I thank you brother deer for your sacrifice and Mother Earth for your gift. It is nary a thought while we scarf down the burger. The people giving prayer for their meal hold the gift and sacrifice sacred. So in a world where we go through natural resources without thinking of how limited it is or how damaging it is to overuse we do not hold much sacred. To keep a natural environment we are supposed to hold nature and its ways sacred and to protect it.
Indigenous peoples learn early in life to respect everything's place in life.
In chapter one there is a short description of the Warlis, where it describes how they live. They are careful only to take what they only need, live in simple mud and stick homes, and use renewable materials. Their religion is also based on the Earth-type Gods and Goddesses. What they hold sacred is nature and because of that they also hold the natural environment sacred as well. The relationship in this case between the sacred and the natural environment is that the natural environment is the Sacred.
