Mention a sinking city and it is a fair bet that Venice is the place which comes to mind, yet parts of the centre of Mexico City are sinking at an even faster rate than that of the fabled Italian lagoon city.Pete's Points:
Apparently the fact that there are now over 20 million people living in this city is partly what is responsible for this phenomenon.
Australians need not worry, unlike Mexico city it is unlikely that Australia will also sink into the abyss.
Mexico city is built on a lake bed. As the people in the city grow in number they are drinking the aquifer that is underneath them dry and this of course causes subsidence.
For the first time in history it is possible to say that a group of people are literally drinking themselves into the ground and this time with water!
