If you lose touch with nature you lose touch with humanity. If there's no relationship with nature then you become a killer; then you kill baby seals, whales, dolphins, and man either for gain, for "sport," for food, or for knowledge. Then nature is frightened of you, withdrawing its beauty. You may take long walks in the woods or camp in lovely places but you are a killer and so lose their friendship. You probably are not related to anything to your wife or your husband.
A man's house burns down. The smoking wreckage represents only a ruined home that was dear through years of use and pleasant associations. By and by, as the days and weeks go on, first he misses this, then that, then the other thing. And when he casts about for it he finds that it was in that house. Always it is an essential - here was but one of its kind. It cannot be replaced. It was in that house. It is irrevocably lost...It will be years before the tale of lost essentials is complete, and not till then can he truly know the magnitude of his disaster.
We travel together, passengers on a little spaceship, dependent on its vulnerable reserves of air and soil, all committed, for our safety, to its security and peace. Preserved from annihilation only by the care, the work and the love we give our fragile craft.
