Biodiversity falls below ‘safe levels’ globally
This is indeed very depressing. A very excellent book about the scope of this problem is &quot;The Sixth Extinction&quot; [1]. One crazy anecdote from the book: the author explains how rare it should be to witness <i>any</i> extinction of a species within one&#x27;s lifetime. The average &quot;background&quot; rate of extinction is something like one per one thousand years. During the course of writing the book, the author <i>personally</i> witnessed something like five species go extinct. It some ways this is an incredible time to be alive, but in many it&#x27;s the most depressing time one could imagine... ever?<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Sixth_Extinction:_An_Unnatural_History" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;The_Sixth_Extinction:_An_Unnat...</a>
