Transition towns is a grassroots movement of individuals and community groups that encourages action at the local and regional level to future-proof our towns and cities by reducing our dependence on fossil fuels.  It is a positive response to the doom and gloom scenarios of post-peak oil and global warming.  It encourages individuals to work  with others co-operatively to develop the life skills and activities that will help us to live well in a post-carbon world.

These two video clips give an introduction.  The first is by Jo Duffs as a member of the Sustainable Hawkes Bay Trust and the second is by Rob Hopkins, founder of the Transition movement.
