Wilderness holds answers to questions men have not yet begun to ask.
      - Nancy Newhall. 

 Some of these questions are scientific or ecological, some of them spiritual.
      - Bill Devall, Simple In Means, Rich In Ends; Practicing Deep Ecology.

 With our vast knowledge we are hounded by doubt.  Just the fact that the smallest structures of matter with their neutrons and protons move with the same precision and order as the galaxies, that solar systems are dying and being born again, makes us wonder and question the purpose of all we have learned. We also know there are certain things that cannot be measured scientifically, secrets that defy rational deduction, with no answer to the concepts of love, imagination, or the flowering of man's mind.
- Sigurd F. Olson, Reflections From The North Country

There are billions of times more stars in our universe than there are grains of sand on our Earth.
     - Jay Barbree & Martin Caidin, A Journey Through Time, Exploring the Universe With The Hubble Space Telescope

 In orbiting the sun, the Earth departs from a straight line by one-ninth of an inch every eighteen miles -- a very straight line in human terms. If the orbit changed by one-tenth of an inch every eighteen miles, our orbit would be vastly larger and we would all freeze to death. One-eighth of an inch? We would all be incinerated.
