Urgent Vote Coming - Tell Congress to Defend the Clean Air Act Take action!
Make a difference in the challenge to confront global warming and prevent nuclear war and the development and use of nuclear weapons.
The Clean Air Act, our only regulatory tool to cut carbon emissions and prevent catastrophic climate change, is under attack. To protect our nation's health, we need your help!
Physicians for Social Responsibility is a non-profit advocacy organization that is the medical and public health voice for policies to prevent nuclear war and proliferation and to slow, stop and reverse global warming and toxic degradation of the environment. PSR's 32,400 medical and health professionals and concerned citizen members, 31 PSR chapters, over 60 Student PSR chapters at medical and public health schools, and over 25,000 e-activists, along with national and chapter board members and staff, form a unique nationwide network committed to a safe and healthy world.
Founded in 1961, PSR led the campaign to end atmospheric nuclear testing by documenting the presence of Strontium 90, a byproduct of atomic testing, in children's teeth. During the following two decades, PSR's work to educate the public about the dangers of nuclear war grew into an international movement with the founding of International Physicians for the Prevention of Nuclear War. In 1985, PSR shared the Nobel Peace Prize awarded to IPPNW for building public awareness and pressure to end the nuclear arms race.
During the 1990's, PSR built on this record of achievement by helping to end new nuclear warhead production and winning an international moratorium on explosive nuclear testing. A Comprehensive Nuclear Test Ban Treaty has been negotiated and signed, but has not been ratified by the United States Senate and has not yet come into force. PSR continues to educate and mobilize the health community and concerned citizens on a multitude of nuclear issues.
Understanding that nuclear war continues to be the most acute threat to human life and the global biosphere, PSR continues its commitment of 45 years to the elimination of nuclear weapons. As steps toward that goal, PSR adovcates for deep cuts in nuclear arsenals, taking nuclear weapons of hair-trigger alert, and ratification of the Comprhensive Nuclear Test Ban Treaty. PSR supports alternative strategies for conflict resolution, including increased diplomacy and the rule of law. To reduce the risk of nuclear proliferation and enhance public safety, PSR opposes nuclear power.
In 1992, recognizing that new dangers now threaten of our own and communities around the world, PSR expanded its mission to include environmental health, addressing issues such as global climate change, proliferation of toxics, and pollution. PSR's mobilization of the medical community on environmental health issues led to a collaboration among MIT, the Harvard School of Public Health, Brown University and PSR's Greater Boston chapter that resulted in Critical Condition, Dr. Eric Chivian's definitive volume on human health and the environment. Since then, PSR has brought the medical and public health perspective to advance environmental health and protect today's and future generations from the health effects of global warming and toxic degradation of the environment, and promoting renewable energy solutions and energy security.
On both the nuclear disarmament and environmental health fronts, PSR works for national priorities to ensure our nation's health, social and economic needs.
Please see PSR Accomplishments for details on the results we have achieved, together with our networks, to ensure a safe and healthy world.

How does a 'model nuclear project' go from done deal to dead-on-arrival? This timeline explores how the South Texas project, once hailed as the leader of the 'nuclear renaissance' was injured by skyrocketing costs, secrets, and scandal. Read more »
PSR has joined with the American Public Health Association, the Association of Public Health Laboratories, the National Association of County and City Health Officials, the National Environmental Health Association, and Trust for America’s Health to send a letter to U.S. Senators opposing Murkowski’s resolution. The January 19, 2010, letter affirmed that global warming will have grave public health consequences, citing the “increased likelihood of more frequent and intense heat waves, more wildfires, degraded air quality, more flooding, increased drought, more intense storms, harm to water resources and harm to agriculture.” Read more »
Nearly twenty years after the Cold War has ended, humankind is still faced with the genuine risk of instant extinction without representation. Even worse, this possibility could occur by accident, as a single computer miscalculation or mechanical error could lead to a civilization-ending nuclear war. The 9/11 attacks killed some 3,000 people causing enormous destruction, chaos, and grief. In comparison, a purposeful or accidental nuclear war between the U.S. and Russia would unquestionably kill tens of millions in the short-term, and untold millions in the long-term. Therefore, the threat of nuclear war is the most serious potential health, environmental, agricultural, educational and moral problem facing the human race. Read more »
