"Who has the time to feel the earth beneath their feet, or the wind in their hair, or the sun on their face?"

"One way to open your eyes is to ask yourself, 'What if I had never seen this before? What if I knew I would never see it again?'"

"Our heedless and destructive uses of the earth's resources are a form of self-destruction."

"I find the greatest wonder in the smallest things."

"The most serious threat to mankind comes from within, from our own arrogance and ignorance."
