There’s not a ton of room for environmental optimism these days—optimism in general seems to have taken a leave of absence in the Trump age—but that wasn’t the case at the 6th annual Climate Justice Youth Summit (CJYS), hosted by UPROSE, a Latino community-based organization based in Sunset Park, Brooklyn. The summit billed itself as “the largest gathering of young people of color discussing the future of climate change in the country,” and around midday, hundreds of attendees aged six to 18 cheerfully packed tight into a light-filled chapel in Morningside Heights’ Union Theological Seminary for one of the day’s highlights: a fashion show.
