    Second year Xiye Bastida, from San Pedro Tultepec, Mexico, has participated in Greta Thunberg’s Fridays for the Future movement. She and friends began the Re-Earth Initiative aimed at “reimaging the future, reconnecting with the planet, and redefining collaboration.” Despite six years of environmental activism under her belt, Bastida says she’s just getting started.
