5 Places to Visit

CNN lists 5 places to visit before they're gone...like, for good. Interesting places, a couple that i've never heard of.
Better get cracking with the air miles :-)

1. Nauru - The over-extraction of phosphate has crippled the country's economy.
   
   
2. The Dead Sea - Evaporation and a lack of a water source is leaving a sad sinkhole in its place.
   
   
3. Mexico City - We were there, and there are some places where buildings are no longer structurally sound because of the uneven foundation.
   
   
4. Amish Country - I'd venture to say that the reason is not one most would expect.
   
   
5. Freetown Christiania - The Danish government thinking of taking back its land.
