Eversince the invasion of Zebra mussels in 1988 the ecosystem of The Great Lakes suffered negative impacts from decrease of plankton to spending big numbers every year to try to remove them from the ecosystem. But little do people know they also help brought Lake erie (one of the 5 great lakes) back to life, during the 1970s Lake Erie was declared dead since massive amounts of pollution were dumped into the Lake from agriculture industry. The pollution caused the Lake to have less oxygen which caused some parts of the lakes to be a dead zone. Overall this can be concluded to have negative impact to the ecosystem of the Great Lakes, but there are some positive impacts too. The primary objective should be to remove the Zebra mussels from the great lakes even though the had positive impacts, the zebra mussels don’t belong in this ecosystem.
Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years. Also, the usage of explosives are harmful because they all kill off things such as coral, and the damaging of coral reefs can take decades before it reverts back to its normal state. To reduce or totally eliminate the way these local practices are impacting the environment, we can place restrictions on what can be used in fishing, and how much you can catch. For example, we can limit fishers to only 10 fish a day. This would give the fish plenty of time to reproduce and would keep the population of the fish steady.
Also, the ocean filters the air we breathe, and like said before, supplies 80% of the oxygen we breathe. Pollution causes the ocean not to function properly and oxygen levels can and will diminish. The ocean is also home to medicines that treat heart disease, cancer, and more. The plants or animals that give us these medicines are endangered as long as marine pollution exists. The remedies can be lost causing more people to die because of the lost medicines.
Other invasive plants are Melaleuca, Old World climbing fern, Australian Pine, Brazilian Pepper, and Seaside Mahoe. Power plants released mercury to the atmosphere and fell to the water as rain. Phosphorus and mercury caused water pollution and negatively affected many animals and the ecosystem. Many panthers were found dead. We have to improve the water quality in the Everglades otherwise more animals are going to die.
Overfishing has drastically changed marine environments in many ways, species have gone extinct, and environments have depleted. If overfishing continues to occur our society won’t have the marine life that we are very dependent on. Ever since the 11th century, overfishing has been a problem. Many fishermen have overused local and regional ecosystems, which led to destruction.This resulted in a major reduction of stocks in fish and marine mammals. After destroying one ecosystem, the fishermen would
Many colonists died because of the environment. The main reason the enviroment killed them was because of the contamination of the water, and tides. The contamination of the water happened when they dumped their waste into the river. The colonist thought the waste would wash up but instead it “tended to fester rather than flush away” according to document A written by Denni Blanton of William and Mary College. They would later drink the water and they would get ill and eventually die from diseases.
This is also an organizational problem which highly escalated the spill because if exxon had thought ahead and had a good plan, in the case of an oil spill, they would have been able to maintain the spill better no resulting in so much damage. The oil spill effected the whole nation, but mostly the people in Alaska. All aspects of Alaskan life were shaken, including economic, cultural and social. Alaska is known for its great quality and quantity of fish. The oil spill took a huge tool on alaskas fishing industry, forcing many Alaskan citizens which depended on the fish for their income to be pressured into some kind of a depression.
This also has a big part of why salmon are going extinct. ("Sockeye Salmon" 2017) In order to save the salmon people are needing to let nature take its course by letting the rivers flow free to take down the dams and, minimize the amount breeding in the fish hatcheries. People have had too big of an effect on salmon by building dams, causing climate change, and straightening rivers. The human effort alone is causing the population and size of salmon to decrease. ("Salmon Information, Facts, and Photos") This decrease is causing a lack of nutrients in the water and forests.
News of the poisoned water crisis in Flint has reached a wide audience around the world. The basics are now known: the Republican governor, Rick Snyder, nullified the free elections in Flint, deposed the mayor and city council, then appointed his own man to run the city. To save money, they decided to unhook the people of Flint from their fresh water drinking source, Lake Huron, and instead, make the public drink from the toxic Flint River. When the governor’s office discovered just how toxic the water was, they decided to keep quiet about it and covered up the extent of the damage being done to Flint’s residents, most notably the lead affecting the children, causing irreversible and permanent brain damage. Citizen activists uncovered these actions, and the governor now faces growing cries to resign or be arrested.
This impacts our well being because, according to the website: The Mekong River- Survival for Millions, the water from rivers are the source of most of our drinking water. Eutrophication causes an abundance of bacteria to form in the river. If there is too much bacteria in the water, it will cause sicknesses and negatively impacts our health. However, if there is too much manure in the water, it will contaminate the water and negatively affect our health as well. This is why we should use animal manure in moderation.
The Flint Water Crisis is a state emergency in which the government decided to save money by switching over their main water source from the Detroit River, to the Flint River. This resulted in the residents of the city of Flint to be poisoned. The horrible conditions of the Flint River water caused lead to get into the water supply from the old pipes. This meant that the water was toxic with extremely elevated lead levels. Between 6,000 and 12,000 young children were exposed to drinking water with elevated lead levels in it.
Aluminum Phosphide is used in other countries to preserve food. This compound was also often used in pesticides but the use of it decreased due to accidental deaths that occurred. The recycling of used Aluminum Phosphide caused the death of family in Spain. When it reacted with water, death occurred within hours. The most recent problem with this substance happened on January 3rd 2017 when 4 people were killed: a senior and her 3 brothers, the youngest being 7.
Recent studies have shown that the water in Flint, Michigan has been contaminated by a horrible health impact, lead. This has happened because nearly two years ago, the state of Michigan decided to save money by switching Flint’s water supply from Lake Huron, to the Flint River a notorious tributary that runs through town known to locals for its filth. This has led to many terrible effects shown in both children and adults. The many effects lead has on children and adults are very drastic if not taken care of properly they could have lifetime effects. Dangerous effects lead can lead to that effect children.
Red Tide: How it affects Marine Life Red tide in Florida is a reoccurring problem that threatens marine life every year. Red tide in Florida waterways has a negative impact on marine life because it produces toxins that are harmful to marine species. It lessens the amount of oxygen in the water which ultimately leads to the migration and death of many different marine animals. Millions of dollars are poured into red tide research and prevention every year to help predict when and where a red tide is going to form. All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life.
These companies release toxic fumes into the air we breathe, and in some cases dump toxic waste into lakes and rivers directly affecting the environment, aiding to poor air quality and toxic water. According to the EPA Sumner County ranks between the 80-90% bracket for being the dirtiest/worst for having water sources with impaired or threatened uses. With the high levels of metals in the environment it is an environmental injustice. Not only are humans affected by toxic pollutants, these chemicals also pollute the homes of many fish and birds that claim home to the lakes and rivers of Sumner County. We have to make sure our fish and birds live in clean water so they can promote diversity in the
