“The desert was bad, but nothing could compare with the horrors of a tropical rain forest.”

“Compared to forest or aquatic ecosystems, grassland is unstable. It requires rather precise geological and climatic conditions, and if these conditions are not maintained--if too much rain falls, or too little--it quickly turns into forest or desert, both of which are dominated by woody plants. This instability is reflected in the spectacular but brief careers of various grassland faunas. Humanity, with its dazzling symbioses, preadaptations, and neoteny, is the most spectacular of these--and may well be the briefest.”

“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.”

“An oasis of horror in a desert of boredom.”

“A forest is mystery but the desert is truth. Life pared to the bone.”

“A tree looks a lot taller in the desert than it does in the forest.”
