The Biden administration has appointed an Arizona woman to serve on its Environmental Justice Advisory Board.
Carletta Tilousi has been outspoken against uranium mining near the Grand Canyon area.
As a councilwoman for the Havasupai, she has carried on the work of her uncle, a former tribal chairman.
The tribe, which lives in a tributary of the Grand Canyon, has long considered uranium mining to be a threat to its water supply.
Tilousi has also been active in keeping Supai Village free of coronavirus during the pandemic.
The advisory board is expected to take up a variety of issues that affect communities of color, such as pollution, climate change and economic opportunity.
