Having recently finished listening to the 2008 Reith lectures, I thought it timely to add a post referring to last years series (which resonated with me fairly strongly). http://www.bbc.co.uk/radio4/reith2007
In this lecture series Professor Jeffrey Sachs outlines a concept called the Anthropocene - the tipping point. He outlines in his talk the current state of the world (politically, environmentally, developmentally, and technologically) and the problems we are facing, and must deal with, if we want to prevent the world from imploding in on itself.
