Climate change is refers to the rise in average surface temperatures on earth, mostly due to the burning of the fossil fuels such as oil and coal, which emits greenhouse gases into the atmosphere which are primarily carbon dioxide, water vapor, methane, nitrous oxide, and chlorofluorocarbons (#02). In addition, other human activities, such as agriculture and deforestation, also contribute to the growth of greenhouse gases that cause climate change (#01). According to this, many have make their own conclusions on how are humans responsible for climate change and whether or not it is a real thing. Some people think and guarantee that climate change is real and it is happening at least in part because of human activity. This people argue that in the last 100 years, carbon dioxide concentrations in the atmosphere have risen from 290 parts per million (ppm) to 369 ppm, with strong evidence pointing to the burning of fossil fuels by humans as a primary cause of these increases (#03).
In class, discussions were held about how humans can respond to climate change. One of the options was mitigation which means people will try to stop/prevent any further increases in global temperature. Mitigation options include consuming fewer fossil fuels and sequestering carbon. The documentary also pertains to coal. Coal is the most abundant fossil fuel.
Also Humans Pollution: Environment said, “The vast majority of energy comes from the burning of fossil fuels (oil, natural gas, and coal). The increased use of fossil fuels has a negative effect on the health of the environment in terms of air and water pollution. Air pollution from greater coal use and vehicle exhaust has led to acid rain, which is particularly damaging to forests, lakes, and streams.” Most of our energy comes from the burning of fossil fuels which may cause air pollution. The last piece of evidence from Humans Pollution: Environment is, “Rising fossil fuel use also means a greater build-up of carbon dioxide in the atmosphere, higher greenhouse gas emissions, and global warming. The environmental costs of using fossil fuels have led to efforts to decrease their level of use.
Deepwater Horizon Explosion and Oil Spill The incident occurred due to the uncontrolled release of pressure from the oil well and the failure of the pressure control system to contain the pressure, thus leading to an explosion. Following which, the oil rig sank on 22nd April 2010 and led to the largest oil spill in the history of petroleum industry. The risk of oil spill could have been reduced if BP had taken the appropriate measures; as reports have stated that BP were aware of the metal casing for the blowout preventer breaking down under high pressure and yet improper maintenance was done to preserve the functionality of the pressure control system. Environmental impact The oil spill posed detrimental effects on both the marine ecosystem as well as the lives of humans in the affected region. In total, approximately 4.9 million barrels of crude oil were spilled into the water, leading to the suffocation of marine life due to its toxicity.
The ocean acidification is probably the most important issue on our planet today. I think the ocean acidification is the most important issue today because ocean acidification affects all life on earth. For me, counter the ocean acidification needs to be a priority now because it was directly connected with the last few mass extension. If we succeed to stop the ocean acidification, we are going to resolve a lot of problems who are going to be linked with this issue. I’m sure the cause of the ocean acidification is that we are changing the environment very quickly and now, we are converting hundreds of millions of years of fossil fuel, burn it, and turn it into carbon dioxide.
With the development of temperature and pressure measurements, together with an understanding of the properties of gases, land desalination began to play an important role from the early 1950’s. The expansion of oil discoveries in the Arabian Gulf countries, USA, Caribbean Island, and a few others, where drinking water is rare, also affected desalination development. The first commercial land-based seawater desalination plant was installed by the Ottomans in Jeddah, Saudi Arabia. This crude distillation unit was a boiler working under atmospheric pressure, but this unit suffered from severe scale deposits and With the improvement in submerged-tube technology, the first evaporators with a total capacity in excess of 45,000 m3/d were built in Kuwait Curacao in the early
I believe that coal is bad for the earth, plants, animals and humans based on the information I have collected. Coal can hurt the earth and also cause air pollution. We have to find a way to make coal produced energy extinct. Coal and why it’s dirty: Coal… if tiny doses of these chemicals get into our drinking water we will most likely get really sick and/or die. Did you know that coal powers 39% of the world’s energy, and coal is the most used energy source!
Green house gases, such as carbon dioxide, are effecting a lot more than just our atmospheres air pollution and climate changes. This colorless, odorless chemical compound is vital to our life organisms on earth but since the Industrial Revolution has been significantly over produced “…due to the burning of fossil fuels and land use change.” (National Oceanic and Atmospheric Administration, year), which in return is harming our world in many different ways that we may have never even thought of. Specifically, this element is creating chemical changes in our oceans called ocean acidification (NOAA, year). Ocean acidification is becoming an increasingly substantial problem due to its hazardous effects to marine life and seawater which eventually
Refineries that turn crude oil into vehicle fuel add to pollution and use even more energy. There are alternative fuels, such as electricity. But these vehicles powered by electricity also have an environmental impact. Large amounts of electricity to charge all-electric cars originate from coal-burning power plants. This produces harmful carbon emissions, and also uses a nonrenewable fuel source to make electricity.
Power plants releases smoke and ash during processing of burning of coal contributed significantly to the problem of air pollution in the late 19th and early 20th centuries. In 1940 air pollution in the United States and the complaints of the public pressured the government to do something about the problem, the government regulators had to act. The smog that formed around Los Angeles and other big cities around began to report air quality degradation. California was the first state to pass air pollution regulations. In 1947 just shortly after California acted the government convened the first national air pollution symposium consisting of the environmental experts and the representatives of the government.
Sulfur dioxide and nitrogen oxide both can dissolve in water. I personally feel that it is because of humans acid rain is so harmful. Over the years humans have mixed and released so many some many different chemicals in the air. When power plants burn things like fossil fuels, like coal to get electricity they create and release more of sulfur dioxide and nitrogen oxide. Other that cause acid rain are things like cars, trucks and buses because they also release
The US is going to use some source of energy and that will always have some negative effects on the environment. The alternative sources for the energy we need have negative effects on the environment as well. “In 2011 U.S. coal-fired power plants emitted nearly two billion metric tons of greenhouse gases -- roughly eight times the amount produced by mining, refining and burning tar sands”(Biello). Canada is going to develop a pipeline system to export oil whether it’s to the US or other countries, like China, that are trying to get access to this resource. With the proposed Keystone XL pipeline there are many environmental and safety standards that would be enforced to ensure that concerns such as oil leaks are detected, fixed and cleaned up properly and quickly.
After watching the documentary, there is no doubt that natural gas drilling is destroying our environment. For instance, hydraulic fracturing produces large amounts of wastewater, which may contain dissolved chemicals and other contaminants that require treatment before disposal or reuse (EIA, 2014). Furthermore, the chemicals used in the process can contaminate surrounding areas if they are released by spills, leaks, faulty well construction, or other exposure
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.
The toxic chemicals released from extraction were poisoning clean water sources. This lead to increasing cases of cancer, hyperthyroidism, lupus, and renal failure in people located in areas near the present pipeline. These effects clearly show the vast hazard this oil presents for the environment and society. In conclusion, as stated and proven throughout this essay, the Keystone pipeline creates many environmental issues. The Keystone pipeline should not be built because it endangers the environment and has the ability to create catastrophic damages through pollution and habitat desecration.
