Many Island nations in the South Pacific are rapidly becoming uninhabitable, unable to support agriculture as salt water percolates from the ground. In some cases they can no longer bury their dead as the water table has risen to the point that coffins literally pop out of the ground.

Families are being torn apart and society is beginning to break down with some choosing to leave and others refusing to abandon the only homes and way of life the have ever known.
