There is a whole earth ecological biological balance in place. The earth and life as we know it has developed within the system. Changing the status of any one species, changes the status of those in the life cycle. The Plains Indians lived carefully within this balance harvesting a buffalo when needed and using everything the buffalo provided for something, from the meat to the skin to the bones. A study of all the early cultures shows this respect for the environment and the lifecycle balance. They had the right idea. We need to be more aware of this balance and try to live within it. I say try because while I hope we can, I am not sure if it is possible.
