Sequoias of the Sea is a visually stunning and deeply human documentary about the collapse of Northern California’s kelp forests. Through the voices of scientists, divers, Tribal leaders, and fishermen, the film tells a story of loss, resilience, and hope along our coast.⁠

This month, the theme is ‘Life is Better in Color,’ and the color in corals actually comes from their little microscopic algae buddies, called zooxanthellae.⁠
⁠
These algae convert sunlight into energy through photosynthesis, which in turn feeds the coral and makes the coral reef a vibrant spectacle. In return, the coral provides a safe home and the nutrients the algae need to survive.⁠
⁠
Why is color important? Because when ocean temperatures rise, this partnership breaks down. The algae leave, and the coral turns white in a process called coral bleaching. It’s a signal of stress, but not always the end. With cooler waters and healthy conditions, corals can recover. ⁠
⁠
However, we have recently reached a pivotal climate tipping point, and many coral reefs around the world have experienced such high temperatures that they have not been able to recover. We are in danger of losing these ecosystems as we know them if we don’t act fast. ⁠
⁠
This month, we ask you to:⁠
🔹 Boycott all unnecessary purchases⁠ (Let’s go beyond November!)⁠
🔹 Share with #LifeIsBetterInColor #HopeForCoral #ForCoral⁠
🔹 Visit the coral bleaching link in our bio for tools and steps you can take⁠
