Kristen Marhaver: How we're helping baby corals grow

13:46 minutes · Filmed Oct 2015 · Posted Dec 2015 · Mission Blue II

Kristen Marhaver studies baby corals, tiny creatures the size of a poppyseed that, over slow and patient centuries, can grow to create structures hundreds of miles long: our coral reefs. As she admits, it's easy to get sad about the state of coral these days. So instead, she focuses on the wonder -- and in this talk, she tells us all about these amazing marine invertebrates and their mysterious lives.

Quote of the Week

No idea is born fully formed. It emerges a little bit as a child is born, kind of messy and confused, but full of possibilities. And it's only through generous contribution, faith and challenge that they achieve their potential."
