The scale of damage from hurricane Katrina is hard to imagine. Even before the New Orleans levies were breached entire cities had been nearly destroyed. New Orleans' plight increases the scale beyond belief.
It's hard to fathom what happens when most of a city is flooded. Those who could afford to evacuated, and are now trapped away from home with only what they could carry. Many have no homes to which they can return. They also often have no jobs, no income and no prospects for the short term. This photo was one of many great ones at WWLTV.com.
Those who could not afford to leave are in worse shape, if they survived. ABC News said that "In New Orleans, a third of the residents live below the poverty line. The very poorest live on the lowest land, south of Lake Pontchartrain, where the flood water is now up to their rooftops."
BoingBoing posted an email from a New Orleans rescue worker that said "Forget the sanctimonious bullshit about the bullheaded people who wouldn't leave. The evacuation plan was strictly laissez-faire. It depended on privately owned vehicles, and on having ready cash to fund an evacuation." The same email said that "Entire teams are working on nothing but evacuating the hospitals. All four of the major hospitals are beginning to flood. Critical patients have to get out or surely they will be lost."
I can't easily afford to donate right now, but figure that I'm so much better off than even those who left that I have given more than is comfortable. Please give what you can. Reportedly the American Red Cross donation page is working slowly, but you can donate to Red Cross via Network for Good with no delays.
Don't send clothes! Several years ago friends were sent as part of an Americorps/VISTA disaster response team, and reported that clothing and other donations hinder rescue efforts because people have to manage and process the items given. At later stages clothes might be helpful, but right now cash is the best thing you can send.
