Natural environment sustains the life of all beings universally. Trees are referred to in accounts of the principal events of Buddha's life. His mother leaned against a tree for support as she gave birth to him. He attained enlightenment seated beneath a tree, and finally passed away as trees stood witness overhead.

In today’s highly interdependent world, individuals and nations can no longer resolve many of their problems by themselves. We need one another. We must therefore develop a sense of universal responsibility . . . It is our collective and individual responsibility to protect and nurture the global family, to support its weaker members, and to preserve and tend to the environment in which we all live.
