A sign warning of the red tide risk is displayed at Lido Key Beach in Sarasota, Florida, on March 15, 2023. - With its brilliant sun, white sand and turquoise water, Lido Key Beach would make for a perfect postcard of Florida beaches if it weren't for the dozens of dead fish lying on the shore, killed by a toxic algae bloom known as red tide. The bloom usually hits Florida's Gulf Coast in the summer, but this year it has come during spring, a time when thousands of American families flock to the Sunshine State during school break, and the outbreak bodes ill for its tourism sector.
