Dubai World Sinking
In 2008, work on the project was put to a halt. While officially the project has just been delayed, the islands are rapidly merging together and also appear to be sinking. There is just one island with a building on it. It is questioned if the islands can not be accessed by boat due to the shallow waters.
The developers claim 60% of the islands have been sold. There were various plans for the developments, varying from luxury homes to holiday resorts or even a very luxury bar (on Monte Carlo).
Dubai's development has long been criticized by environmental activists, who say the construction of artificial islands hurts coral reefs and even shifts water currents. They point to growing water and power consumption.
