There is an overriding theory in physics known as entropy: Energy is continually moving from a higher state of order to a lower one. Ski down a hill that starts out steep but ends in a long flattish plain and you’ll eventually come to a stop. You’ve reached an end entropic state. Having come to a standstill, should a cataclysm all of a sudden remove the ground from under the plain, you would freefall down until you hit solid rock. You will have reached a second end entropic state.
Woods, before Lyme disease, were the child’s other playground. Shimmy up trees, play cops and robbers, hide and seek, and all the time aware of the trees, leaves, bushes, open spots, learning ecology without knowing it.
