What do we mean by living in harmony with the earth? Does it mean that you never kill, that you live in a log cabin, that you don’t reproduce, that you own nothing? Of course it doesn’t. In practice, what it means is that each of us keeps trying (in our own ways and at our own pace) to lessen our impact upon the earth and its life.
“I wish it need not have happened in my time,” said Frodo. “So do I,” said Gandalf. “And so do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given to us.”
