August 29, 2018 — SIESTA KEY, Fla. — Even as she sat under the brilliant Florida sun, her toes covered in sugar-white sand, Alex McShane wasn’t exactly enjoying her summer vacation. Florida’s worst red tide in more than a decade had turned the aqua-blue surf to a rusty dull brown.

And then there were the lifeguards. They were wearing gas masks.

With no mask of her own, McShane, 24, wore a frown. Her eyes itched, she coughed, and the stench was giving her a headache — all telltale symptoms of the monster algal bloom spanning the southern Gulf Coast. It is killing untold numbers of marine animals from Bradenton to Naples, where rotting fish still lay scattered on a beach behind Gov. Rick Scott’s seaside mansion, even after a cleanup.

As the outbreak nears the year mark, with no sign of easing, it’s no longer a threat to just marine life. Business owners in the hardest-hit counties report they have lost nearly $90 million and have laid off about 300 workers because of the red tide and a separate freshwater algal bloom in the state’s largest lake. Together, the two blooms have caused a sharp drop in tourism.

A pair of toxic algal blooms striking the state at the same time is rare and, in this case, especially lethal. A red tide is a natural phenomenon that develops miles offshore before making its way to the coast, where it feeds on a variety of pollutants, including phosphorus and nitrogen from fertilizer, along with other runoff and wastewater.
