WAS is there sometimes,but... I was walking many hours and days specifically thinking about it and observing long rocky cliffs that have wildflowers and berries growing on them, bees, some moths,monarch butterflies, bunch of tiny insects and beetles and hummingbird even hangs out there- and it occurred to me that at least these ones are really having good times with abundant food, exploring vast space along the ridge and always filled with wildflowers - no use for rocky land, no pesticides, no predators can easily get close etc. It just showed me that some species if taken to other planets will have possibility of almost permanent wellbeing and WAS is totally manageable, they would choose to be multi-planetary, i think, instead of just extinction on Earth

Many ideas about wildlife we get from documentaries, which mostly show actions and drama. But animals most of the time do whatever they are fine with (their nervous sys adapts to their situations  too). Question is would they choose to not have any experiences? If animals feel that bad they stop eating, but we see many hopping, chirping, playing,nest building. WAS is there too and we should help in many ways though. Also regarding multiplanetary...it depends. What if animal life on other planets gives them at least a survival chance for now, but will later become a paradise with help of some wise future beings, than it's all longterm- wellbeing future needs to be taken into account. Some measures should be taken to have on other planets only wildlife  coexisting well, maybe  some feedback logic that makes adding any unnecessary wildlife suffering impossible. For some species the balance seems heavily tilted toward neutral-to-positive time rather than constant hardship.There are species that seem to not cause suffering (monarch butterflies come to mind ), likely they don't know what it is too, and other planet maybe their only chance to not become extinct. But planning, observing evolution of what we bring to other planet and fixing issues is probably superintelligence level hard question.
