The nation of Kiribati is eyeing a plan to purchase 6,000 acres of land on Fiji's primary island, Viti Levu. Why? Because their population of 103,000 people may have to end up living there. Rising sea levels have gotten to the point where Kiribati, which lies very close to sea level, is seeing its freshwater reserves being increasingly contaminated by seawater coming inland. Or at least what passes for inland in Kiribati.
They're hoping it doesn't come to that. Nobody's hoping it comes to that. But it's looking increasingly likely that it will.
