Companies have deposited their waste in the lake, which has caused the lake to be shut down because humans are getting sick and even dying from the polluted waters. Viruses, pathogens, chemicals and toxins are all part of this pollution, which affects recreation, jobs, and habitats of animals. Fishermen have not spent money fishing for sport due to the drastic reduction of the salmon population at Lake Huron. Recreational hours at the lake have also seen a drastic decrease. This devastation affects a majority of the U.S. being one of our largest sources of fresh water, and will only continue to deplete, as companies carelessly dump their waste into the lake.
The air quality on the shoreline of Lake Huron is the worst in the south Ontario area. (Sivers, A, n.d) Sediment loading is known to high levels of deferred solids being washed into creeks and rivers and carried down into the lake. (Sivers, A, n.d) Sediment loading can also be caused by dredging which can cause a decrease in food source for the aquatic life. With having foreign vessels follow in and out of the lake from the Atlantic is also causing problems. With the vessels having foreign aquatic life attached to the bottom of the ship and also leaking fluids into the lake while passing through.
Aquatic Invertebrates: Adaptations and Feeding Guilds INTRODUCTION Global warming and human's authoritative influence on the environment such as deforestation, pollution etc. are taking a bad toll on the diversity of the ecosystem. Global warming which has brought about increase in the temperatures is disturbing the natural cycle of the ecosystem. This has brought upon an increased droughts throughout the world. The droughts and increased heat has had negative impacts on local aquatic invertebrates.
It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes. The phosphorus levels in Lake Erie are increasing due to the pollution causing harm to the fishes that reside in it. In 2014, Lake Erie had so much algae from pollution that it caused the City of Toledo to be left without fresh water. This algae was caused by the excessive amount of phosphorus in the lake. This excessive amount of Phosphorus is caused when the fertilizer is dumped into the lake by farmers.
2. Do background research – Utilizing at least one scholarly source, describe how variations in dissolved oxygen content in a body of water can affect fish populations. Answer = “Oxygen depletions are the most common cause of fish kills in ponds. (Aquaplant, 2014).” Based on my observation of the chart and what I read, the higher the dissolved oxygen levels the number of fish drops. Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases.
As the reliable water sources shrank and they were forced to drink the contaminated water. This may have also spread diseases throughout the Colony. The results being more deaths, because of the water sources being contaminated by filth from the colonists. [Doc.B] Shows that there was a large time of drought from 1606-1612.This likely affected the growth of crops. The result was deaths most likely caused by lack of food.
When we refine or even dig up oil sands we produce harmful chemicals. Since Alberta oil sands are located near major rivers some of those chemicals end up in the rivers. The most famous case is with the Athabasca River, where the water is contaminated by many harmful chemicals. The Athabasca water ecosystem is slowly being poisoned and so are the people that use the water for their water supply. The oil sands maybe a large part of our social and economic structure, but they are slowly ruining our environment.
SO2, sulfur dioxide effects our trees and water systems and is the prominent cause of acid rain. Mercury- when Mercury enters our water systems it becomes harmful to our ecology (fish, plants, animals etc) and effects anyone who consumes part of the food chain. Nitrogen
The effects of human development have polluted the waterways of the state as well, making it difficult for native fish to survive long enough to breed. Pictured at the end of the document is a model of the food chain in the rivers and lakes of
Another item pointed to pesticides, fertilizers and road salt as additional contributors to the pollution problem. And even further a New York Times article spoke about the algae blooms resulting from phosphate pollution. The lake has experienced a decline in its fish production attributed to the “dead zone” resulting from algae blooms. Further, the fish caught have ingested plastic and plastic the article argues attracts chemicals like bisphenol A (BPA) a contaminant said to affect the endocrine system. This
