The Sinking Kansai International Airport (KIA)
Kansai International Airport is one of the ten marvellous engineering civil structure in the 20th century. It's completely built on the artificial island, 3 mile from shore, promoting economic development and avoiding residential problems such as great noise and relocation. However, since it was built, it' seems to be doomed to sink to the sea. Especially in the current era, the fate of KIA is more uncertain, under the global climate evolution. To investigate more money on maintenance, or just leave it as it is, it's a serious question.
