Carbon dioxide is an asphyxiant with a density greater than air which leads it to accumulate in low or enclosed spaces, and asphyxiation fatalities will occur when there is a high concentration of CO2. In the room temperature, carbon dioxide is odourless and colourless which means that we are unable to smell or see it at the elevated concentrations. With the concentration of carbon dioxide, people will have headache and loss of consciousness, and inhale high density CO2 will cause death. Factors that could lead to leakage of carbon dioxide includes the damage to structures and equipment and improper maintenance of pipelines. Since there is a carbon dioxide compression process on site, the leakage is similar to a pressurised release and the leak of carbon dioxide is colder than the surrounding atmosphere (HSE, 2015).
The oil spill caused monumental environmental damage to the Alaskan coastline where some species are still recovering from today. The impact of the spill on flora and fauna, human life and the economy was staggering which was caused by human error, lack of adequate resources and insufficient support from external systems. The oil spill tested the preparedness and response to a disaster of this magnitude, which revealed many shortcomings. Due to this historical event, numerous important lessons and recommendations emerged to prevent or mitigate the impacts of future
Fracking uses dangerous chemicals, chemicals that are bad for one’s personal health at the same time, the health of the environment. There are a known 750 chemicals…. 26 of which are either likely or known carcinogens (Is Fracking A Good Idea? 12). Many chemicals that could be harmful to you are not just the ones they put into the ground, but some that come up from the ground can also harm you.
When inhaled it stops the oxygen that gets to the brain and can be life threatening. When natural gas builds up it causes explosions also. Many people use natural gas to heat their water, but there are many reports of the water being contaminated and making people sick and their animals sick due to natural gas water heaters exploding. If a water heater explodes it can contaminate many water supplies not just one, if in town the water will contaminate some if not all of the households and it could expand further out. Today fracking in the United States is very common and very helpful, fracking produces natural gas which is used to fuel vehicles, heat homes and businesses, and is also used to cook with, although natural gas has its perks it also is a tad bit dangerous if not consumed correctly.
Fracking is the process of breaking the rock with chemicals and water 3 to 7 miles underground, tearing up the land around the well, putting chemicals underground that can cause defects of crop growth, harming the environment. When done gathering the oils some companies dump unwanted fracking fluids back beneath the surface. This causes plants and the living things that are eating from them contaminated by the underground hydraulic chemicals. (Source 6) In 2010 there was a fracking explosion destroying a huge body of water. This caused a pressurized flow of oil through the Gulf of Mexico floor causing clean water with many plants an animals in it to become threatened by the chemicals.
Without it we would be dead from the dehydration. Fracking in this case can contaminate it to where we cannot drink it and if we do it can lead to death or a trip to the hospital: Drinking water sources have been contaminated with explosive methane, as well as other dangerous substances, such as benzene and arsenic, that can cause cancer and other serious illnesses. Toxic chemicals, as well as erosion and runoff from drilling operations, have fouled
While the quality of water is important for many individuals, wasting water in the matter they do can seem like a major crime. The Congressional Digest also says that fracking is a huge waste of water, and is one of the biggest wastes of water around. Millions of gallons of water are dumped into the soil to pop up these natural gases, and its no longer useful once it comes back. In fact the water that goes down into these holes, does come back up, however once it comes back up with the gas and oil, it is no longer the water we thought it was. The “flow back” or water that returns to the surface, does not always come back up,“…less than 30 percent to more than 70 percent of the original fracture fluid volume” is brought back up, and is rendered unusable (Congressional Digest).
Fracking is responsible for not only water quality but also for air quality since fracking frees some unhealthy chemicals to the air. Therefore, the ones who get the most negative effects are people who live gas drilling because the gas is taken by blowing off the water, sand, and chemical underground to destroy shale deposits. The Natural Resources Defense Council (NRDC) pointed out that the air polluted by fracking could causes several diseases, especially cancer.
Virus survived in the polluted water can invade into the body defense system through the drinking process. Heavy metals also cause some trouble. When people take water contains heavy metals, chronic intoxication, teratogenesis, and cancer may occur. Another problem is the lack of clear water supply. Water shortage is nothing new for the world.
Many people used tires. Thousands of tires were set on fire, and that hurt the environment. Hawler, the capital, has a halo of ashes, gas and other fuggy material around it if looked at outside the city. The waters of Kurdistan were also contaminated, as in the case of the Sirwan River, whose water is used for drinking, which eventually led to an uproar. There have been kidney problems, which led to the belief that the environment must be kept clean.
