A reader alerted me to a video by Swedish academic Hans Rosling. It's called Population growth and climate change explained by Hans Rosling, and appears on The Guardian's Global Development page.
That banner should tell you everything you need to know. FYI, DOTE is not supported by the Bill & Melinda Gates Foundation.
Anyway, in asking what are we up against? in telling humans the truth about themselves and what they're doing, there is no finer illustration than this Rosling video.
The telling (humorous? tragic?) moment comes just after the 2:45 mark. The video runs only 3:19 altogether.
You need to watch the whole thing. No cheating! Do not skip ahead! Context is everything!
