"As I sit, my back leaning against a damp, moss-covered tree trunk, my eyes sweeping the canopy above, my ears straining to catch the crack of a distant branch that betrays an orangutan moving in the treetops, I think about how we humans search for God. The tropical rain forest is the most complex thing an ordinary human can experience on this planet. A walk in the rain forest is a walk into the mind of God."
— Birute M.F. Galdikas (Reflections of Eden: My Years with the Orangutans of Borneo)

""If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?""
