Montreal plans to shut down a pipe, which feeds water from the sewers into a treatment plant. Therefore the city’s strategy is to dump the eight billion liters of raw sewage into the St Lawrence River [1]. The procedure is going against the fisheries act, it will have negative consequences for communities downstream, and it will also damage the river’s ecosystem. In brief that scheme has several negative impacts on the river’s ecosystem and the city should invest in alternative procedures.
The procedure of dumping mass amounts of wastewater into the river is going against the fisheries act if not given authorization [3]. Environment Canada is researching the implications of the plan and exploring options to prevent this release, while studying

Dr. Grant Brow who is a Concordia University biologist that specializes in aquatic behavioral and chemical ecology, claims, “The untreated effluent could cause harm to a number of aquatic species”[2]. The fish rely on chemical cues to help it survive, such as finding food, shelter, detecting and avoiding predators. On the other hand, the city’s spokesman Philippe Sabourin, says that “the contamination is not a big concern due to the sheer size of the river and how quickly it flows – at a rate of 6,000 to 7,000 cubic meters a second, compared to the flow rate of the wastewater, expected to be 13 cubic meters a second” [2]. However, it would be devastating if the city proceeds with their plan since the chemical and bacteriological mixture of wastewater must be observed at all times to ensure public health. In wastewater there are oxygen-consuming materials, which needs to be minimized to protect from low dissolved oxygen conditions since it can be harmful to aquatic species [4]. Many nutrients found in wastewater, such as nitrogen and phosphorus must be removed to prevent high level of nutrients, which can cause the ecosystem to have hypoxia and the increase of pollutants in the waterways [4]. The city has examined alternative methods, and the mayor claims that, “They have consulted with experts around the world and that every option has been explored” [5]. The city has probe to put in mobile tanks or installing a $1-billion diversion system to collect the raw sewage and send it to the treatment plant, which would be safer and more ethical
The article Victoria’s ugly stain is about the sewage treatment in Victoria. Over the past few years, Victoria population has placed over 34 billion litres of sewage into lakes and oceans. At this moment, it’s not effecting environment, but it can hazardous to environment in future years. It can also become dangerous for living beings such as aquatic life and animals in forests. For example, writer talks about the metals found in the human waste such as copper, mercury and lead are contaminating ocean water. Also toxic byproducts from motor oil and vehicle
More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.
Water is just more than drinking water. Water is the most basic and vital resource that humans need to sustain themselves. Water is used for food production from irrigating crops to actually manufacturing them. Canada like the world, uses water for sanitation, cleaning, manufacturing and daily function. Demand and supply will soon be at a crossroad, as increasing population creates increases in pollution, waste-water and global warming (Baker, 2007). This paper will seek to examine the effects of global warming on Canada’s freshwater system, the effects of pollution and will evaluate how Canada manages its freshwater now and what Canada can do to form policies that will adapt to the future crisis in Canada’s freshwater.
Companies have the technology and the knowledge to divert or sell water in a way that is safe on the environment. Part of the Canadian population has been misled to believe that Canada will not have enough water for its residents if it sells water to the United States. This is a myth. Toronto MP Dennis Mills says, “Many people just don’t understand the issue. They have this idea that the Americans are going to build the biggest pipeline the world has ever seen and drain the Great Lakes dry.” There are many proposed diversion schemes that would have minimal effect on ecology. The water diversion scheme in Manitoba is an example of this. It proposes that an insulated pipeline be stationed at the mouth of the Nelson River just before it empties into Hudson Bay. This scheme would allow the Nelson River to run its full, natural course and only divert 1% of the fresh water that is currently being emptied into Hudson Bay. The Canadian people have being misled that the world is going to run out of water. According to cbc.ca, the amount of water on the earth has stayed the same for the last four billion years, and will not change. Canadians have enough water especially compared to many other countries. According to The Globe and Mail, Maude Barlow has said “…31 countries are facing water stress and scarcity and more than a billion people lack adequate access to clean drinking. By the year 2025, as much as two-thirds of the world’s population will be
In response to invasive species threats, Ontario’s Ministry of Natural Resources, Agriculture, Food and Rural Affairs, Environment and Transportation developed the Ontario Invasive Species Strategic Plan. Its objectives are to prevent new intruders from disembarking and subsisting in Ontario, to reduce and reverse the extent of remaining invasive species and decrease its damaging impacts. Ballast water is a well-known source for the introduction and spread of aquatic invasive species in the Canadian water bodies. In response, Canada and the United States placed strict regulations governing ocean-going ships and their ballast water. For example, requiring inspection and the flushing of tanks with salt water before entering other waterways. Collectively,
The story The Sniper takes place during the civil war in Dublin, where a single sniper waits on a roof top to eliminate any threat from the oposing forces. This story is very tense right from the begining as soon as he noticed the enemys watching him and a bullet comes close to hitting him. This story's opening is one that catches your attention and gets you really focussed on the story. The Most Dangerous Game on the other hand starts out with a reputed hunter falls off the yacht he was on and ends up on an unfamiliar island. In which he finds General Zaroff only then does the good part of the story begin, yes the start of this story was a bit
In 1988 Canadian government research scientists identified a 630,000- cubic meter blob of black oily oozing sludge, approximately 5-8 meters below the surface of the water, which is described as a “toxic Cocktail”. This sludge is the largest and most PAH(Heavy Metal)-contaminated sediment site on the Canadian Great lakes. It was identified as mainly coal tar, which is a by-product of the coking process that is necessary for steel making, but to this day no steelmaker, other business or person has ever been charged with causing this environmental mess.
Estuaries are known for being sensitive to several human activities, such as littering and building structures like dams and seawalls that affect their natural flow of freshwater. As estuaries can prevent nearby streets from flooding, they will consequently bring many of their contaminates as well (Baker), which can pose a serious issue for an estuary’s productivity and health. UFL geologist John M. Jager argues that “toxic substances and excess nutrients [from such human-made factors] contribute to fish diseases, algal blooms, and low dissolved oxygen,” all being a threat to the health of not only the estuary itself, but additionally that of its wildlife and even humans themselves.
While the Animas disaster avoided immediate and catastrophic results, the ultimate ecological price tag will take longer to figure. The river moves so fast that it swept obvious toxins downstream quickly. Yet the long-term toxicity reached hundreds and, in some cases, thousands of times over what is considered safe for the life beneath the river’s surface. That price will be silently calculated over months and years—by the trout.
Today’s society always has some form of social inequality, whether it be between gender difference or by one’s importance in society. There are so many forms of these inequality that the world always feels unbalanced to some people. Racism is considered to be a large social inequality. That is why in Harper Lee’s novel “To Kill a Mockingbird”, has a lot of examples of social inequalities and how it affects each character. It shows great examples of social inequalities of the novel’s town of Maycomb, Alabama.
about the problem with the water several days before they told the public about it. (In-depth:
The St. Johns River is suffering from a significant environmental disaster because of toxic substances from municipal and industrial wastewater, fertilizer runoff, failing septic tanks, and stormwater. Consequently, over 55% of the river miles, 80.4% of acres of large water bodies, 59.4 % of estuaries, and 31.4% of coastline miles do not meet water quality standards in Florida (Florida Department of Environmental Protection 119). For that matter, studying those pollution problems that the river faces is vital since one can use this information to salvage the natural resource which is at the brink of destruction.
The world of today is very different from the world of yesterday. Overfishing affects the economy and could cause major disruptions to the environment of Canada. However, people can ponder about the importance of the impacts that overfishing could cause in
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.
In a world which she defined as ‘social science fiction’, Margaret Atwood brings clarity and life to a situation many would deem unimaginable. Those who immerse themselves in her novel are still able to see it as a dystopian society and thus detach themselves from the text itself. The readers comprehend the apparent loss of freedom and pain that the characters go through and have the knowledge that they exist outside of this story; its happenings will not affect them. This very phenomenon is introduced in The Handmaid’s Tale when the main character recalls a time before the fall of society as they knew it. Regarding the stories in the newspaper, the main character says that “We were the people who were not in the papers. We lived in the
