By the end of the 1970's, the movement against the use of nuclear power had spread globally, with groups in Germany and other parts of Europe coming together to protest the opening of nuclear power plants. Before the highly publicized accidents at Three Mile Island and Chernobyl brought to the forefront the question of plant safety, the primary concern was that the very existence of nuclear power threatened the future of the world. In 1978, a protest was organized in New York City near the United Nations at a time when the United States was in talks to pass the Nuclear Non-Proliferation Act. The poster for the event featured an illustration of the globe at the center of a mushroom cloud with the title, "Evacuation Would Be Impossible." Though nuclear weapons have not been used since 1945, nuclear accidents as recent as the Fukushima disaster in 2011 have continued to raise concerns about the threat nuclear power poses to the environment and to the future of political relations worldwide.
