We often hear about projects that will harm salmon such as the recently  proposed gold and copper mine in Alaska, but why does it matter? As it  turns out, salmon isn’t just a tasty meal, but a multi-billion dollar  economic engine, a centerpiece of Native American and Alaskan culture,  and a species that rivers, streams, and nearby ecosystems can’t survive  without. Today, we’ll break down four primary human threats endangering  salmon, and discuss a few ways to protect them in the future. With  special guest Dr. Syma Ebbin: Professor of Agricultural and Resource  Economics and the Connecticut Sea Grant Research Coordinator at the University of Connecticut.
