Growing up in a town stricken by both drought and floods, it didn't take Xiye Bastida long to understand the perils of climate change -- or to decide to do something about it.

Bastida was born and raised in San Pedro Tultepec, a small town southwest of Mexico City, and moved to the US after a three-year drought in her hometown was broken by devastating floods. She began her career as an environmentalist soon after. Now a climate justice activist based in New York City, she is one of the lead organizers of Fridays For Future, the youth climate strike movement founded by Greta Thunberg. She also sits on the administration committee of the People's Climate Movement, where she brings a voice to existing grassroots climate organizations.
