Dr Barry Davis has had a distinguished career as a physician and bio-statistician. His new book is titled, “The Preventioneers: Diseases, Disasters, and the Discoveries that Changed the World.” He makes the point that adopting a prevention mindset could reshape our response to climate change which follows the same pattern he’s seen in public health crises: early resistance, delayed action, and eventual reckoning. We need to overcome our human tendency to delay action until disaster strikes he says.
