The Swimmer & Thank Yous

Emeric Payer

I grew up in Hong Kong and spent most of my life in and around the water here. Swimming a full lap of the island was a personal goal I wanted to try, and pairing it with Fondation Tara Océan and Ocean Recovery Alliance was a straightforward way to support two teams doing real work for the ocean.
