“When discussing population, let your starting point be about finding the issues that you have in common. It could be about congestion, climate change, loss of heritage, the list goes on. It is not about us pushing our view of the world onto people. Instead it is about helping them to see population in a new light by showing how it connects to the issues that are important to them.” This article is based on Mark Allen's speech to the Victorian Branch of Sustainable Population Australia (SPA) Seminar: Attitudes and communication in population and the environment on 23 April 2016. Videos of the event will be available soon. Mark Allen started Population Permaculture and Planning. He has a background in town planning.
