Episode Details

Writer, astronomer, and Carnegie Mellon University researcher Diane Turnshek has been encouraging cities to address light pollution for decades — and Pittsburgh finally caught on. Today, she talks about the new city ordinance she helped create, what it’ll take to replace 40,000 streetlights in Pittsburgh, and how much humans have in common with birds, bats, and the springtime flora we love most.

And don’t forget to set your alarm for 8:30 p.m. on Saturday to participate in Earth Hour, where people across the globe turn off their lights as a symbol of solidarity — and a catalyst for change — to benefit both people and the planet.
