What do mission organizations do for these people?

Mission organizations like Don Richardson and other missionaries do various things for people like Sawi tribes. But there main purpose is to spread God's message to those who don't know God's faith yet. God has plans for each and everyone in this earth. Just as a father who would love his children more than anything in the world, God loves us more. Missionaries are basically the messengers who help these people realize God's existence and His plans for them and everyone else. Personally, I think that the missionaries are heroic and courageous. It is absolutely a risk to sacrifice yourself and devote your entire life to help atheists places all over the world. If I were them, I WOULD NOT be able to take such risks such as going to barbaric and cannibalistic tribes and spreading God' s plans and his message to this world we live in. But I would be always be willing to share with others about God's impact in my life and who He is and why he sent his one and only son to die for us, sinners. By looking at the greatest change that the Sawi tribes had made, I once again realized how powerful God's faith and Christianity was.
