The arguments for selling off public lands range from generating money from drilling to building housing – but it actually might be more cost effective to leave these spaces alone. Kyle Manley is a postdoctoral researcher at the University of Colorado Boulder’s Earth Lab. He joins host Krys Boyd to make the case for leaving public lands as-is, why plans for affordable housing are unrealistic and how we can put a dollar value on ecological impact. His article “The true worth of America’s public lands” was published in Scientific American.
