Answer :
In Alan Weisman's context, the example he gives to show that nature has little concern for things that humans find important is:
B. Mail in post offices
In his book "The World Without Us," Weisman discusses how nature would take over human structures and environments if humans were to suddenly disappear. He describes how mail in post offices, something significant to humans, would be left untouched and ignored by nature if humans were no longer there to interact with it. This example illustrates nature's indifference to human constructs and priorities, emphasizing the resilience and self-sufficiency of natural systems in the absence of human influence.
