On October 24, 2009, people in 181 countries came together to celebrate the International Day of Climate Action.  Over 5200 events took place around the world, many of them on college campuses in the U.S. and Canada.  My personal favorite (of those about which I read) was a spontaneous, yet coordinated event organized by the student group Bates Energy Action Movement at Bates College (ME).  See the video below. 

350.org's international campaign is dedicated to "building a movement to unite the world around solutions to the climate crisis" (http://www.350.org/mission), and I was impressed to see that Goshen College (IN) took it a step further and incorporated events related to sustainability.  They held an environmental and social justice coffee hour as part of their celebrations.

St. Lawrence University (NY) held a bike-walk-run, Allegheny College (PA) made a chandeleir out of 350 pieces of recyclable trash, Smith College (MA) made 350 origami cranes and rang its campus bell 350 times at 3:50pm, Concordia University (ON) held a recruitment effort to get 350 students to bike around Montreal, the University of British Columbia held a parade on the Cambie Bridge, and the University of Illnois held a climate change rally.  Let me just say, student never cease to amaze me.  They always come up with great ideas to create awareness and change on their campuses, across the country, and around the world.  Never doubt the capabilities of a student.
