How A Small English Town Spurred The Group That's Reshaping Global Climate Protests

Katerina Hasapopoulos is not your typical rule-breaker. She's 41, the daughter of immigrants and once a power-lunching marketing director.

Now, she says, "I'm a rebel. I'm a tree sister. I am an Earth protector."

Having children, three little girls, she says, helped her think more seriously about the world they would grow up in. Though Brexit dominates most headlines in the United Kingdom, Hasapopoulos devours stories about how humans are causing climate change.

"Whole businesses have been built on trashing our Earth — the very thing that feeds us, that gives us air," she says. "Many scientists are telling us that we are already in the sixth mass extinction."

So, last year, she joined her local environmental group in Stroud, a bohemian town of activists tucked into the rolling hills and — and it plans to continue mobilizing for the next two weeks.
