People engaged in disputes bring with them their own cultural world views. Differences in world view make it difficult for parties to find the shared experiences necessary to reach common ground. The dispute over treaty rights is about distribution of a finite resource that is shared by both communities.
Many differences exist between the two cultures but one is a fundamental difference in world view.
We are different because we are indigenous people. To be indigenous is to be so inter-connected with the land, the ecosystems, that it is part of you. Nothing is closer to the land and resources as being part of it. Our ability to survive was based on our ability to understand the land. In order to survive, indigenous people learned the cycles of production and harvest in Nature.
