One of the issues is ----your trying to change and adapt a culture in just over a century that lived that lifestyle since the dawn of time----not an easy task
gets harder and more confusing as well now when technological change reaches those once remote areas and the young people attempt to imitate what is beamed across the airwaves.
Ongoing also is the lands promised under treaty which were once too remote to mean anything---suddenly have resource value----ooopps
So in a nutshell-----no easy answers.
