In a few days we'll be putting out a conversation with Dr Greg Lewis, who studies how to prevent global catastrophic biological risks at Oxford's Future of Humanity Institute.

Greg also wrote a new problem profile on that topic for our website, and reading that is a good lead-in to our interview with him. So in a bit of an experiment we decided to make this audio version of that article, narrated by the producer of the 80,000 Hours Podcast, Keiran Harris.

We’re thinking about having audio versions of other important articles we write, so it’d be great if you could let us know if you’d like more of these. You can email us your view at podcast@80000hours.org.

If you want to check out all of Greg’s graphs and footnotes that we didn’t include, and get links to learn more about GCBRs - you can find those here.

And if you want to read more about COVID-19, the 80,000 Hours team has produced a fantastic package of 10 pieces about how to stop the pandemic. You can find those here.
