MASE MembersMASE Vision

The Multicultural Alliance for a Safe Environment envisions respectful, peaceful communities cherishing a healthy environment.

MASE Mission

MASE is rooted in the experiences of uranium-impacted communities of the southwestern U.S.  We are communities working to restore and protect the natural and cultural environment through respectfully promoting intercultural engagement among communities and institutions for the benefit of all life and future generations.

MASE works by

  • Developing and strengthening the relationships among the people of this community and region.
  • Understanding the complex and rich ecosystem that sustains and includes us.
  • Initiating and supporting sustainable ways of working and living that promote the health and well-being among the people and the environment
  • Engaging with government and industry to re-mediate and stop harm to our people and the environment.
