  • Climate.
  • Warm water from the gulf of mexico has lots of energy.
  • New Orleans is below sea level. prone to flooding.
  • High, dense population due to urbanisation.
  • Levees were not big or strong enough to hold the strom surge.
  • Oil drilling caused the land to sink. 
  • Human interference with the land, caused the land to sink further. For example, engineers drained wet lands to allow for more housing for the increasing pouplation. These wet lands would have been able to lower the impact of the storm surge, if they were not drained.

  • Aid was offered from around the world
  • The UK offered 350,000 army meals, but were rejected because of laws on mad cow disease.
