This is a fantastic tale against the Malthusian ideas, and similar decision to sacrify few humans to save the group.
If you can do that at the last minute, when deaths it staring at you in the eyes, don't do that using prediction model, deciding to let people die, to kill them, to same "the planet", "the group" "the nation"...
you never know is behind the dune there is a surprise.
This episode inspired me, and make me resist to current fashion.
And guess what ? I have seen beyond the dune, and yes we are saved, once again.
