Catrina was a hurricane which caused all New Orleans in flood. People who died in this disaster were over 1000. At least 1 million people had evacuated from this area. A mayor of New Orleans had declared that this city could not live at least 3 to 4 month because the poison chemical, gasoline, the excrement from human beings, and the dead body would cause the disease. There were still 100 thousand people stocked at there. However, the public security was broken and people had started to raise the price of gasoline. It was really horrible. All the contribution from all over the world and the Red Cross also had taken part in to help the citizens through this natural disaster.
