In this second of three podcasts on the theme of activism, Barbara and David are joined by three guests: Merlin Matthews, a lifelong activist and social entrepreneur, whose reputation as ‘Dr Bike’ at the London School of Economics grew into a pioneering inter-sectional charity called Re-Cycle, addressing both ecology and poverty; Blue Sandford, who is still only 18, but is already well known as a founding ‘youth’ member of Extinction Rebellion, a best-selling author, and a literally-underground protestor against over-development; and Wendelien Bellinger, a seasoned Montessorian, academic lecturer, and now Board Member at Montessori Europe.
