" It was a sunny day in early summer, and he could hear birdsong. In a nearby orchard that had so far escaped shelling, apple trees were blossoming bravely. Men were the only animals that slaughtered their own kind by the million, and turned the landscape into a waste of shell craters and barbed wire. Perhaps the human race would wipe itself out completely, and leave the world to the birds and trees, Walter thought apocalyptically. Perhaps that would be for the best. "

― Ken Follett , Fall of Giants (The Century Trilogy, #1)
