Scientists are sounding the alarm after a record-breaking spike in grey whales washing up along the Pacific Coast. The U.S. National Oceanic & Atmospheric Administration (NOAA) reports that these numbers are the highest seen in decades, raising urgent questions about the health of our oceans. We sit down with Kyla Bennett, Director of Science Policy with Public Employees for Environmental Responsibility, to discuss the potential threats – from food shortages to changing ocean temperatures – and what this means for the future of the grey whale population.
