Peter Lipman and Ben Brangwyn, co-founders of Transition Network with Rob Hopkins, will talk about - and answer questions about - transition's current developments, opportunities and issues from both a UK and global perspective. Transition is taking different forms in different national locales, and there are lessons to be learnt from their successes and failures. In addition, they'll look at the social, political and ecological angles of our current predicaments and talk about specific groups, activities and projects that are rising to the challenge.
