The Havasupai Tribe depends on the blue-green waters that emerge in the Grand Canyon for drinking water. But now, uranium mining on the canyon’s rims threatens the tribe’s existence and its way of life. A 20-year ban on new uranium mining claims around the Grand Canyon is at risk of being overturned by the Trump administration. The Grand Canyon is an irreplaceable natural treasure that draws over 5.5 million visitors to the park each year. Yet, irresponsibly operated uranium mines located on federal public land just miles from the North and South Rims threaten to permanently pollute the Grand Canyon landscape and the greater Colorado River.
