Introduction
The Great Lakes together form the world’s largest fresh water system. They supply a significant amount of the world’s fresh water supply. The great lakes are not only an important source of fresh water, these mast bodies of water also are known to be a home for many wildlife species. For many years the Great Lakes have served as a dumping ground for many harmful pollutants. From industrial waste and drain pipes to pesticides and fertilizer runoff s the Great Lakes are suffering. Damage of this kind produce harmful conditions for the fish, wildlife, and humans dwelling in the surrounding area of the region.
Sources of Pollution in the Great Lakes
Earlier age industrial companies, such as pulp and paper, operating near the Great Lakes region dumped waste including mercury into the water using pipes and/or vessels. Some of this polluting was done involuntarily with the malfunctioning of these pipes or vessels. Other times were intentional sticking to the theory that water “neutralizes” all substances.
Fecal matter was another strand of pollution found in later experiments performed on the water of the Great Lakes. The source of this pollutant was believed to be sewage. Sewage is known to house many bacteria including two of the most harmful, E.coli and enterococci (Liu et al 2006). Pollutants of this kind cause the water quality to decline and bacteria growth to increase (Shear 2006).
Other forms of pollutants that affect the Great lakes include air-bound, pesticide and fertilizer runoffs. These pollutants affect the Lakes involuntarily. These pollutants…...

..., “…the air quality of the Ontario Lake Huron Shoreline is among the worst in Southern Ontario.” “Other chemicals that can be deposited into Lake Huron via the atmosphere include pesticides, lead, mercury, PCBs, furans and dioxins.” Figure 1: Pathways of Pollutants (The Lake Huron Centre for Coastal Conservation) This practice results in harmful bacteria which causes the decline of water quality and increase of bacteria growth (Shear, 2006 as cited by Pollution's Effects on the Great Lakes Ecosystem). Regardless of the source, the water quality of Lake Huron can affect wildlife, as well as humans. Pollutants will inevitably find their way into the food chain and cause illness or death. According to (Liu et al, 2006, as cited by Pollution's Effects on the Great Lakes Ecosystem) …”studies have shown that two kinds of bacteria (enterococcus and E. coli), which are indicators of human fecal matter, were present in 20% of the samples taken from Lake Michigan beaches in 2004. Whereas, Shear, 2006, as cited by Pollution's Effects on the Great Lakes Ecosystem) states that, “If ingested by humans, these bacteria could cause such illnesses as extreme as typhoid fever.” In Liu’s opinion as cited by (Pollution's Effects on the Great Lakes Ecosystem) “Infections, gastrointestinal diseases, and parasites are other possible risks from coming into contact with these bacteria….” As a result of fecal matter pollution that has been plaguing beaches on the Great Lakes, there was a......

It is clear that when the concentration of certain chemicals (like PCB and toxaphene) decrease, biomass increases. Figure 6 biomass_pcbconc.png As the concentration of PCB increases, biomass decreases and vice versa. Figure 7 biomass_toxapheneconc.png As the levels of toxaphene concentration increases, the biomass decreases and vice versa. Other Effects of Harmful Pollutants on Great Lakes Wildlife DDT, known for causing the thinning of birds’ egg shells, is another example of the direct effect pollution can have on Great Lake wildlife. Used as a pesticide following World War II, the pollutant greatly reduced bird populations throughout the region, including such species as osprey, Forster’s terns, herring gulls, and double-crested cormorants (Michigan Department of Environmental Quality 2000). Dieldrin, another pesticide, is hazardous not only to Great Lakes wildlife, where it reduces fish and other species populations, but it affects humans as well. The pesticide is known to regularly contaminate fish humans consume, and has been found to......

Effect of Water Pollution on Lake Huron

... pollution. Waste from hospitals and burning of fossil fuels produces large amounts of mercury in the air. This happens as the pollution moves through the air and is deposited by rain or snow such as acid rain. Lake Huron is 850 cubic miles or water, has 3,827 miles of lakeshore, it is 206 miles across, 183 miles north to south and has an average depth of 195 feet. Lake Huron’s 23,000 square miles of surface area has made it very vulnerable to atmospheric deposition of contaminants. This is the major cause of pollution to Lake Huron because it has few local contaminant point sources. Sediments and land runoff are continual sources of pollution to Lake Huron. Some of the toxins include phosphorus, dieldrin, DDT, furans, dioxin and PCB’s.  Part of Lake Huron Shoreline The pollution in Lake Huron has a negative effect on people and the economy of the area. Phosphorus levels threaten the safety of drinking water because of the harmful algae blooms. Deficient oxygen levels because of excessive algae growth makes the fish communities unstable and harmful for consumption. It can cause the extinction of a specifies which disrupts nature’s balance and creates harm to other species. The economic affects are just as devastating. Lake Huron beaches are enjoyed for local residents and tourists every year. The pollution in Lake Huron will reduce the tourism to the area and cause local residents to go elsewhere to spend their money. Property values decline due......

Cause and Effect on Pollution in Lake Huron

...Water quality has become a major issue along the southern shores of Lake Huron in recent years. The sources of this pollution are many, and the culprits as equally diverse. Nonpoint-source pollution is another term for polluted runoff. Water washing over the land, whether from precipitation, car washing or watering crops or lawns, picks up an array of contaminants including oil, sand and salt from roadways, agricultural chemicals, and nutrients and toxic materials from both urban and rural areas. The term nonpoint is used to distinguish this type of pollution from point source pollution, which comes from specific sources such as sewage treatment plants or industrial facilities. •Pathogens Pathogens are disease causing microorganisms, such as bacteria and viruses that come from the fecal waste of animals and humans. Pathogens wash off the land from wild animal, farm animal and pet waste, and can also enter the lake from improperly functioning septic systems, leaky sewer lines and boat sanitary disposal systems. •Nutrients Nutrients are compounds that stimulate plant growth, like nitrogen and phosphorous. In high concentrations, they can become both an environmental and health threat. Nutrients in polluted waters can come from agricultural fertilizers, septic systems, home lawn care products, and yard and animal wastes. •Toxic Contaminants Toxins are substances that can harm aquatic and human life. They are created by a wide variety of human practices and...

...Cause and Effects of Water Pollution in Lake Huron Litiecha A. Lee English Composition/115 Saturday, November 17, 12 Jeanette Trammell Cause and Effect of Water Pollution in Lake Huron The North American great lakes including Lake Erie, Michigan, Huron, Superior, and Ontario, are the largest fresh water supply and home to many of the world’s wildlife. Lake Huron is the third largest of the lakes by volume of water. It average depth is 59 meters and it has a maximum depth of 750 feet. The following paragraphs will outline a major cause of pollution in found in Lake Huron, a secondary cause, two contributing causes, its effect on humans, and the effect pollution found in Lake Huron has on the economy. The pollution in Lake Huron has a negative effect on the vegetation, wildlife and humans. Sources of pollution in the lake are diverse, over the years pollutant sources were separated into two categories, point source and non-point source. The point source of pollution in Lake Huron was due to an earlier belief that water can melt and neutralize waste and chemicals. Because of this belief, in the early nineteenth century and part of the early twentieth century sewage was released directly into the lake waters during a storm to avoid sewage overload. According to Shear, H. (2006), “Both sewage and other organic wastes cause the water quality to decline and bacteria growth to increase.” Today the process has changed or is in the process of changing...

... questionnaire was used to gather information about school adolescents’ dietary, their sources of nutrition information and selected food skills-food preparation and the types of dietary advice given to friends and relatives”. This world helps decide a nutritious way and better meals for kids at school. “Food skills such as shopping, meal planning and meal preparation have been found to be important determinants of the eating habits of adolescents; these skills assist adolescents in making effective food decisions later in life” (Brown et., 2000). Even though kids are eating school lunches they will not be healthy now or in the future if this continues. Kids getting unhealthy menus cause them not to get enough nutrition. Schools should consider how many calories, vitamins, and nutrients kids’ intake daily. The benefits kids can gain from this are being healthier and having more energy from the fruits and vegetables. It also helps them pay more attention in school. Eating yogurt, cheese, and drinking milk is also healthy and builds up the calcium (Ministry of Health, 1991). For instance, here are some nutritious, health, and dietary foods that are generated on the illusion of the Nutrition Food Pyramid below that show examples of how eating healthy can be. “An Illusion of the Nutrition Food Pyramid” Some kids do not eat lunch at school, but they should because now school lunches probably are very healthy for them.

While on the positive side many students will not be willing to purchase nutritious foods, if they are fully aware of how eating healthy impact their health. You want this last sentence to be positive, am I correct? I would take out “while” and “the”, change “positive side” to “positive note” and say something positive such as “On a positive note, if the students were more aware of how healthy eating makes such an impact on their lives, they will most likely eat healthier”.

... Conservation (LHCCC) this type of pollution is known as “Point Source Pollution”. A Leading Second Cause of Pollution in Lake Huron Another major factor of pollution in Lake Huron is “Nonpoint Source Pollution” which is the result of water runoff that eventually finds its way into the lake through natural processes. Nonpoint Source Pollution comes from all walks of life from farms, cities, factories and even individuals. This water runoff contains contaminants and chemicals which have a negative impact on the water quality of Lake Huron and can kill or give disease to natural inhabitants of the lake (LHCCC n.d.). Other Contributing Causes of Pollution in Lake Huron Other causes of pollution in the Lake are the air quality pollution as the pollutants which we release into the air also have an impact on Lake Huron air quality and this in turn contaminates the lake and its denizens. According to the Environment News Service (ENS), Lake Huron is second only to Lake Erie in the amount of pollution in the air in the region (ENS, 2005). Climate change and pollution have also had a contributing effect to the rapid growth of algae in Lake Huron. While most algae is harmless, some species of the algae which are thriving in Lake Huron and the other Great Lakes have harmful effects on the water quality of the lake, the fish and also on humans as they release toxins that can be health hazards to both humans and aquatic life. Algae blooms can also foul up coastlines, the hulls of......

...It is important to the wellbeing of animals, humans, and the environment that our society had clean water not only in and around areas of Lake Huron but for the world as a whole. “About 70 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers.” (How much water is there on, in, and above the Earth?, 2013) The impact of polluted water can affect many different sources that can greatly impact our society in a negative way. “The effects of water pollution are varied. They include poisonous drinking water, poisonous food animals (due to these organisms having bio accumulated toxins from the environment over their life spans), unbalanced river and lake ecosystems that can no longer support full biological diversity, deforestation from acid rain, and many other effects. These effects are, of course, specific to the various contaminants.” (Rubin) In order to help prevent the negatives effects happening in Lake Heron, the public must be informed and governmental agencies need to create more action in improving this matter. Figure 1: (http://www.mnr.gov.on.ca/en/Business/GreatLakes/2ColumnSubPage/STEL02_173901.html) Lake Heron, located between Michigan and Canada, is the third largest bodies of water in the world and covers at least 23,000 square miles.

... contaminants. Point-Source Pollution refers to a direct source of pollution, such as pipes or other vessels. Early industries like pulp and paper companies located in The Great Lake region believed that anything could be dissolved by water. As a result, many wastes, like mercury, were dumped into The Great Lakes, They also found fecal matter pollution from sewage which causes harmful bacteria such as E Coli and enterococci. Both sewage and other organic and in-organic wastes cause the water quality to decline and bacteria growth to increase. Organic contaminants are discovered by testing the tissues and muscles of the fish that are found in The Great Lakes. Chloro-diphenyl-ticholoehane, aslso known as DDT, was found in all the muscle tissue testing. This chemical is the most common chemical pollutant found in The Great Lakes. According to the results from the muscle tissue testing, dieldrin is the second most pollutant in The Great Lakes. Lindane is also a very harmful insecticide that was found in the tissues of the trout and walleye in Lake Huron. Air pollution is also a big factor in the water pollution of Lake Huron. The air pollution from the industries around the Great Lakes take less than a day to reach the Lakes. With that, the air quality of the Ontario Lake Huron Shoreline is the worst in Southern Ontario. Canadian faculties have found more than one billion kilograms of pollutants in 2002 like smog and acid rain. This includes 3 million kilograms of...

Effect/Cause

...Professor Vollaro ENC 1101 February 4, 2013 Effect Cause Paper Illiteracy The society, the American economy, many people’s health, and even the justice system are all affected by illiteracy. The lack of the ability to read and write has a huge impact, one way or another, on the everyday life of every person. Twenty percent of the American population is functionally illiterate, which means they cannot read at all or they read below the fourth grade reading level. It is important to make sure as many people as possible are able to read and write to be able to complete all necessary daily activities, both at home and at the work place. A person needs to be able to read and write to fill out job applications, follow rules and directions, and maintain financial records. Some of the common causes of illiteracy are poverty, the lack of literacy within the family, and learning disabilities. Due to poverty some children are needed to work outside of the home, to help compensate the family’s income, instead of being able to go to school to receive the education that is needed. Therefore, poverty leads to the lack of literacy within the family. According to the National Center for Education Statistics, nearly twenty-two percent of all of the adults living in the United States scored below basic skills during an assessment in 2003 (“Illiteracy: The Downfall”). “Sixty years ago, most illiterate adults were people who were uneducated” (Kunerth). Today, learning...

... than surface weather. Seth Gutman, an atmospheric scientist at the National Oceanic and Atmospheric Administration in Boulder, Colorado is studying a new way to warn pilots of turbulence (Dorminey, 2014). By using the existing global positioning system to probe for atmospheric turbulence, one day a warning system could be in place to alert pilots to turbulence. Gutman explains that GPS signals are refracted and delayed by water vapor as the signals travel through earth’s lower atmosphere. “We take the signal delay info and put that into weather models, but instead of averaging this out over half an hour, we propose doing it over timescales of about a second at a time.” (Dorminey, 2014) Some air turbulence can be uncomfortable to make it through, but does not cause damage to the aircraft, but at other times air turbulence can be a nightmare. One example of severe air turbulence is when a DC 8 cargo plane in 1992, suffered severe air turbulence that took 12 feet of the left wing and the left outboard engine off the plane while flying over the Front Range of Colorado’s Rocky Mountains. Had there been some type of detection system in place this accident may not have happened. All in all, weather is the single most important uncontrollable factor in flight.

Some of them are extremely crazy and some are hilarious. The first time I met Bandar, a mutual friend introduced me to him, to give him a ride home. On that day, I knew a lot about him. His interests, the way he thinks, his family, and especially his anger issues. He is hot-tempered. His angry actions cannot be controlled, always get us into a bad situation, but we learned a lot from him. First, I learned to control myself in many situations because of him. He does not care about what he say or do to others; he just expresses himself without thinking of the consequences. Many people were bothered and even fought with him because his actions. However, both our friends and I know how to deal with him. In time, we could help him controlling his anger problems. Nevertheless, sometimes we cannot do anything but leave him alone to think and relax. That at least what we could do to a friend. Second, he taught me how important is to continue my education. Bandar was a school nerd who loves studying. He was very serious about his future career, and knew what he wants to be. Indeed, he finished his bachelor degree in 3 years with double major, Engineering and Business. Bandar wanted us to be like him, but not all of us has listened to him, only a few of us are still pursuing our education. Now many of our friends...

Cause and Effect Analysis

... to come up with a solution. This needs to be done so that the problem can be solved completely the first time around, rather than just addressing part of it and having the problem run on and on. This process is called “Cause and Effect Analysis”. Professor Kaoru Ishikawa created Cause and Effect Analysis in the 1960s. The technique uses a diagram-based approach for thinking through all of the possible causes of a problem. This helps you to carry out a thorough analysis of the situation. There are four steps to using the tool. [1] 1. Identifying the problem and/or goals 2. Brainstorming; Work out the major factors involved 3. Chart Analysis; Identify possible causes 4. Analyse your diagram & develop an action plan Cause and Effect Analysis can be used for both; looking forward to plan a chain of events, or looking backward to better understand one. Cause and Effect: Looking Back Cause and Effect analysis is typically used to figure out why something went wrong. However, it can also help you to replicate a positive outcome through the thorough results from the tool. Cause and Effect: Planning for the Future Although, “Cause and Effect Analysis” is classically used to understand previous events (usually to avoid repetition), it can also be used to help plan for the future. Rather than attempting to explain an existing outcome, it is possible to set up a hoped-for outcome, and then analyse the elements required to bring the outcome about. Once you have a...
