Tom Mustill is a conservation biologist and he makes beautiful films about where nature and people meet. He’s worked with Greta Thunberg and David Attenborough, he’s been shat on by bats in Mexico, and recently he finished a book called How to Speak Whale.  It describes the very real possibility that someday, maybe even in my lifetime, we’ll begin to understand the complex language of whales--and all this would imply.I interviewed Tom for hours and I didn't want him to stop until he’d told me every last thing he’s learned about whale behavior and every story he could remember. He was polite about it. I don’t know why I felt this insatiable need to hear every story. Maybe it seems that if we could understand whale culture a little bit, everything would make a little more sense? Anyway I recorded Tom for as long as he'd let me.
