If you've been feeling down about the state of the global environment, particularly after COP26 in Glasgow, this episode is for you. I'm sharing a presentation I delivered to around 200 doctors last month at the Doctors for the Environment iDEA 2021 conference. I was invited by Dr Kate Wylie to share a message of innovation and progress so conference attendees could leave the conference with a feeling of hope. I hope the presentation has a similar impact on you too.
