" Planting nuts requires a vision for a future that goes beyond one’s mortal reach. If we envision ourselves as participants in the same grand, complex web of interactions as the forest, then planting acorns is like planting part of ourselves. The morality that comes from such a vision of ecosystem-as-life is a common thread that, if taught and encouraged, could unite all of mankind. "
