Kevin Brehm, Associate at Rocky Mountain Institute, will present "Reinventing Fire: An Introduction to RMI" at the next Politics of Sustainability Lecture for Tomorrow's Voices.

Kevin joined RMI from the University of Colorado MBA program, where he focused on finance and sustainability while leading his peers as a class president. Kevin entered business school as an experienced educator, having facilitated learning as a classroom teacher and outdoor educator. From 2007 to 2009 Kevin served in the inaugural Denver Teach for America corps, during which time he taught secondary science and geography classes while collaborating on school and district-wide curriculum development teams.

Christmas Bird Count

Aspen Center for Environmental Studies invites you to help count birds in the Aspen area during the Audubon Christmas Bird Count, the longest-running citizen science survey in the world. Birders of all experience levels are welcome and encouraged to participate in this important census that has helped assess the health of bird populations and guided conservation action since 1900. Across the Western Hemisphere, over 50,000 people count birds during local count events, many making the adventure of winter birding a seasonal tradition. Other ways to participate, in addition to the count day, are: feeder watching, owling, and count-week observations. Get into the swing of local winter birding at our Birding with ACES class on December 2nd and the first Tuesday of the month throughout the winter season. We hope you'll join ACES birding guide Rebecca Weiss for this important citizen science event!
