Physicians for Social Responsibility

Physicians for Social Responsibility (PSR) is the largest physician-led organization in the US working to protect the public from the threats of nuclear proliferation, climate change, and environmental toxins. Continuing its long history of physician-led activism, PSR produces and disseminates its own publications, provides specialized training, offers written and oral testimony to congress, conducts media interviews, and delivers professional and public education. PSR’s 50,000 members and e-activists, 30 state and local chapters, 39 student chapters, and 14 national staff form a nationwide network that target what they consider threats to global survival, specifically nuclear warfare, nuclear proliferation, global warming, and toxic degradation of the environment.
