This week, we talk to entomologist and author Doug Tallamy, who wants people to landscape with native plants to feed bees and other pollinators. His goal is for half of the 40 million acres of lawn in the U.S. to be replanted with native species in what he calls the "Home Grown National Park." We'll also visit a special bog habitat in eastern Pennsylvania that was formed in the ice age. Plus, we join researchers at Presque Isle State Park who are looking for an invasive snail that has gained a foothold in Lake Erie. New research reveals how fireflies are faring in the eastern U.S.

We have news about the Allegheny County Clean Air Fund and a new training effort for energy efficiency jobs.
