Well, as CNN has reported, we also have the matter to the toxic, infected, mosquito-breeding soup in which any one in New Orleans is now living. Those reporters you see wandering in multi-foot deep water may not know it, but they are taking their lives in their hands: Typhoid, cholera, typhus, malaria, dengue, even yellow fever. These are things Americans think are third-world matters. They are now going to be New Orleans issues: http://www.usnews.com/usnews/health/articles/050110/10health.b.htm . Also, as CNN pointed out, there is the matter of disoriented animals (and people) wandering the rubble etc etc. I think we are going to see something ghastly. As bad as Andrew was, the aftermath took place on dry land in places the rescuers could get to. This is happening in an inaccessible toxic swamp hundreds of miles wide.
