Or we can assume that the state of the world before humans was a state that we have deviated from though human agency, and it is reasonable to remedy some of that irreversible trajectory would be a good cause that some other intelligent species could undertake after we're gone.

The first known extinction event was caused by cyanobacteria that released vast amounts oxygen (highly toxic chemical) into the atmosphere. It killed most of the anaerobic life, clearly "deviating from the previous state of the world". The time has come to "remedy some of that irreversible trajectory".

The whole notion that the "current trajectory" is somehow objectively bad is ridiculous. It may be bad for humans though.
