Hannah Ritchie, 30, was born in Falkirk and studied environmental sciences at Edinburgh. She is now head of research at Our World in Data, whose mission, according to Ritchie, is “to present data that helps us understand the world’s largest problems and how to solve them – that’s everything from the environmental metrics that I tend to cover to poverty, health, democracy and war”. Ritchie, who lives in London, is also a senior researcher at Oxford University. Not the End of the World – described by Margaret Atwood as “an inspiring data-mine which gives us not only real guidance, but the most necessary ingredient of all: hope” – is her first book.
You write that “I used to be convinced that I didn’t have a future left to live for”. What changed?
I grew up with climate change. I don’t really remember a time when it wasn’t talked about, so I became obsessed with it – a big part of my life was worrying about it. Then I went to university and that was all I was studying. The environmental metrics were getting worse and worse. I was also assuming that extreme poverty and hunger must be getting worse. This fed into the notion that humans were incapable of solving problems. A key turning point was discovering the work of [Swedish physician and academic] Hans Rosling. He did these Ted Talks, mainly focusing on human metrics, where he would show how the world was changing, through data. And it turned out that most of the human wellbeing metrics that I’d assumed to be getting worse were actually getting better. Take child mortality: 200 years ago, almost half of children would die before reaching puberty, and that’s now less than 5%. Now, the world is still terrible, and we have a lot of progress to make. But the realisation I came to was that we have the opportunity to improve both of these things at the same time: we can continue human progress while addressing our environmental problems.
