These pollutants have reduced water quality, contaminated soils, and damaged the Lake’s ecosystems. Pollution in wildlife has caused fish consumption to decrease, the spread of disease and viruses to increase, loss of fish and other wildlife stock. The closing of beaches and other recreational activities have been another direct result of the
Hoses can be undone, gaskets can fail, pits leak and liquids always hit the ground, repeatedly in large quantities. Fracking needs a lot of work to be done before it can begin obtaining oil. The fracking fluids have a lot of toxic chemicals and become even more contaminated when pumped down a hole as they travel through rock formations before returning to the surface as flow back. The liquids can cause ground contamination and even in small portions can contaminate shallow aquifers with hydrocarbons, toxic chemicals, heavy metals and radioactive
To what extent to you agree with the view that the hazards resulting from earthquakes and volcanic activity cannot be managed but merely adapted to. Earthquakes and volcanic activity are both nature disasters that human can’t control when or where it will happen and it may cause lots of death and economic loss. There is no way that we can stop it from being happened but we can definitely try to adapt it by many different ways. Firstly, volcanoes are found at destructive and constructive plate margins. At destructive plate margins, the oceanic plate goes under the continental plate due to it’s more dense, which is a process known as subduction.
Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming. Fracking has been linked to movement of radioactive materials and heavy metals from the underground layers of the earth to the surface through flow-back
'The extent to which volcanic processes represent hazards depends on where and when they occur.' Discuss this statement. Volcanic processes become a hazard when they impact upon the human and built environments, killing and injuring people, burying and collapsing buildings, destroying infrastructure and bringing agricultural activities to a halt. Volcanic hazards are influenced by several factors including location, time and frequency of eruptions, and the materials ejected. It is the viscosity of magma that largely determines the nature and power of an eruption and the resultant severity of the hazard.
The procedure consists of injecting a special fluid made up of chemicals and sand into the ground at high pressures to squeeze the natural gas back up through the rocks. By injecting this certain fluid we are leaving mercury, lead, hydrochloric acid, methane, and other poisonous chemicals left to rest in our earth’s crust. Studies show that more than 90% of fracking fluids are left underground. Because we are permanently polluting our land we are putting our environment at high risks of becoming destroyed and it is effecting human health. One resource that is at high risk of being contaminated due to fracking is water.
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
Sulfuric Acid is a strong acid that exists as a colorless oily corrosive liquid and is made by reacting sulfur trioxide with water. This is most commonly found in batteries, manufacture of fertilizers, explosives, detergents, dyes and other different chemicals. Sulfuric Acid is very dangerous to humans as it can cause respiratory tracts of humans and other animals while doing some major damage to plants that helps provide oxygen for us. Ground-level ozone is a secondary air pollutant formed when sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons. If a human inhales ground-level ozone it can cause chest pain, throat irritation, and congestion.
Furthermore, the influx of chemicals brought deep into the ground for extraction purposes have mixed with ground water, leading to lethal contamination of local drinking water. Amongst these results, fracking often yields high amounts of methane gases to the atmosphere. If fracking continues at high rates it will evidently threaten local habitats while also contaminating ground waters and while polluting
