In the History of the United States there have been many changes that have occurred socially, politically and economically. However, the anti-nuclear movement was one of the most significant and important movements for social change in which the way we look at and utilize the generation of nuclear power. Nuclear power has been a problem in the US ever since the United States detonated the world's first atomic device. The bomb was exploded at the Trinity test site near Alamogordo, New Mexico on July 16, 1945. The movements roots are found in the Ban-the-Bomb era of the 60’s and before when the public became concerned about fallout from nuclear weapons testings from around 1954. After over 200,000 people were killed in Hiroshima and Nagasaki most people became instantly frightened with nuclear power and it sparked a strong beginning of the anti nuclear movement. Nuclear energy has no place in a safe, clean, sustainable future, it's both dangerous and expensive, just because nuclear pollution is invisible doesn't mean it's clean. Renewable energy is better for the environment and our economy. One million people demonstrated in New York City's Central Park against nuclear weapons and for an end to the cold war arms race. It was the largest anti-nuclear protest and the largest political demonstration in American history. After trying so hard for so many years opposing nuclear power, nuclear weapons, and uranium mining, there are thirty countries in which nuclear power plants operate, and only France, Hungary, Slovakia and Ukraine use them as the source for a majority of their electricity, although many other countries have a significant nuclear power generation capacity. Thorium, solar power, natural gas, and Hydrogen are four clean-energy alternatives for Uranium. We must all implement these forms of energy to cut back all the harmful uses of nuclear power.
