This is how you rebuild an ecosystem: one teeny tiny oyster at a time. 🦪⁠
⁠
And did you know, you can fit 15 million oyster larvae into the palm of your hand!? ⁠
⁠
Expedition diver explains to how the Project takes those tiny larvae, plops them in tanks of seawater, and waits for them to attach to the reef balls. Once an oyster attaches, it's pretty happy to stay there, for the rest of its life. ⁠
⁠
Happy as a clam... ❣️⁠

Did you know New York was built on oysters? 🦪

Acres and acres of them. They made the city a centre of trade, and the Lenape, who called Manhattan 'Manahatta', were avid oyster eaters long before that.

Their shells were melted down into lime, which went into the city’s buildings and streets. Even below the base of the Statue of Liberty is made of oysters!

Going to the pub might be climate's version of Parkrun?⁠
⁠
Here's the theory: nobody signs up to run a marathon in Helsinki. But you see a Parkrun happening in your own neighbourhood, and one day you think, "I could probably do that."⁠
⁠
tells that climate action works the same way. It's not the big, distant asks that move people, it's seeing something happening locally, something low-stakes and familiar, that makes you think "I could join in with that."⁠
