Hot on the heels of the recent Low Impact Development Symposium at the Loews Hotel, Philly will host another flock of transformative thinkers the end of next month.

Cities Alive, the 9th annual Green Roof & Wall Conference, is coming to the City of Brotherly Love November 29-December 3, 2011.

This international event is co-hosted by Green Roofs for Healthy Cities, the City of Philadelphia Office of Sustainability, and the Pennsylvania Horticultural Society.

Why here, you ask? Check out the video from our friends at PHS for a few of the answers. All in all, we’d say this is just one more indication that Philadelphia is at the leading edge of the sustainability curve.
