In 2025, the San Francisco Bay witnessed a heartbreaking surge in gray whale deaths, with 21 fatalities—the highest in a quarter-century—largely due to vessel strikes. With only about 13,000 whales left, the population is at its lowest since the 1970s.

The Marine Mammal Protection Act was enacted in 1972 to safeguard marine mammals like gray whales, which rebounded from near extinction to about 26,000 by the 1990s. However, a concerning rise in gray whale deaths, with 21 reported in 2025, highlights ongoing threats from climate change and vessel traffic, leading to a current population of approximately 13,000 and raising urgent conservation concerns.
