If you have the chance to get to the RGS on Saturday 20th of October, there is what sounds like a fascinating day.

INTERDEPENDENCE DAY
In a host of talks, workshops, music, film, art and games, Interdependence Day will explore what it means to live in an interdependent world. For anyone who cares about the earth and the people we share it with. The new and extraordinary challenges that lie before us at the start of the twenty-first century - creeping globalisation, climate change, seemingly unstoppable and impossible to fully comprehend - can appear beyond the control of any one person. Finding ways to take a fresh approach to the defining questions of our time are the inspiration for Interdependence Day 2007.
