Blue Sphere Foundation has become Only One

In 2019, the Blue Sphere Foundation, founded by Shawn Heinrichs, joined forces with SeaLegacy, founded by Cristina Mittermeier and Paul Nicklen, and they now work together to forge the next exciting chapter for SeaLegacy.

In 2020, SeaLegacy became part of the Only One Collective, a powerful new organization harnessing the power of storytelling, collective action, and crowdfunding to rebuild ocean life in this generation, for people and nature.

Its inaugural project is the Only One Platform, which you’re visiting now. Enjoy, and reach out anytime with questions at [email protected].
