We begin by examining the effects of natural resource development upon one of the most critical components of watershed systems altogether, the water itself. Water is essential for all living organisms, and it is highly valued by Canadians. In a 2009 Nanos research poll, it was found that 61.6 percent of Canadians believe that retaining the integrity of Canadian freshwater supply is the most important natural resource issue that this country will face in the future. As industrial disturbances increase throughout Canada’s northern forests, the risk of potential damage is increasing within affected watersheds. Alteration, typically induced by increased inputs of nutrients, sediments, and contaminants, can have significant negative impacts upon …show more content…
The industrial activities of both require the removal of forest vegetation in order to explore or gain access to extraction sites. The proximity of cut blocks, well-sites, or mines to hydrologic systems will determine the magnitude of the impact. After a significant disturbance event, such as large scale removal of vegetation from a landscape, the ability of the landscape to resist erosion is severely reduced. As a result, large amounts of sediments and nutrients that were previously held and utilized by the natural vegetation communities present enter the local hydrological system. After a disturbance event, typically large flushes of nitrogen, phosphorus, and potassium are observed entering local hydrologic systems (Richardson, 2008 and Webster et al., 2014). Alongside this nutrient flush, greater sediment deposition also occurs. This increased sediment load has a significant effect upon stream turbidity, reducing stream clarity and the ability of light to penetrate to lower depths. With the increase in stream turbidity, an increase in temperature of the hydrologic system can be observed. The darker colouration of the stream, as a result of the deposition, results in increased absorption of solar
The Hudson plains are in parts of Ontario and Manitoba. Their area is about 350 000 km squared. The west edge of the Hudson Plains is around Churchill in north Manitoba, the eastern edge is around Fort Rupert, the northern edge borders Hudson Bay and James Bay and the southern edge is near Kapuskasing, Manitoba. Moosonee and Churchill are major cities in the Hudson Plains area, and lesser known cities include Attawapiskat, Fort George, Eastmain, Fort Albany, Lake River, Winisk, Fort Severn, and Shamattawa.
Mountain Top Removal is an American tragedy, the process in which mining companies remove forests and topsoil then explode the mountain apart level by level to get to coal layer. It is estimated that the explosives are equivalent of the Hiroshima bomb. A lot of the mining waste is discarded into valleys and streams; the water runoff is high in silt, ion, and sulfur compounds, which in turn pollute water downstream. Even with chemical treatments, vegetation has a hard time growing on the infertile and highly acidic soil. Mountain top removal occurs in eastern Kentucky, southern West Virginia, southwest Virginia, and east Tennessee. Virtually 1.2 million acres of land has been surface mined and more than 500 mountains have been ruined by mountaintop removal mining.
Currently, over half of the world’s population lives in urban based areas (Owrangi et al, 2014), and this increase in population is expected to contribute to further increases in flood risks (ibid). Vancouver has achieved rapid socioeconomic development due to the increased employment opportunities and growth rates, directly stressing local natural resources by increasing population and urbanization (Owrangi et al, 2014).
The industrialization of Canada is severely affecting the nations lakes, streams, and rivers. If something is not done to improve the situation it is going to have some severe environmental problems in its future. The following essay will be looking at the factors that cause pollution, and the effect that pollution has on the environment of Canada. It will also explore some of the methods used to treat and clean-up wastewater, and oil spills.
Chapter 1: Regions of Canada describe regionalism and how it divides countries, specifically Canada, naturally into six regions: British Columbia, Western Canada, Territorial North, Ontario, Quebec, and Atlantic Canada. These regions have been divided in a manner that correlates ‘like spaces’ in regards to human and physical geography (Bone, p.6) along with Canada’s historical development. The second key feature of chapter 1 describes Canada’s faultlines and they’re affects on Canada’s regional divide. There are four faultlines within Canada that reciprocate tensions that are mostly solved by being “soft” through negotiation and discussion (according to John Ralston Saul, Bone, p. 10). Bone places a great focus on these faultlines, which include: centralist/decentralist, Aboriginal/Non-Aboriginal, French/English Canadians, and newcomer/old-timer. “Canada’s heterogeneous nature often forms the basis of regional quarrels” (Bone, p. 11) particularly for the centralist/decentralist faultline. English/French speaking Canadians focus on Quebec and sovereignty, while the Aboriginal/Non-Aboriginal faultline deals with land claims, settlement and colonized peoples. Newcomers/old-timers refer to immigrants and settlers of Canada. The core/periphery model is a key concept that is commonly referred to throughout the text. It depicts the core as concentrations of power/wealth/population, with the periphery/hinterland as the weakly developed, resource based area.
As global temperatures and ocean levels rise, the water levels of the Great Lakes continues to fall. As the lakes hit their all time lowest level in global history in 2012, society remains ignorant to the imposing doom that lurks ahead. Since the Great Lakes make up the largest group of fresh water lakes on Earth and are responsible for approximately 21% of the Earth’s fresh water supply, this issue is becoming one of the largest environmental and economical issues our modern world faces. The effects of this issue include destroying animal habitats and a major economic market; shipping. Water levels in the Great Lakes have been dropping for the past fourteen years, but it wasn’t until boats were scraping the bottom of Lake Huron that people began to take notice. This terrible environmental issue has been dubbed a long term cycle of over evaporation and not enough precipitation to replenish the Lakes. Keith Kompoltowicz, chief of watershed hydrology for the United States Army Corps of Engineers in Detroit has been monitoring this issue for a decade and has made startling discoveries, such as in 2012, he discovered Lake Michigan and Lake Huron’s water levels only rose four inches after winter, whereas the Lakes have been regularly recorded as gaining a foot of water after the winter season had ended. This amount of water added is not enough to maintain a proper water level during the dry, hot summer seasons that evaporate much water from the Great Lakes. While some scientists say that this is just a cycle that will adjust itself naturally, most experts that have been studying this phenomenon, such as Kompoltwicz, would agree that the issue has gone to far
Because of farm fertilizer, an excess quantity of nitrogen and phosphorus can be wash down becoming runoff into rivers. From this, marine algal blooms cause the water to turn green from the chlorophyll (Reed, 2011). Eutrophication then becomes a dilemma in the system causing either an increase of primary production or an expansion of algae. An enormous expansion of phytoplankton on the water’s surface is then established. At the same time the water column is also stratified, meaning things such as the temperature and salinity are not sync from top to bottom. The seasonal warm surface water has a low density forming a saltier layer above while the cooler and more dense water masses near the bottom layer is isolated from the top cutting off oxygen supply from the atmosphere (Overview, 2008).
One of the most visible and mutual environmental impacts of ski areas on the environment is deforestation and grading of slopes. In order to service a multitude of winter sport enthusiast, mountain slopes must be cleared of dense forest in order to make way for ski runs and lifts. With the ski industry in the US showing steady numbers (Satistica) resorts have to come up with new attractions to keep past patrons and attract new customers. One of the ways that they do this is by opening up new terrain, which increases the amount of deforestation damaging the local vegetation. Ski resorts essentially have two options in creating new terrain. First clearing runs by removing trees and other woody vegetation, leaving the topsoil and seed bank intact or by grading slopes by using bulldozers to remove any abnormalities. The second method is preferred as it is faster and more efficient and allows for the slope to be opened earlier with less snow pact.(USA) The impacts of grading slopes by bulldozing destroy the vegetation, reduce the topsoil and greatly contribute to erosion. The removal of woody vegetation can also lead to a drastic change in the local vegetation in order to keep the trails clear it requires constant trimming of the new growth of unwanted vegetation that can help anchor topsoil in place and provide better growing conditions for other plants. The destructive method of bulldozing runs not only leads to environmental degradation but also can be counter productive. According to a UC Davis study, while clearing slopes of vegetation and irregularities by bulldozer might result in opening earlier than other resorts the increase in maintenance, will likely offset any monetary gains (USA).
'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling
...tario. The great lakes Water Quality Agreement is an international agreement between Canada and the United States their collective goals are to restore and maintain the Great Lakes. The agreement outlines the commitments of both countries to restore and maintain water quality and aquatic ecosystem health in the Great Lakes. Since 1989 Canada has spent 355 million dollars to help restore the ecosystems. Canada currently invests 48 million a year on the restoration projects. President Barack Obama's administration developed the Great Lakes Restoration Initiative in 2009, that provided $475 million dollars the first year and $300 million annually since. Last year a house subcommittee proposed slashing the allocation to 60 million starting in 2014. It is feared that this 80% cut would gut the programs and this would have a major impact on Canada and the U.S. Sources
Blue, incredibly clear, and seemingly pure, just twenty years ago it abounded in fish. But now, this exquisite lake is dead, it’s fish wiped out.” Moreover, another developmental device used in the essay “Acid Rain: Scourge from the Skies” was comparison and contrast to show the difference between the amount of polluting oxides that Canada puts into the air each year compared to the

The Great Lakes provide almost half the water for the residents of Ontario. The Great Lakes also provides water to residents in Thunder Bay, Port Hope, Sault St Marie, Niagara and many parts of The United States to name a few. With 70% of the Earth covered in water only 0.1% of it is clean accessible drinking water. The Great Lakes plays a major role in helping to provide water for people that live near the American/Canadian border. However this resource is being mistreated. Water pollution is a growing problem in the Great Lakes. The Great Lakes is being contaminated by pollutants that are released for direct and indirect sources without proper treatment. This is causing the lake to being polluted with harmful chemicals. By identifying the cause we can take initiative to help conserve the Great Lakes and to help restore it to its natural beauty.
As a result of this process, the mine sites "do not develop normal soil structure or support the establishment of a plant cover". Many mine sites have...
