Sunday we drove to the Aquarium of the Americas and watched an IMax movie called Hurricane on the Bayou. It discussed the wetlands, and how they are disappearing, which contributes to the devastation caused by hurricanes, especially Katrina. The wetlands provide a natural barrier for hurricanes, they said that for every 3 miles of wetlands, a hurricane's height decreased by a few feet. That can make an incredible impact, and prevent a lot of damage to the surrounding area. However, because of man-made canals and levees, the wetlands have slowly been disappearing over the last 50 years. The canals dug to provide a path for oil barges bring in salt water from the ocean, killing the trees. This is a man-made problem, that requires a man-made solution. The dilemna begins when we consider just how dependent we are on oil.

It would interesting to see the IMAX movie Hurricane on the Bayou. I had no idea that the disappearance of the wetlands could have such a negative impact on the effects of a hurricane.
