My very unscientific take is the noises are the result of a mundane mechanical process that is a consequence of the plant not having enough water or loss of water due to cutting, which leads to some cavitation bubbles forming. So it may only be as interesting as saying that your water starts "screaming" when it is being boiled.

Vegans aren't going to have anything to eat now... /s In all seriousness, this is wild.

What's wild about it? Plants shrink when drying up and that collapses tiny cavities in their stems. It's only surprising that this sound can be detected so easily.

It's not quite clear yet how the plants make these sounds, but the scientists suspect it is a passive process linked to cavitation. This is when plants that are stressed pop air bubbles in their circulation system causing vibrations in the plant.

A situation the plants evolve specifically to avoid and signal to every other organism in ear shot that the culling is coming

Isn’t that enough?

My body bloats in a passive process after it stops functioning, I avoid that

Makes sense, it's hard to see see an evolutionary purpose to this.

We know basically nothing about the world around us.

So true, this has become one of my mantras.

How do you mentally frame it. Like "ignorance is acceptable" or "we are limited beings"

I think as long as we are within the realm of reality, no single person or species can know everything so we need to accept contextual knowledge will be out limitation.

I often wonder to what level will we need to know someone to be able to satisfy abstract statements.

"Scream" is a sensationalist word, it anthromorphizes plants. You might as well say you can hear them sing Chop Suey's lyrics when they get cut down: Father, into your hands I commend my spirit Father, into your hands Why have you forsaken me? In your eyes forsaken me In your thoughts forsaken me In your heart forsaken me, oh

No, that is not enough.
