In this week’s Regional Roundup, we revisit the award-winning series “Loved to Death,” which explores the complex relationship between tourism and the environment. Local communities are struggling to preserve natural landscapes while keeping their economies afloat. The series looks at the impact of social media influencers on local trails, a timed-entry system at Rocky Mountain National Park aimed at controlling crowds, and a historic railroad’s switch from coal to oil-powered engines after a wildfire. It also examines the threat of invasive species carried in by visitors.
