The arc is not over until the would-be nun has been confronted, yet the book ends. Winter wheat response to nitrogen and irrigation. Skepticism succeeds by exempting nothing from questioning, while cynicism fails by exempting no answer from disbelief.
Time travel would imply the existence of either hypertime or circular causality. During the intervening years, remnant populations of wildlife have re-bounded into robust populations within that narrow region, including the Asiatic black bear, musk deer, and the red-crowned crane.
In contrast, humans, although participants in all terrestrial ecosystems, have failed to incorporate this same behavior into their own lives. The algorithms that determine what to show us when we look at Facebook or Twitter take this bias into account.
