One of the problems with climate change is that it is a global, or planetary issue. Our major form of political organization currently is nationalism which is too small to establish a global response as the tragedy of the commons is almost ensured to occur short of some massive leap in human morality. – Cam Riley

Sustainability, particularly in the form of compact urbanism with bright green innovation, concentrates human interactions with each other and networked systems, making it easier to suffuse daily life with the sort of intelligence that allows data to be gathered, shared and connected. The Net and the public square, as Castells wrote, are symbiants. – Alex Steffen
