What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another.
A society grows great when old men plant trees whose shade they know they shall never sit in.
Plants do not grow merely to satisfy ambitions or to fulfill good intentions. They thrive because someone expended effort on them.

When one of us plants alone, the seed might not sprout. But when many of us plant together, the roots grow deep, the tree stands strong.
A garden is a grand teacher. It teaches patience and careful watchfulness; it teaches industry and thrift; above all, it teaches entire trust.
The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.
