I read a lot of Pacific naval history, and even visited Capt. Bligh's house in London. I also have enjoyed studying the history of the Bounty's crew on Pitcairn island...pretty amazing stuff.
I met a mission family at a church years ago that was attempting to get support for their work in Kiribati....they did not succeed in getting the church support, sadly. We were moved to help them, but it took much more....Missionary support is spotty at best.
But total reliance on the Lord works every time for us, though how and whom He does it through would not have been our choices.
Welll....ain't no marshlands in the middle of the Pacific, that I've heard of.
Where I live has both mangrove swamps and oil infused shale marshlands....which is black, and peaty, but not very sandy and not on the beaches.
