Civilizations rarely collapse in moments of chaos.
More often, they decay through a sequence of decisions
designed to postpone accountability.
By the time destruction arrives, it feels abrupt
only to those who refused to look directly
at what was already happening.

At some point, there were way more driven/ridden horses than wild ones.
Currently, there are substantial numbers of cows, chicken, pigs and so on raised by humans and almost no wild brethren of the above mentioned animals. Same with quite a number of plants.

Are we even aware of the whole situation?

Why?
Because so few of us are still needed when it comes to ‘raising food’?

I’m afraid we’re very soon going to face the consequences.
Directly!
