The survival of wilderness -- of places that we do not change, where we allow the existence of creatures we perceive as dangerous -- is necessary. Our sanity probably requires it. These places function, whether we intend them to or not, as sacred groves -- places we respect and leave alone, not because we understand well what goes on there, but because we do not.
Work is work and there's harmony in it when the dignity it deserves is allowed to thrive naturally. The greatest teaching manual labor provides a contemplative practice is that there is no separation between work and prayer: work is prayer and prayer is work.
