Funding asteroid detection is one way to reduce this risk. Newberry (2021) estimates that spending $1.2 billion to detect all remaining asteroids with a diameter greater than 10 kilometres would decrease the chance that we go extinct within the next hundred years by 1-in-300-billion. [...] Preventing future pandemics is another way to reduce the risk of premature human extinction. Drawing on Millet and Snyder-Beattie (2017), Greaves and MacAskill estimate that spending $250 billion strengthening our healthcare systems would reduce the risk of extinction within the next hundred years by about 1-in-2,200,000
