In a world so divided in so many ways, sustainable economic development on a global scale will amount to nothing but a figment of human imagination or, to put it mildly, just wishful thinking. Do you agree with this statement? What do you make of the many world summits on SD that have been held over the past two decades, the latest being the Rio+20 Earth Summit 2012 in Brazil?
