In this story we hear from Dr Munro Stewart, a GP in Dundee. He works in a busy medical practice which covers a mixture of areas, some with serious deprivation and some more affluent. We walked around a few of Dundee’s parks and green spaces and talked about how improving public health and looking after our environment are remarkably similar. As Munro sees it, the biggest health crisis we are facing is climate change, and the future of public health is contingent on tackling climate related issues, and making healthcare sustainable enough that we can continue to provide it in the future. Topics covered include air pollution, active travel, diet, food prices, and flooding.
