Tiny bug, massive damage

This book should be required reading for people who still laugh at those stale dinosaur-flatulence jokes whenever the topics of environmental degradation and global warming come up.

Earth-orbiting astronauts and airline passengers crossing the Rocky Mountains can't miss seeing vast and ever-widening patches of red and grey among green-canopied pine forests, stark evidence of a growing empire fashioned by minuscule architects.

Worldwide there are similar scenes, far-flung territories belonging to an empire so old and adaptive that it once included dinosaurs and today controls the vagaries of our continent's huge lumber economy.
