The Florida Department of Environmental Protection confirms reports of blue-green algae in Saint Lucie County. The news has some residents thinking about the algae crisis in 2016. “Oh, it’s already worse. It’s already worse,” said George Sawley. “From the satellite they’re showing, it’s almost 80 percent of the lake that has green algae on it. So where’s it going? It’s coming here, as soon as they open it up,” he added. Sawley offered WPBF 25 News a boat tour along the St. Lucie River to look at the algae firsthand. Neon green film covers areas of the river. “If you had any fish here, they’re all dead now. It’s all algae accumulated. Look, here’s a dead fish. This is a direct result. This is killing everything across the board,” Sawley said. He points to another area of concern: health effects. “We can see the lasting impact on other creatures, but what about humans?” he said. “I’ve talked to local people that feel that they’re having respiratory issues from it. I have talked with people that work around the water who are getting infections around their hands and feet,” Sawley said. That’s partially why Stuart-based Bullsugar is organizing a documentary viewing Tuesday night titled "Toxic Puzzle."In it, doctors link chemicals from toxic algae to neurological diseases like ALS, Parkinson’s disease and Alzheimer’s disease. “They’ve found, or believed they’ve found, extremely strong correlations between exposure to signo-bacteria and the development of those diseases later in life. They see an elevated risk;” said Peter Girard of Bullsugar. Right now, there is no concrete evidence to back up those claims from organizations like the CDC. However, it is something the medical community has long been asking for. “Well, I think it’s a disgrace that our politicians have been warned and told about this for quite some time and they’ve done nothing about it;” said Sawley. The documentary starts at 6:30 p.m. at Star Struck Theater in Stewart, with an open forum with the doctors from the documentary immediately afterward.
