Record Climate Change March in New York City Monday

The demonstrators, who included homeowners flooded by Hurricane Sandy, NYC political leaders and indigenous people fighting oil company developments on their lands, chanted, sang and danced to draw attention to the growing threat of climate change.

U.N. Secretary-General Ban Ki Moon, former U.S. vice president Al Gore, New York City Mayor Bill de Blasio, and actors Mark Ruffalo and Leonardo DiCaprio were among the demonstrators at the climate change march.

Ban Ki Moon announced just last week that DiCaprio was officially named a U.N. Messenger of Peace for his lifetime commitment to important environmental causes.

Of note, over 1,100 environmentally-focused organizations endorsed and.or participated in the climate change march, including well-known groups such as 350.org, Avaaz, the Sierra Club, Climate Justice Alliance and the Service Employees International Union.

Statements from climate change march participants

“I’m totally passionate about our planet and what’s happening with our life here,” said Heather Snow, 57, a massage therapist from Wilmington, N.C. who attended the climate change rally. “The whole Congress, everyone has gone insane, and it’s time to end the insanity. I don’t know how, I don’t know when, but it’s got to happen soon. We’re running out of time.”

Bill McKibben, the executive director of  350.org, commented: “we need to demonstrate there are an awful lot of people that care about climate change and demonstrate that this is a huge issue for all kinds of people. Since the fossil fuel companies have money, we have to have something on our side, and that’s people.”
