I'm so proud of the work of the global conservation team at @montereybayaquarium.org. This mangrove restoration project in the Philippines is just one example of the ways they work to protect ocean health and strengthen fishing communities. www.panaynews.net/mangrove-nur... #SustainableSeafood

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

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

That's not all. Recently published studies on #PlasticChemicals show that of the 16,000 individual chemicals found in plastics, there are more than 4,200 ‘chemicals of concern’ that do not naturally break down in the environment, for example, or that are #toxic.

What does the #science say about how plastic affects climate? In three ways: (1) emission of greenhouse gases, (2) impacts on organisms that store carbon, and (3) radiative effects, altering how the planet reflects sunlight, absorbs heat, and traps warmth. www.plasticsandclimate.com/publications
