🌊 The Bottleneck of the East: Geography of a 1.5x Tsushima Island
🌊 The Bottleneck of the East: Geography of a 1.5x Tsushima Island Welcome back to The Worldsee. In our #IFGeography series, we have engaged in extreme planetary engineering, draining oceans and expanding mountains into the stratosphere. Today, however, we take a more conservative, highly realistic approach. We travel to the Korea Strait to manipulate a small but geopolitically critical landmass: Tsushima Island. In our reality, Tsushima is a mountainous island archipelago covering about 708 km², acting as a stepping stone between the Korean Peninsula and the Japanese island of Kyushu. It is famous for its dense forests and the deep, winding ria coastline of Aso Bay. But what if we expanded this island by exactly 1.5 times? Scaling Tsushima up to roughly 1,062 km² (slightly smaller than Okinawa) does not create a continent, but it drastically alters the physical geography of the narrow sea corridor it occupies. Let’s explore the realistic, conservative geographical shifts of a 1....
