Groups say proposals to use fracked natural gas to produce hydrogen in Western Pennsylvania pose health and climate risks. An investigation in Ohio alleges that many people whose names are on public comments in favor of fracking in state parks say they did not submit them.
We’ll also hear from an author who revisited the Youghiogheny River of his youth to find some changes for the better. Plus, the federal government wants to put the salamander mussel on the endangered species list. We revisit a story that joins researchers surveying the Allegheny River for the mudpuppy salamander that’s critical for the mussel’s survival.
We have news about ticks, spotted lanternfly’s risk to Pennsylvania forests, and the hellbender salamander.
