World View-a conception of life.
There are generally two world views:
A Eurocentric world view stemming out of imperialism and industrialization that the resources of the world are for our exploitation
A more Indigenous world view that recognizes that humans are part of a larger web of life, having the same rights as other beings-no more, no less.
