There have been natural disasters since the beginning of recorded time, way before the invention of the destructive technologies you describe.
Had those been blessed with the available technology that is still in it's infancy today, people may not have had to suffer the destructive forces of nature. Sattelite imaging, seizemic reading for the potential for earth quakes, even the Tsunami of a year ago or so that wiped life out on such a grand scale, could've been lessened due to the fact that there were warnings as to the Tsunami's destructive power that could've been sounded, but because of business & industry not wanting to cause a potential shortfall financially, in the event that there was not as big a problem as they would've believed to be, in thier limited reasoning, several more thousands of people were killed as a result of human greed.
The world is by no means perfect in the condition that it's in. There does exist the potential for the planet to be a paradise, in a state where we have God's eternal blessing and backing. There are answer to questions that only cause more questions to to be asked. I don't discount the loss of life that's going to come as a result of this hurricane as well as host of other things that are certain to come afterwards, I still believe that God will make a fair accounting when all other things are brought to the otherside, as in life, also in death, be it by 1 or in the numbers unable to be counted.
