We are able to recognize, anticipate and avert ecological collapse. No other animal can do this. The rest of the animal kingdom can only adapt, at best.
I think you both overstate human understanding of ecological systems and desire to maintain them.
Humans mostly tend to radically reshape local ecosystems for their own ends, at times collapsing them.
Aside from some very local remediation successes here and there (which are more repair jobs than preservation), I'm unaware of any evidence that humans have "recognized, anticipated and averted" any of note.
Farming and agriculture is ecological creation on a grand scale, and responsible for much of human flourishing, along with the animals and plants we cultivate.
Agriculture is an activity, not an ecosystem. Humans are but one element of the ecosystems in which they exist, and their flourishing is relevant only insofar as it preserves systemic viability.
Farms are inherently unstable - the 'system' is missing. From an ecological perspective, they're no more an ecosystem than you'd get if you released a bunch of random animals in your house. You'd have a new 'system' that lasts until they die.
That's just a semantic argument. Humans have an ability no other organism has to create and maintain biological systems. It is the only thing that could possibly save an ecosystem from collapse. If humans are eliminated, then so is this ability.
