Historically, humans get serious about avoiding disasters only after one has just struck them. 62 that logic. 2006 should have been a breakthrough year for rational behavior. With the memory of 9/11 still 63 in their minds, Americans watched hurricane Katrina. the most expensive disaster in U.S. history, on 64 TV. Anyone who didn´t know it before should have learned that bad things can happen. And they are made 65 worse by our willful blindness to risk as much as our 66 to work together before everything goes to hell. Granted, some amount of delusion (错觉） is probably pan of the 67 condition. In A.D. 63.

Meanwhile, New Orleans officials have crafted a plan to use buses and trains to_79_the sick and the disabled. The city estimates that 15.000 people will need a _80_ out. However, state officials have not yet determined where these people will be taken. The_81_with neighboring communities are ongoing and difficult.
