Remember, WW2 didn't bring civilizational collapse. In fact one could argue it even accelerated industrial development. Doesn't mean much to those who perished.
It depends where you lived.
It sure did in China, Japan, Germany, large chunks of the USSR.
Civilisation was rebuilt, but it sure collapsed.
Perhaps the author of that comment comes from the USA?
We're killing what we eat (and what we eat is nurtured by) at a rapid speed, at scale. This will first show in bearable price increases (as it already does with coffee and cocoa) and only get worse from there, think famine (in regions where this has not happened in a lifetime).
Good luck with keeping a civilization 'stable' when people are hangry at scale.
And the worst part is: While war can be ended, un-extincting is not a solved problem at all.
