Trees definately breathe, and they definately have pulses, and they definately feel... To me that's just as real as thought. Whether or not they think in English or Treeish, no idea. They're prime examples of Zen.
"Why should there be hunger and deprivation in any land, in any city, at any table, when man has the resources and the scientific know-how to provide all mankind with the basic necessities of life?" ~Martin Luther King, Jr.
