How have the US and Canada worked together to solve the problem of acid rain?
After years of prodding and lobbying, the US updated its Clean Air Act in 1990. It was followed by the Canada-US Air Quality Agreement signed by Mulroney and Bush in Ottawa in 1991. The agreement aimed to reduce pollution on both sides of the border that caused acid rain. And it worked.
What has the US done to reduce the acid rain problem?
Because nitrogen oxides are formed in the process of burning coal and other fossil fuels, some power plants are changing the way they burn coal. A good way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.
What are some of the solutions Canada is trying to use to solve acid rain in Canada?
The main elements of the strategy are:
- reducing sulfur dioxide emissions in eastern Canada and the United States.
- protect clean areas from degradation.
- maintain science and monitoring programs and.
- report regularly to ministers and the public.
How did the acid rain program reduce acid rain in the US?
The objective of the ARP was to reduce the deposition of acid rain by reducing sulfur dioxide (SO2) emissions from power plants to 50 percent below 1980 levels by 2010. To achieve this goal, regulators set a cap on the annual total SO2 emissions from central and midwestern power plants and created a market for trading allowances.
Which part of Canada is most affected by acid rain?
Provinces that are part of the Canadian Precambrian Shield, such as Ontario, Quebec, New Brunswick and Nova Scotia, are most affected.
What is the best solution to the problem of increasing acid deposition?
The best solution to the problem of increasing acid deposition is a combination of approaches. Technical fixes, such as clean coal technology and catalytic converters on cars, may help reduce some of the man-made emissions.
What are the main causes of acid rain in Canada?
Acid deposition occurs when sulfur dioxide and nitrogen oxide emissions are converted into secondary pollutants. Examples of such pollutants are sulfuric acid, ammonium nitrate and nitric acid. These pollutants then fall onto land, water, vegetation or structures.
What problems are caused by acid rain in Canada?
The ongoing industrialization of society has resulted in increased release of acidic chemicals into the atmosphere. Acid rain has wiped out fish, molluscs and frogs in thousands of eastern Canada's lakes. Acid rain has wiped out fish, molluscs and frogs in thousands of eastern Canadian lakes (photo by Don E.
Acid rain occurs when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These are then mixed with water and other materials before falling to the ground.
Canada's response. The result was the Canada-Wide Acid Rain Strategy for Post-2000, published by Environment Canada in 1998, to help protect acid-sensitive areas and human health in Canada. It lays out a framework for solving the acid rain problem in eastern Canada and preventing one in western and northern Canada.
How is the US helping to reduce acid rain?
Fulfilling the commitment to further reduce SO2 emissions, Ontario, Quebec, New Brunswick and Nova Scotia announced a further halving of their provincial sulfur dioxide targets by 2010 to 2015. For its part, the US is considering significant further sulfur and nitrogen oxide reductions over the next 10 to 15 years.
How are the US and Canada improving air quality?
Both Canada and the United States have made significant progress in reducing emissions of pollutants that cause acid rain and ground-level ozone since 1991. As of 2017, emissions of sulfur dioxide in Canada and the United States have decreased by 69% and 88%, respectively. from 1990 emission levels; and,
What did the US and Canada agree to do?
Both countries agreed to reduce emissions of sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ), the primary precursors of acid rain, and to work together on acid rain-related scientific and technical cooperation.
Anyone who remembers the 70s and 80s will probably remember acid rain. Industrial emissions acidified precipitation around the globe, which killed forests an…
