" These days, startling though the thought is, we control our own legacy. We’re not passive, we’re not helpless. We’re earth-movers. We can become Earth-restorers and Earth-guardians. We still have time and talent, and we have a great many choices. As I said at the beginning of this mental caravan, our mistakes are legion, but our imagination is immeasurable. "
