Using trees as a symbol of peace is in keeping with a widespread African tradition. For example, the elders of the Kikuyu carried a staff from the thigi tree that, when placed between two disputing sides, caused them to stop fighting and seek reconciliation. Many communities in Africa have these traditions.

We are called to assist the Earth to heal her wounds and in the process heal our own - indeed, to embrace the whole creation in all its diversity, beauty and wonder.
