Saruman’s decline from the courtesy of his former days both reflects and contributes to the broader decline of Middle-earth from its past beauty and nobility. When Saruman stopped showing Treebeard kindness, he stopped showing the world kindness, beginning to consider the environment only as something to exploit and abuse. Treebeard, like the men of Rohan, is discovering that it will soon be impossible to be on nobody’s “side” in the coming conflict. Inaction is dangerous in such times, and if he wishes to oppose Saruman, who cuts down his trees and disrespects the land, Treebeard must act.
