Every hero has an origin story. “I was 10 years old when the entire journey started,” explains Binish Desai. It began with a cartoon called Captain Planet, an animated TV series from the 1990s about an environmentalist with superpowers. Desai can still recite the show’s refrain: Captain Planet, he’s our hero / Gonna take pollution down to zero! “That tagline stuck in my mind,” he says. “I wanted to do something to help Captain Planet.”
