Even the deep ocean isn't immune to #PlasticPollution! And while a toy may appear innocent, the associated problems are not. That's why @montereybayaquarium.org supports legislation and international agreements that reduce unnecessary plastic at the source. bit.ly/3V4SNUu

While the fund doesn't directly support the Aquarium’s Sea Otter Program, it has raised $5 million since 2006 for other organizations whose work complements all that we’re doing to recover this iconic species. bit.ly/3Upflix #WildlifeConservation #MarineMammal #SeaOtter #ActForTheOcean

Huge thanks to @governor.ca.gov for signing into law a bill by State Sen. John Laird to re-establish California Sea Otter Voluntary Contribution Fund. The Fund will again appear on the 2026 state income tax return; to remain active, it must attract at least $250,000 in contributions each year.

The strength of conservation is measured not when it is easy, but when it is tested. Last week's changes to the U.S. Endangered Species Act regulations weaken protections that have helped recover some of America's most iconic wildlife. #EndangeredSpecies #WildlifeConservation

For more than 50 years, the ESA has been successful at preventing extinction because it protects habitat. This change sacrifices science-based management for industrial development.

Reopening the Pacific #OCS to drilling ignores everything we learned from #Deepwater Horizon, #Refugio, and #Cosco-Busan. It steers us backward toward the same risks that devastated communities, #wildlife, and coastal economies.
