Whats going to happen with this oil mess?

I can't really call it a oil spill because it is still growing as I am writting this.  I was interviewed today by the local news in Miami NBC6.  They asked why when they interviewed the people at the Key Largo chamber of commerce they where told we had nothing to really worry about.  How can they say this? We make our living diving in the Florida Keys. When Katrena hit the gulf trash washed into the Palm Beach Inlet for weeks afterwards.  What is to stop this oil mess from doing the same?  A fellow diver friend of me Rick Iossi has done a great job pulling a lot of info about the path of the mess on his website  Florida Kite Boarding Forums
