Once upon a time a group of friends were seeking a place to call home. The desert was too hot, the valley was too wet and the mountain was too windy.
Then they found the forest. It was perfect. The leaves gave shelter from the sun and rain, and a gentle breeze wound through the branches.
But the friends soon wanted to build shelters. The shelters became houses, then the houses got bigger. All too soon they wanted to control the environment and built a huge wooden wall around the community.
As they cut down the trees, the forest becomes thinner, until there is just one last tree standing.
