The People's Climate March on September 21 drew an incredible 310,000 protestors to the streets of New York, with tens of thousands of people taking part in action elsewhere on the planet.
The march was held ahead of Tuesday's U.N. Climate Summit, which will be the largest gathering of heads of state ever to discuss global warming.
The march drew people from as close as New York City to as far away as Europe and Africa, and a diverse array of interests were represented. But when Mashable spoke to participants, a number of consistent theme emerged -- such as the urgency of addressing the climate change issue, the desire to preserve the planet for future generations and the need for world leaders to take action at the Climate Summit, which starts on Tuesday.
