Recover is the last critical mission area in Homeland Security.  Recover means to bring back the affected area from the disaster to normal. This effort begins once the immediate threat to human life has ended.  For example, once a fire has been put out and there is no longer a threat to human life, cleaning and clearing the area is needed.  If the fire affected damaged buildings or homes, these will be reconstructed and fixed.

This is much like after a wind storm your parents will be cleaning out the leaves and weeds from the garden to bring the garden back to its normal appearance. 

This is the last critical mission area because it is very important that our lives return to normal after an emergency as quickly as possible.
