I’ll talk about air pollution today. Canadians believe that air pollution is their biggest environmental health issue. The main sources of air pollution include gas output from burning fossil fuel, chemical, and biological contaminations of the air, agricultural pollutions, and smoking, pets’ and natural pollutions.
First, when fossil fuels such as coal, oil, gasoline, and natural gas are burned as energy to heat our homes and buildings, to power our machines, to generate electricity, and to run our vehicles, they produce many different types of gases that pollute the air, for instance, Carbon Monoxide. Have you ever heard of the concerns related to “Acid Rain”? You just may be the one to blame.
Secondly, while we’re working in biology, biochemistry, or chemistry laboratories, in industries, or in hospitals, we may contaminate our air unconsciously. Bacteria, viruses, radioisotopes, and toxic chemicals can be unintentionally released into the surrounding environment. This leads to contamination of our air source.
Furthermore, a variety of farming materials can also pollute the air. Pesticides and their residues can seep into air that we intake. Consequently, they may damage our health, which depends on what they are and how they interact with our bodies. Some fertilizer can also contribute to pollution to such an extent that is an important instigator of global warming. I don’t know whether or not you’ve paid attention to this matter. It’s said that during the peak of the pollen season each year, Environment Canada receives numerous calls from citizens concerned about the yellow dust. This yellow dust is in fact from plants. It consists of tiny grains that carry the male genetic material during pollination. It influences Asthma and causes some allergies. Agriculture is one of the biggest areas of the world’s economical output; however, it’s one of the biggest sources of pollutions too.
Finally, source of pollution other than what I’ve mentioned above include smoking, pets’ urine and fecal mater. Every now and then, nature itself can create pollution. Earthquake, hurricane, and volcano can bring about air pollutions by releasing a large amount of dust particles into the atmosphere.
The consequence of the continued escalation of air pollution is dire. Various species of fish in Lake Ontario suffer from tumours; some have almost vanished. Thus, our task as citizens of the world is to create a healthy environment for ourselves and for our offspring. A key issue on the Canadian government’s agenda is to improve air quality through the implementation of policies. The government is aware that we must make both long-term and short-term plans in the attempt to improve air quality. We must also “think globally, while acting locally” in solving the air pollution problem. It is certain that air pollution will not be eliminated in one day; however, I believe that with unified effort, we can work towards cleaner air and a healthier tomorrow.
