We can observe past pandemics and past meteor impacts. But we can also observe current and future meteors, predict their trajectories, and see if they’re going to be a threat. We can’t really do this with pandemic.
ie with meteors, we can use the past events and the present observations to predict the future; for pandemics, we can only use past events (to a large extent).
Why does the table indicate that we haven’t observed pandemics the same way we’ve observed wars, famines, and earth impactors?
