Dr Lachlan McIver has found himself fighting for the lives of his patients all over the world: from a remote medical clinic, where a headlamp normally used to avoid snakes provided the light for a surgery, to the biggest cities, where he advocates for action about the health impacts of climate change.

Lachlan is the tropical diseases and planetary health advisor at Médecins Sans Frontières, and in the Drawing Room, he shares his expertise and the remarkable moments of community and survival he's seen throughout his career.
