A Green Thought:
We are a part of the earth and it is a part of us. The perfumed flowers are our sisters; the deer, the horse, the great eagle, these are our brothers. The rocky crests, the juices in the meadows, the body heat of the pony, and people - all belong to the same family.
So teach your children what we have taught our children. Whatever happens to the earth happens to the children of the earth. If you spit on the land, you spit on yourselves.
The earth does not belong to us; we belong to the earth. All things are connected, like the blood which unites one family. Mankind did not weave the web of life. We are but one strand within it. Whatever we do to the web, we do to ourselves. All things are bound together.
One thing we know, which the white man may one day discover: our God is the same God and this earth is precious to Him. To harm the earth is to heap contempt on its Creator. Continue to soil your bed, and you will one night suffocate in your own waste.
When the last red man has vanished from this earth, and his memory is only a shadow of a cloud moving across the prairie, these shores and forests will still hold the spirits of my people, for they love this earth as the newborn loves its mother's heartbeat. So if we sell you our land, love it as we have loved it. Care for it as we have cared for it. And with all your strength, with all your mind, with all your heart, preserve it for your children.
