A kite in the shape of a bird flies over the "People's Climate March" as people progress down 6th Ave. in the Manhattan borough of New York September 21, 2014. Organizers are expecting up to 100,000 to join the People's Climate March in midtown Manhattan ahead of this week's U.N. General Assembly, which brings together 120 world leaders to discuss reducing carbon emissions that threaten the environment.
