Effects Of Fracking On The Environment And Human Health

As nations search for less carbon intensive forms of energy the demand for gas has grown rapidly worldwide in recent years. This significant increase in demand has led to a boom in world gas prices. In Australia, there are large reserves of unconventional natural gas compared to conventional natural gas. However, according to the Bureau of Resource and Energy Economics (BREE) there is enough conventional natural gas in Australia to supply all of Australia at current levels for more than 6130 years. Fracking extracts hydrocarbons from previously inaccessible sources of oil and gas using hydraulically pressurised liquid to fracture rock and release gas trapped in coal seams (Hester, R Harrison, R). This gas was once unprofitable because†¦show more content†¦Can contaminate groundwater that local landowners that farmers and local communities need.

Seismic surveying needs to be undertaken to determine where resources lie, seismic surveying has a detrimental impact on ecosystems – weed spreading, land clearing, dividing up and disturbing landscapes for access roads. Major reasons for water contamination from shale gas fracking operations: Well casing failure due to corrosion or faulty construction. Disposal of fracking â€Å"flowback† fluids, the water mixed with fracking chemicals must be store and then disposed of after the fracking of each gas well. Storage and disposal of used fracking fluids can contaminate surface and/or ground water. Emissions happen at point of both extraction, combustion and processing of the gas. Gas fracking releases methane into the atmosphere which is a powerful greenhouse gas. The health impacts The chemicals used in fracking are of concern. Current lack of research in this area. National Toxics Network produced a statement saying that â€Å"Our investigation found that of 23 common fracking chemicals used in Australia, only 2 have ever been assessed.

The children were to be obedient to their parents and follow the ways of â€Å"pureness† outlined before them. They were to serve God and not participate in any form of witchcraft. The Puritans believed that anything that happened was either an act of God or the devil. However, the children loved the stories told by Tituba, a Barbadian slave, belonging to Reverend Parris and dancing around the fire.

Abigail also accused Mrs. Proctor of being a witch, in revenge for firing her for having an affair with John Proctor. Salem was in an uproar. Reverend John Hale, an expert on witchcraft, was called in to help flush out the witches. Judge Hathorne and Judge Danforth presided over the witch trials.

The Keystone Pipeline Is A Pipeline - 2205 Words

The Keystone Pipeline The Keystone Pipeline is a pipeline based in Alberta, Canada that transfers up to 830,000 barrels of oil into the United States daily. The pipe is 1,179 miles long, ending in Steele city, Nebraska. Although about 61 percent of Americans approve the pipeline, there are many environmentalists and other U.S citizens who are against the pipeline and the dangers that may come from it and the effects it could have. Supporters of the pipeline claim that it could create thousands of jobs for the unemployed. It would also increase the security for the Gulf Coast and create a safer way of transporting oil. The environmentalists that are against the pipeline claim that it could increase global warming and damage the†¦show more content†¦Most construction workers are already employed, but look for other jobs to continue their work. This could mean that although there are many jobs available, many of those could be taken by Americans who are already working, not just unemployed Americans. Economist claim that since the United States depends on oil so much, this project would definitely be a huge asset to the country. Right now, oil is usually transferred using the railing system. There have been many accidents involving trains with oil, which have caused explosions, fire and in turn, death. Economists argue that the pipeline would be the safest way to transport the oil without the dangers of trains. Hundreds of activists have rallied all over the country to stop the approval of the pipeline, claiming that it is incredibly damaging to the environment. Most environmentalists argue that the pipeline will cause deforestation, oil spills and runoffs of toxins. Supporters of the pipeline claim that most of this could be managed with the right regulations and maintenance. Other pipelines have been known for success, although this one is quite bigger and has a larger impact on the environment. A problem that has been brought up to congress is clim ate change. With so much heat needed to separate the oil from the sand, there is about 17 percent more carbon dioxide being emitted into the atmosphere. Canada
