In our last workshop we talked about the sustainable practice of storytelling.  We held this at the wonderful Village of St Elmo in mid-city Los Angeles. The workshop commenced with a storytelling by Haqqika Linda Bridges, a storyteller, about the late Kenyan Nobel Laureate Peace Prize Wangari Maathai .  She was instrumental in teaching her people about the importance of trees have in our society, the environment, and peace. 
In the hands on learning segment, we researched through various sources of media to find how many manufactured things in the world are made of trees.

We learned that trees can communicate with each other through extensive root structures in the earth called fungi (mycelium).  These mycelium act like our modern human version of the Internet or world wide web by transferring information form plant to plant.  
Some cultures have the creativity to work with tree roots to our benefit by constructing marvelous structures without killing trees. Check out this link about the people in the southern Khasi and Jaintia hills and living bridge . They use storytelling to transfer this knowledge from generation to generation.
