On this edition of People Fixing The World we meet people who’ve helped overcome long-standing cultural biases to create better outcomes for everyone. In India we hear about the social media campaigns which have helped city dwellers in Bengaluru see those who pick waste from rubbish dumps not as dangerous and dirty but as invaluable recyclers. In Nigeria we meet a traditional healer and a health worker who are collaborating to help improve the treatment of psychosis and break down some of the unhelpful attitudes towards severe mental health problems.
