Native American lore is an important part of the Scouts BSA and Cub Scout programs. You have to be a little careful when dealing with spirituality and religion, so know your unit. This Native American prayer is probably generic enough to not offend the sensibilities of most scouts. It would fit in really well with a conservation theme.
This prayer is attributed to Chief Sealth (for whom Seattle is named).
Native American Prayer
We belong to the earth this we know
The earth does not belong to us;
We belong to the earth , this we know
All things are connected like the blood which unites one family.
All things are connected.
Whatever befalls the earth befalls the sons and daughters of the earth.
We did not weave the web of life;
We are merely a strand in it.
Whatever we do to the web, we do to ourselves.

Before using Native American traditions or imitating them, think about how your actions might be interpreted. A Scout is respectful of other people’s faiths and cultures.
