The anti-nuclear movement is a social and political campaign that opposes the use of nuclear energy and weapons. It emerged in the mid-20th century, particularly after events like the Hiroshima and Nagasaki bombings during World War II, which raised public awareness about the dangers of nuclear technology. Activists argue that nuclear power poses risks of accidents, radioactive waste, and potential nuclear proliferation. The movement has led to protests, advocacy for alternative energy sources, and calls for disarmament. Organizations such as Greenpeace and the Nuclear Information and Resource Service have played significant roles in promoting awareness and influencing policy regarding nuclear issues.
