2013).Pharmaceutical companies sometimes place active chemicals and waste into groundwater sources, in which almost all of the groundwater may be untreated which most likely cause contamination. (Herber, 2002). Abstract: Increase in the emissions of carbon dioxide by burning fossil fuels is the largest cause of environmental down grading resulting not only in global warming but also causing acid rain which alters the pH balance of ground water. Water is a universal solvent; however, its dissolving properties are very sensitive to changes in temperature and pH. Global economic growth has, unfortunately,
Beach closures have also been more frequent being something many families, and residents have once enjoyed. These toxic chemicals have been found in fish and wildlife, which have been deposited into the lake by manufacturing sites and other industrial companies. (Glutting, 2003)Runoff pollution, pollution that comes from a single location has also added to the lake’s devastation. Storm water, irrigation runoffs, sediments, fertilizers, and fecal matter deposits, are some of the discharges contributed by sewage treatment plants. These runoffs have contributed to the beach closures, and the unsustainable condition of biological life in the lake.
Cinnamon Fungus Violet Westringia LERDERDERG STATE PARK FLORA The Lerderderg State Park have over 350 species of flora are found at the park. 28 of those 350 are listed as rare or threatened species. 17 plant species are listed as pests of the park. The majority of these are confined to the more damper environment of the gorge and park boundaries. Weeds are also very common within the park.
1. Define the Superfund Program The federal government’s program to locate and investigate and clean up the worst uncontrolled and abandoned toxic waste sites nationwide; administered by the EPA - Environmental Protection Agency. 2. Identify a Superfund site within your own state. There are a lot of sites in the state of Michigan.
Most disturbing are the attacks on very young Lodgepole Pine as a lot of this volume has actually been reforested from previous cutting and contributes to the province’s sustained cut (AAC). The AAC is now threatened not only from losing mature volumes but also losing the successive regeneration that we have come to rely on for the future. On their own, the beetles can fly 1 or 2 kilometers (kms), but with the right wind currents can fly more than 100 kms, which explains their ability to cross the Rocky Mountains into Alberta. This is significant in terms of threat as it now becomes a National concern with the MPB has adapting to attacking the Jack pine forests that cover areas of Alberta, Saskatchewan, Manitoba, Ontario and
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
With reference to one or more located examples, describe and explain the different impacts of flooding (25 marks) Floods can have a major impact on the environment and society. The impacts can be social, economic, and/or environmental. Although the vast majority of the social and economic impacts are negative because they result in costly repairs and the disruption of peoples’ everyday lives,, some of the environmental impacts can be positive. For example, floods spread sediment containing nutrients over soil that may not have reached had there been no flood. Whether or not a country can cope with the effects of a flood depends greatly on whether it is a less economically developed country (LEDC) or a more economically developed country (MEDC).
Chemistry Current Event Name: Andrea Rebecca Priest Due Date: 04/18/13 Article Title: Puny plastic particles mar Lake Erie’s waters / Environment Date of Article: April 12, 2013 Source: ScienceNews Author: Rachel Ehrenberg Summary: Researchers have been studying the effects of pollution on the Great Lakes for some time. In one of their recent studies, Lake Erie, part of the Great Lakes, contained a great amount of small particles of plastic. These pieces of plastic have highly toxic pollutants and the samples that were collected from the lake make up about eighty percent of it. Researchers have found that these particles soak up other pollutants, but they are not sure if it affects the wildlife creatures when they consume
Dead Zones There are numerous dead zones found around the world and the number is expected to double in the years to come. One of the largest dead zones is located in the Gulf of Mexico. Studies have shown that nitrates from fertilizers, which are used by the farmers, runoff into the Mississippi River then eventually makes its way to the Gulf creating the Dead Zones. In order to stop the ruination of the natural environment, actions need to be taken immediately if we are to protect and improve our waterways. Dead Zones occur when dissolved oxygen levels in the water get so depleted the water cannot support life.
Conclusion Pollution within the Great Lakes is a serious problem that effects the ecosystems within the lakes and has effects on humans as well. These pollutants are causing problems that are preventable and need to be and are being looked after by the governments. Actions can be taken to control our harm to the lakes and we need to outweigh the negatives to our actions over the positives. It is not blatantly seen, but our actions towards the way we treat the environment has an ecological impact all throughout the world.
