"Soil is a resource, a living, breathing entity that, if treated properly, will maintain itself. It's our lifeline for survival. When it has finally been depleted, the human population will disappear. . . . Project you imagination into the soil below you next time you go into the garden. Think with compassion of the life that exists there. Think, the drama, the sexuality, the harvesting, the work that carries on ceaselessly. Think about the meaning of being a steward for the earth."
