Welcome to Greater Boston PSR:

We are a group of over 1,300 health professionals and community members in Massachusetts whose mission is to raise public awareness about the two existential threats to human health: nuclear war and climate change.


  • To inform the public and policy makers of the human health impacts of climate change and nuclear weapons
  • To promote local, state and federal action on these issues
  • To build coalitions with like minded groups to amplify this message


Change for Good
