Red Tide Arrives in Santa Rosa Beach, Florida

Is the Red Tide upon us?  First I heard from a friend in Jacksonville that she was having a scratchy throat and some serious breathing problems, then to the west, in Houston, I heard about the same thing from family members, and new for the past few days, I am experiencing the same stinging, burning breathing problem they described.  Historically, the Red Tide kills a lot of fish, but just what is the source of the symptoms?  Wikipedia calls the Red Tide a phenomenon know as algal bloom. The phenomenon produces a neurotoxin called brevetoxin, which kills fish, birds, marine mammals and other organisms.  Let's hope it ends soon.
