#160 – Hannah Ritchie on why it makes sense to be optimistic about the environment

"There's no money to invest in education elsewhere, so they almost get trapped in the cycle where they don't get a lot from crop production, but everyone in the family has to work there to just stay afloat. Basically, you get locked in. There's almost no opportunities externally to go elsewhere. So one of my core arguments is that if you're going to address global poverty, you have to increase agricultural productivity in sub-Saharan Africa. There's almost no way of avoiding that." — Hannah RitchieIn today’s episode, host Luisa Rodriguez interviews the head of research at Our World in Data — Hannah Ritchie — on the case for environmental optimism.Links to learn more, summary and full transcript.They cover:Why agricultural productivity in sub-Saharan Africa could be so important, and how much better things could getHer new book about how we could be the first generation to build a sustainable planetWhether climate change is the most worrying environmental issueHow we reduced outdoor air pollutionWhy Hannah is worried about the state of ​​biodiversitySolutions that address multiple environmental issues at onceHow the world coordinated to address the hole in the ozone layerSurprises from Our World in Data’s researchPsychological challenges that come up in Hannah’s workAnd plenty moreGet this episode by subscribing to our podcast on the world’s most pressing problems and how to solve them: type ‘80,000 Hours’ into your podcasting app. Or read the transcript.Producer and editor: Keiran HarrisAudio Engineering Lead: Ben CordellTechnical editing: Milo McGuire and Dominic ArmstrongAdditional content editing: Katy Moore and Luisa RodriguezTranscriptions: Katy Moore
