more than 800,000 cars. Secondly, using the heating ventilation and air conditioning systems (HVAC) efficiently and reducing the usage can make a huge difference in greenhouse gas emissions. The U.S Department of Energy state that HVAC systems emit more than half a billion tons of carbon dioxide annually. Installing a programmable thermostat or sealing air ducts, can each reduce a regular family’s carbon dioxide emissions by five percent. Energy usage within our homes is necessary but if we take time out of our busy schedules to use the HVAC systems more effectively or change our light bulbs, we would also be helping the Earth.

Until recently, it had not been known that food also contributed to global warming. First of all, majority of the farming done now is inorganic or chemical agriculture. Through this method, pesticides and fertilizers are used. These pesticides and fertilizers often have fossil fuel ingredients in them. The fertilizers in the soil produce nitrous oxide which is a greenhouse gas that is 300 times more powerful than carbon dioxide. On the other hand, organic farms use manure and compost as the fertilizer which store the carbon in the soil and keep it out of the atmosphere. Also to manufacture and transport pesticides and fertilizers contribute significantly to greenhouse gas emissions. Secondly, a report done in 2006 by the United...
