Living systems actively regulate water, stabilize soils, moderate heat, absorb shocks, reduce flood peaks, buffer storm surge, sustain food systems, support biodiversity, protect public health, and preserve the ecological conditions that make human communities viable

Ecosystem resilience is based in the so called natural buffers. They are a product of the interactions between life beings. Imagine the life bar in a videogame. A natural buffer is like a 4-D life bar, where each character actualize their life bars at the same time. You lose some life and your friends will change their energy automatically to fix your health bar, Is paid with energy but also needs some "time currency".

With healthy buffers, even big impacts in an ecosystem are absorbed and the system returns to the initial situation again and again. But it has a coast in the buffer. The life bar gets shorter.

When the buffer is spent, the system is not 'elastic' anymore. At this moment the danger is extreme, but the warnings are subtle or none. Just further impacts, even tiny impacts, on the ecosystem cause a total, devastating and irrevocable collapse that may extend over several years and can't be stopped.

Is unclear if we had crossed this line yet.

The life has recovered from huge collapses at a planetary level five times yet, but it needed millions of years for that.

Just because we had luck before, does not mean that we will have luck forever.

This coming from the leader of the other country in a war... I mean, I do find it credible that Xi might have told Putin to think very hard before doing something extremely stupid, but from there to stating that Russia is "China's vassal" and will do whatever they're told by a party who has long been a direct competitor (China and Russia have been solid "frenemies" for a long time, pushing very different views of what "real socialism" looks like)... It's a big jump.
