The uncaring way we treat the place, do we humans even really belong here, on this Earth?
I recall another good point Ray Anderson made in his book, Mid-Course Correction. He cited the case of the Fraser firs of eastern Tennessee, heritage forests from the last ice age, ravaged and reduced to almost nothing now by a species of insect accidentally introduced from Europe, against which the trees have no defense.
Anderson’s chilling point quotes the Forest Service report that as an exotic species, the parasite has no natural balance developed for its new ecological niche, and thus will kill its own host, and then die.
To me this sounds a lot like us, here.
Maybe those theories are correct: we ARE descended from aliens after all. If so, they were probably fleeing a ruined home planet.
