Watch this drone capture the immensity of the People’s Climate March

Hailed as the largest climate demonstration in history, the People’s Climate March is estimated to have drawn as many as 400,000 demonstrators to the streets of Manhattan yesterday. While organizers initially expected around 100,000 attendees, the crowd count hovered at around 310,000 by 3pm (the demonstrators—many sporting clever signs and witty costumes—had lined up hours before the 11:30am start time) and eventually spilled over into streets outside the official route.
