What should we do?

What should society do for "uncivilized cultures" like the Sawi?

Since the world is growing and technology is advancing, the uncivilized tribes should also get a new life and meet new ages to survive. Missionaries are there to fix the tribes' belief into Christianity and teach the uncivilized societies how to live in comfort. Therefore people all over the world could support the uncivilized groups by donating money to the organization that supports the native tribes.
