If you do microcredit with men, they tend to quickly drink it. They don't pay you back.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.
