A new national report finds access to nearby nature in the United States is deeply unequal. And that the gap is closely tied to race, income and pollution exposure. Researchers say the pattern shows up across the country, including in the Mountain West.

A new report shows tens of thousands of abandoned mines dot the U.S., including parts of the Mountain West. Experts say these sites pose pollution threats due to being in areas that are at high risk for flooding.

A new study led by the University of Michigan shows that large livestock farms are polluting the air across the U.S., including parts of the Mountain West. Researchers say these impacts are felt hardest by nearby communities, where people of color often live.

A new report shows the rate of spills from oil-and-gas drilling is dropping in some of the Mountain West’s top fossil fuel-producing states. But conservation groups warn these spills are still significant and can harm area waters, lands and wildlife.
