Total fatalities in Katrina? 1833 (FEMA). Total cost of Katrina? About $41.1 Bilion.
Though we don't know the final death toll, the cost will be unbelievably enormnous and the hurricane season isn't even over.
We can keep building and re-building and 'hurricane-proofing' but as one can tell, in the long run it doesn't save anywhere near as much in costs as is practical. It surely has saved lives.
Whether it's climate change or cyclical hurricane activity, moving cities and populations away from repetitively dangerous locations needs immediate discussion and action.
Florida, Georgia, Louisiana and the Caribbean area all on the table for long term planning discussions.
The dangers are in human lives and budgets we can't keep funding.
