In 1985, architect Paul Pholeros was challenged by the director of an Aboriginal-controlled health service to "stop people getting sick" in a small indigenous community in south Australia. The key insights: think beyond medicine and fix the local environment. In this sparky, interactive talk, Pholeros describes projects undertaken by Healthabitat, the organization he now runs to help reduce poverty -- through practical design fixes -- in Australia and beyond.
