The ozone protects us from the majority of the harmful rays from the sun and it shields us from most of the sun’s heat. When we first found the oil sands they were covered with trees, shrubs and other plant life, to get to the oil we had to clear-cut. The clear-cutting destroys many habitats of animals. When an animal looses it’s habitat it either dies or it runs to the city, where it can be a potential threat. When we refine or even dig up oil sands we produce harmful chemicals.
It is the viscosity of magma that largely determines the nature and power of an eruption and the resultant severity of the hazard. Basic magma has a high proportion of dissolved gases and low silica content, making it very fluid. On the other hand, acidic magma is very rich in silica and has a relatively lower temperature, making it very thick and slow moving. The more viscous the magma, the greater the potential for explosive eruptions and these represent the greatest potential hazards. Non-explosive eruptions tend to produce mostly lava flows, which do not represent a particularly serious hazard to people, however they will destroy farmland and buildings.
Hydraulic Fracturing: The Inefficient Fuel Source Accoring to Treehugger, hydraulic fracturing requires 80 to 300 tons of chemicals to frack a single oil well. Hydraulic fracturing is the process of extracting shale gas deposited in deep underground wells by injecting water, sand, and disclosed chemicals into the ground at high pressure (Weighing the Risks of Fracking). Fracking is a non-renewable energy source that is very harmful to the environment. Hydraulic fracturing should be discontinued because it harms the environment, it requires a plethora of water, and because it has been linked to causing earthquakes (Jordan Howard). The chemicals that are used in the fracking process aren’t disclosed to the public.
first aide- move victim to fresh air, administer o2, remove all contaminated clothing, if in contact with eyes flush for 20min and wash the skin with soap and water. Immediately cool burned areas with warm water and don't remove any clothing stuck to the skin. Carbon monoxide- gas toxic and flammable. Extremely toxic when inhaled or absorbed though the skin. Isolate area for 100 meters in all directions.
These types of lava are very viscous due to its high silica content. This is because the lava rises from the subduction zone through continental lithosphere which has a low density and is filled with air spaces containing gases which become incorporated into the lava. This very viscous lava often blocks off vents of volcanoes and when the pressure building up in the vent is eventually released, the top of the volcano can be blown off leaving a huge crater, such as in the 2002 eruption of Mount Etna in Sicily. When the two plates involved are oceanic, explosions tend to be less violent than this as the melted lithosphere which forms the lava is denser and so contains fewer gases. At constructive boundaries where plates are moving apart from one another, basaltic lava is erupted between the gaps.
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.
Some mining involves the inadvertent dispersal of heavy metals, such as lead, into the atmosphere. This can have serious health effects 4. What can be done to prevent mine drainage from damaging the ecosystem? Utilize at least one scholarly resource to support your suggestions. Answer = According to World Coal, there are mining
Benzene has been known to be a carcinogen, while the rest of the chemicals are unknown what long term damage it could cause. Another danger of fracking are spills. Spills occur during the adding of the fluids as well as during the results of the flow back. Drill operators will eventually have spills throughout this process. Hoses can be undone, gaskets can fail, pits leak and liquids always hit the ground, repeatedly in large quantities.
Fracking is inherently risky, there is extensive evidence to suggest that fracking can contaminate groundwater and that it causes significant air pollution. For the first time in history, smog has become a major issue in many rural communities in the US, with some villages in Wyoming experiencing worse smog than downtown Los Angeles and an increase in lung cancer cases of over 500%. Since 2005, 1.2 trillion litres has been wasted in the fracking process creating toxic waste which cannot be recycled and must be disposed of very carefully to avoid danger to humans and the environment. In addition, one in six deep injection wells examined have an integrity violation leading to the leaking of toxic waste into the environment – more than 17,000 violations in the US alone. Such is the desperation for energy in the US, fracking has had to be made exempt from parts of at least seven major national statutes, including the Clean Air Act, Clean Water Act and Safe Drinking Water Act in order for it to be made legal.
Some of the major negative economic effects of natural gas drilling are the enormous amounts of pollutants released into our water sources. With estimates coming close to 50 trillion cubic feet of natural gas sitting in the Marcellus, it’s no wonder companies are willing to drill at any cost to the local water systems and communities. In other words, there is conservatively two trillion dollars in nature gas reserves sitting right under us. The problem with fracking is being able to find an economical and environmentally friendly way to dispose of the waste water. There are approximately thirteen treatment plants used to deal with the waste water that is accumulated by the massive fracking operations all over the state.
