Yeah, a lot has changed indeed, and I&#x27;m not surprised that many things were &quot;better&quot; before. Population density rise takes its toll. The endless cities are indeed a thing, wouldn&#x27;t be totally surprised if the plain on west side of the island would become a sort of mega-city spanning the entire length.<p>Seems like river-relocation is also a quite common thing (see e.g. Taipei&#x27;s Neihu area in the NE, bunch of smaller examples too).
