What do marine mammals tell us about the health of our oceans? The answer might surprise you—and it's more urgent than ever as climate change transforms our coastal environments.

Adam Ratner, Director of Conservation Engagement at The Marine Mammal Center, takes us behind the scenes of the world's largest marine mammal hospital as it celebrates its 50th anniversary. From rescuing seven marine mammals in 1975 to today's operation saving up to 1,000 animals annually, the Center has become a global leader in understanding how these magnificent creatures serve as sentinels for ocean health.

The conversation reveals concerning trends, including the discovery that 30% of rescued marine mammals experience human disturbance or harassment before rescue. Ratner explains the Center's recent response to 14 whale deaths in the San Francisco Bay Area in just weeks—many showing signs of malnutrition related to warming Arctic waters where gray whales feed. These deaths echo the 2019-2021 Unusual Mortality Event that saw gray whale populations drop by approximately 30%.

Yet amid these challenges, there are remarkable success stories. The Center's work with endangered Hawaiian monk seals has helped increase their population from about 1,000 to over 1,600, with approximately 30% of all living Hawaiian monk seals owing their lives to conservation interventions. Ratner also describes surprising opportunities for urban wildlife viewing, like harbor porpoises visible from the Golden Gate Bridge and humpback whales feeding within view of city skylines.

Whether you're a wildlife enthusiast, concerned about climate change, or simply curious about the ocean, this episode offers practical guidance on responsible wildlife viewing and ways anyon
