Listening to photographer Ed Burtynsky's Ted speech revealed a fantastic blog called World Changing, which is an amazing collection of articles, tools, models and ideas for building a better future, all coming from contributors all around the world: "WorldChanging.com works from a simple premise: that the tools, models and ideas for building a better future lie all around us. That plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive, means and opportunity for profound positive change are already present. That another world is not just possible, it's here. We only need to put the pieces together."
