In the middle years of my life I lived on four acres of land in Connecticut, a meadow completely enclosed within a forested wildlife preserve. It teemed with creatures: deer, squirrels, raccoons, a woodchuck family, turkeys, songbirds, crows, a Cooper’s hawk, even a pair of coyotes. Except for the hawk, every one of those animals constantly and fearfully watched over its shoulder lest it be caught, torn, and eaten alive. From the animals’ point of view, my edenic four acres were a war zone.
