A fibonacci spiral, but not.
Entrenched physically: an artificial mountain. Preserved legally:
Tree Mountain itself can never be owned or sold, nor can the trees be moved from the forest.
Still a work in progress:
The planting of trees holds the land from erosion, enhances oxygen production and provides home for wildlife. This takes time and it is one of the reasons why Tree Mountain must remain undisturbed for centuries
and embedded in families (is this really the work?):
People who planted the trees received certificates acknowledging them as custodians of the trees. The certificate is an inheritable document valid for twenty or more generations in the future – the first such document involving the future in human history.
