“I have strong memories of many moments of joy and amazement when I lived in the tropical rainforest: listening to the deep reverberations of chimpanzees drumming against large tree buttresses to mark their territories, or watching from the terrace of my bungalow in western Ghana as the carmine sun turned deep purple before going down over an unbroken canopy of rainforest trees. I remember my astonishment when big fish belonging to half a dozen different species jumped into our boat as we drove slowly up a narrow tributary of the Amazon River.”
