Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. In Canada, the main sulphuric acid sources are non- ferrous smelters and power generation.
In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source. When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife.
However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one.
This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. Already Ontario lakes are completely dead or dying. An additional 48 are sensitive and vulnerable to acid rain due to the surrounding concentrated acidic soils. Canada does not have as many people, power plants or automobiles as the United States, and yet acid rain there has become so severe that Canadian government officials called it the most pressing environmental issue facing the nation.
But it is important to bear in mind that acid rain is only one segment, of the widespread pollution of the atmosphere facing the world. Each year the global atmosphere is on the receiving end of 20 billion tons of carbon dioxide, million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons of nitrogen oxides, more than three million tons of arsenic, cadmium, lead, mercury, nickel, zinc and other toxic metals, and a host of synthetic organic compounds ranging from polychlorinated biphenyls PCBs to toxaphene and other pesticides, a number of which may be capable of causing cancer, birth defects, or genetic imbalances.
A wide range of interactions can occur many unknown with toxic metals. In Canada, Ontario alone has lost the fish in an estimated lakes and provincial authorities calculate that Ontario stands to lose the fish in 48 more lakes within the next twenty years if acid rain continues at the present rate. It can scar the leaves of hardwood forest, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to a state that is vulnerable to disease infestation and decay.
In the soil the acid neutralizes chemicals vital for growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil. Acid rain no longer falls exclusively on the lakes, forest, and thin soils of the Northeast it now covers half the continent.
EFFECTS There is evidence that the rain is destroying the productivity of the once rich soils themselves, like an overdose of chemical fertilizer or a gigantic drenching of vinegar. The damage of such overdosing may not be repairable or reversible. On some croplands, tomatoes grow to only half their full weight, and the leaves of radishes wither. Naturally it rains on cities too, eating away stone monuments and concrete structures, and corroding the pipes which channel the water away to the lakes and the cycle is repeated.
Paints and automobile paints have its life reduce due to the pollution in the atmosphere speeding up the corrosion process. In some communities the drinking water is laced with toxic metals freed from metal pipes by the acidity. As if urban skies were not already grey enough, typical visibility has declined from 10 to 4 miles, along the Eastern seaboard, as acid rain turns into smogs. Also, now there are indicators that the components of acid rain are a health risk, linked to human respiratory disease.
PREVENTION However, the acidification of water supplies could result in increased concentrations of metals in plumbing such as lead, copper and zinc which could result in adverse health effects. After any period of non-use, water taps at summer cottages or ski chalets they should run the taps for at least 60 seconds to flush any excess debris.
Presently, the United States annually discharges more than 26 million tons of suffer dioxide into the atmosphere. Just three states, Ohio, Indiana, and Illinois are responsible for nearly a quarter of this total. Overall, two-thirds of the suffer dioxide into the atmosphere over the United States comes from coal-fired and oil fired plants.
The outlook for future emissions of suffer dioxide is not a bright one. Between now and the year , United States utilities are expected to double the amount of coal they burn.
The United States currently pumps some 23 million tons of nitrogen oxides into the atmosphere in the course of the year. What makes these figures particularly distributing is that nitrogen oxide emissions have tripled in the last thirty years.
