Recommended: Effects of using fossil fuels on our environment
About eighty-five percent of our fuel comes from fossil fuels, which primary uses are electricity and fuel for cars. www.ucsusa.org. According to the Union of Concerned Scientists, “Many of the environmental problems our country faces today result from our fossil fuel dependence. These impacts include global warming, air quality deterioration, oil spills, and acid rain.” Other issues such as National Security issues, protection of foreign oil sources and the reliance we have on those foreign sources. Not to mention the billions of dollars spent protecting those interests. There are other energy sources, but are they any safer? Will humanity be better off to focus its attention on conserving what we have and using all resources we already have frugally with safety in mind first? The small amount of energy produced by means other than fossil fuels bring with them other questions as well as safety issues, is addressing those issues worth more than the efforts of conserving what fuel we have? “A nuclear reactor operates somewhat like a furnace. However, instead of using such fossil fuels as coal or oil, almost all reactors use uranium. And instead of burning in the reactor, the uranium fissions—that is, its nuclei split into two or more fragments. As a nucleus splits, it releases energy that is converted largely into heat. The fission of 1 pound of uranium releases more energy than the burning of 3 million pounds (1,500 tons) of coal. Stated in metric terms, the fission of 1 kilogram of uranium releases more energy than the burning of 3 million kilograms (3,000 metric tons) of coal.” “Unlike fossil-fuel plants, nuclear plants do not release solid or chemical pollutants into the atmosphere.” Corradini, 2012 One can certainly see the... ... middle of paper ... ....

The engineers in Visit Sunny Chernobyl created a new frontier past the safety zone because they want to test the limits of the reactor. What the scientists didn’t account for is that fact that the reactors already had the potential of a dangerous chain reaction. (Blackwell 6) Consequently, their boundary destroying led to catastrophic consequences and the total annihilation of a land area because of massive radiation. Blackwell thought Chernobyl was so horrific he expressed that no one should visit without a “working understanding of radiation and how it’s measured” (Blackwell 7). These are some horrific consequences that followed from surpassing the

The Three Mile Island accident took place in Middletown, Pennsylvania, on March 28, 1979. During this accident even though there was no meltdown, there was some radioactive gas that was let out into the air. As a result more than 50,000 people were evacuated from their homes (Levine 60-3). The Three Mile Island incident had a major impact on public opinion, the construction of nuclear plants, and the future of nuclear power.
On April 26th, 1986, operators at the Chernobyl Power Plant in Chernobyl, Ukraine, ran what they thought to be a routine safety test. But fate was not on the side of these operators. Without warning, reactor #4 became unstable, as it had been operating at a low power for a possible shutdown and the reactor’s design caused it to be unsafe at this level of power. Internal temperatures rose. Attempts to cool the system produced the opposite effect. Instantly, the nuclear core surged with power. At 1:23 p.m., the reactor exploded. The first blast ripped off the reactor's steel roof. The second blast released a large plume of radiation into the sky. Flames engulfed the building. For ten long days, fire fighters and power plant workers attempted to overcome the inferno. Thirty-one of them died of radiation poisoning. Chernobyl was the worst nuclear disaster in history. It unleashed radiation hundreds of times greater than the atomic bombs exploded over Japan during World War II. [1]
Because fossil fuels will still be around years from now, and there is no immediate threat to our current lifestyle, does that mean we, as humans, will continue to rely on fossil fuels in the future? If we decline to change our values and ideas, the answer is yes.
A - Plan of Investigation- For my Historical Investigation, I wanted to research the catastrophic nuclear meltdown that occurred on April 26th, 1986 at the Chernobyl Nuclear Power Plant in Ukraine. My research question is: Could the Chernobyl disaster have been avoided, if so, which moments in the chain of events leading to the accident needed to occur differently? To carry out my investigation, I plan on utilizing the Internet, encyclopedias and finding books that explain how accidental Chernobyl really was, the variety of mistakes made by the Ukrainians, as well as the Soviets, and how these problems could be fixed in accordance to the time period. I will use Chernobyl, global environmental injustice and mutagenic threats by Nicholas Low and Life Exposed: Biological Citizens after Chernobyl by Adriana Petryna for references that can help me in my investigation.

Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.

On April 26th 1986, the world’s worst nuclear accident occurred at the Chernobyl Nuclear Power Plant in Ukraine. The explosion sent a ‘cloud of radiation’ throughout the area, including Belarus, and much of the western Soviet Union and Europe, releasing 400 times more than the atomic bombing of Hiroshima. This is because a nuclear power plant contains a lot more nuclear material than an atomic bomb.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
On April26, 1986, the nuclear power plant was exploded in Chernobyl, Ukraine. At 1:23 AM, while everyone were sleeping, Reactor #4 exploded, and 40 hours later, all the city residence were forcefully moved to other cities, and they never return to their home. The Chernobyl disaster is ranked the worst nuclear accident. The Chernobyl nuclear power plant was ran by the Soviet Union central nuclear energy corporation. (International Atomic Energy Agency-IAEA, 2005)
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
