US political advocacy body on climate
Physicians for Social Responsibility (PSR) is a physician-led organization in the US working to protect the public from the threats of nuclear proliferation, climate change, and environmental toxins. It produces and disseminates publications, provides specialized training, offers written and oral testimony to congress, conducts media interviews, and delivers professional and public education. PSR's members and e-activists, state and local chapters, student chapters, and 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.[1]
