Preventable post-disaster

There is enough information online, in the newspapers, on TV and radio about Hurricane Katrina yet I have to add a brief two cents.

Nobody knew that a tsunami would hit Asia but enough people knew that New Orleans was at risk of levees breaking, etc., and still the efforts to prevent the degree of devastation that has now occurred was an afterthought. I am disgusted and saddened by the unnecessary lives lost, homes destroyed, and hard work now completely gone for countless families.
