We are currently in the midst of one of the worst pandemics of this generation, but it is important to remember that there are also many non-biological catastrophes that nature can throw at us and that a large reason that our global population has grown so large so fast (now approaching 8 billion) is that Earth has been relatively quiet for the past two centuries.
