Building for sporting events and costs.

There're series of derelict sporting facilities photos floating about in view of on-going Brazil World Cup 2014.  Mostly, we see facilities that are abandoned once international games like the Olympics end because people in the host countries never/ don't gravitate towards the sports that these facilities are meant for.  In conservation, the quickest death to any building is in its disuse, for with abandonment comes lack of maintenance and care.

Here're some examples of two facilities build for the Beijing Summer Olympics in 2008:

Beach Volleyball Stadium in July 2008:

 Beach Volleyball Stadium Now: 

 Rowing canals in 2008:  

  Rowing canals now:  

Other than the potential unsustainability of facilities for these major sporting events, there's also the question of whether or not the spending committed to the hosting of these events even begins to justify itself.  One of the key bone of contention in on-going anti-World Cup protests in Brazil is the obscene amount of money pumped into the event by the government, when the general conditions for workers, public welfare and facilities (e.g. schools) are not improving.
