🧔🏻 William McGregor

A big, gentle Scotsman who believes you don't have to fix the whole planet — you just have to help the folk already trying.

🐧 Escobar

A small, brave Adélie penguin with a very loud HONK. Whenever an animal's too scared to try something new, Escobar goes first.

🚐 Thistle

The electric van that runs on sunshine. Green on the bottom, white on top, with a wee thistle on her side. Quiet as a cat.

the best bit

Every adventure really happened

Escobar's adventures are made-up, but the world he's helping is real. Behind every story is a true tale of beavers, wolves, tortoises, coral and clean energy — and the real scientists and communities bringing nature back.
