“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has,” anthropologist Margaret Mead said. The Western North Carolina Green Building Council — its founders and its members — demonstrates the truth in those words. The council started as a conversation between two people, a decade ago. It then grew into a group of several people, but the goal remained the same: how to increase green building in the region. This Thursday, April 28, the council celebrates with its annual party (see below).
