‘Not much time left’: Salt Lake City’s mayor on the Great Lake drying up

Former environmental activist Erin Mendenhall leads a fast-growing city threatened by toxic dust from the lake's shrinking water levels

Erin Mendenhall was once an environmental activist, campaigning for clean air. Now, in a fitting but grim twist, she is the mayor of a fast-growing US city that faces being enveloped by a huge toxic cloud of dust.

Mendenhall, who is 42, became animated by the issue of air pollution after learning that the air quality in Salt Lake City had become so bad from cars, trucks and industry that it could take two years off the life of her newborn son. In 2010, she co-founded a non-profit group, called Breathe Utah, before embarking upon a political career that saw her become Salt Lake City's mayor in 2020. I had to do something [about the air pollution] or move," she says.
