Energy has always been human’s concern. Today, society handles different types of energies such as nuclear energy, solar energy, wind energy, gas energy, etc. The most dangerous energy that is used on daily basics is nuclear power. Nuclear power is a method of creating electricity through nuclear fission. “In a nuclear power plant, the fuel, an isotope of either uranium or plutonium, undergoes fission to produce the energy that is used to heat water and turn steam-driven turbine generators” (Christodouleas). Nuclear power is a dangerous way to harness energy and could also be described as an ill-advised way of using unclean power for the environment. The first nuclear power plant opened in Obninsk, Russia, in 1954, and since then, around, “435 operable civil nuclear reactors,” have opened around the world (Number of Nuclear Reactors Operable and under Construction). Clearly, nuclear power is spreading rapidly-creating nuclear waste. Society continues to debate over the use of nuclear power. Some people say that nuclear power is acceptable and should be expanded. However, others say that nuclear power has damaged the environment and harmed the population so it should be replaced by alternative sources of energy. Perhaps nuclear power creates energy in the short-term, but it is expensive and failure could have dire consequences for the population and the environment. The world should transition from nuclear power to other forms of energy because nuclear power is extremely unsafe for humanity and the planet, it is bad for environment, and it leaves thousands in poor health condition. First, Nuclear power is not safe to be built in crowded cities. Nuclear power has certainly made its mark on history. Perhaps the most well-known nuclear incident occurred on April 26, 1986, at Chernobyl. “Only 31 people were reported to have died, but because of the Soviet Union's policy of secrecy, we may never know the true cost” (Freeman). Many people were injured and thousands were born with abnormalities. As a result of this accident, thousands of people, mostly children, were diagnosed with thyroid cancer. “In 2000, about 2,000 cases of thyroid cancer had been reported in those exposed as children in the
