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.
Just because it is too late for modern societies to be maintained, does not mean it is too late for influencing the future. Just because it might be too late to significantly influence that future, does not mean it is too late to learn how to participate less in destructive or delusional behaviours.
