:: The 4th Era ::

(Mexico/Central America) Mexico city seems to be built in the worst way possible. The original Aztec architects could not imagine the locational problems the city faces today. Originally built on an island, Spanish conquerors drained the lakes and created an inland, mountainous position that causes the city to sink inches every year. Ironically, the city is now forced to use underground water sources or expensively import drinking water and poor locals can rarely count on tap water. The uneven clay and volcanic soil foundation and climate change further drives subsidence of this unplanned metropolis. Climate change will also create a series of floods and droughts and the inefficient sewage and water system will lead to devastation.
