Here’s the chart of various mass extinction events to date, as a side note:
This chart is a bit different than what 60 Minutes used, where they argued (it’s in the video) that we’re through five and starting the sixth.
Now, I realize we live in a massively-polarized time, and 60 Minutes is generally insanely liberal, and so many people discount its stuff as “libs.” It’s similar to New York Times, etc.
That’s definitely one problem with why people don’t really pay attention to this stuff.
The bigger problem, of course, is that we’re all going to die, and probably within 80–90 years of now, and within that time frame, things don’t seem so bad…
