Introduction
In this post, I argue that the scale of farmed animal suffering far exceeds the expected mortality risk from engineered pandemics—by a factor of at least 100. I haven’t seen this explicit comparison made elsewhere, yet it strongly affects my personal cause prioritization.
However, it's important not to update solely on scale: the tractability and neglectedness of pandemic preparedness may still justify prioritizing it, despite its seemingly smaller scale. I would be excited to see more detailed work in this area—for example, comparing the Disability-Adjusted Life Years (DALYs) lost to farming versus pandemics more rigorously than I do here.
Scale of biorisk
In The Precipice (2020), Toby Ord estimates a 1/30 risk of human extinction from engineered pandemics[1] this century. Spreading this risk over 80 years—from 2020 to 2100—gives an approximate 1/2,360 chance of extinction per year (on average).
The average global population in the 21st century [...]
