Nuclear Energy and Safety Concerns

The video covers nuclear energy, focusing on its use as an electricity source and its environmental effects. It explains nuclear fission, radioactivity, and the process of generating electricity using nuclear power. Safety measures in nuclear power plants are discussed, along with the environmental impacts of nuclear energy, including its non-renewable nature and lack of air pollutants during electricity generation. The video also highlights historical nuclear meltdowns and their consequences.
