You and I are trustees. Nothing belongs to us personally. The resources of our planet have been entrusted to every one of us together. Like good bank trustees, we are expected not to squander these resources but to invest them wisely for our beneficiaries: the rest of life, especially the generations to come.The trust includes not only the lives and natural resources of the planet, but our inner resources as well. This has practical implications. We can lessen our potentially exhausting impact on the earth by simplifying our desires and demands. Simplicity is the key to trusteeship.
