Florida’s Red Tides Worsened by Pollution, Climate Change

"A task force appointed by Gov. Ron DeSantis is calling for research and investment in mitigation. Environmentalists say the real fix is cracking down on polluters."

"A task force appointed by Florida Gov. Ron DeSantis to address the state’s algal bloom crisis concluded in a recent report that “without hard work and careful planning” adverse human health impacts and widespread wildlife mortality would most likely “worsen” because of climate change and the state’s growing population.

The blooms are caused by high concentrations of a plant-like microscopic organism known as Karenia brevis fed by nutrients in runoff from stormwater, agricultural lands and wastewater treatment plants. A key stimulant is phosphorus from fertilizer used on farms and ranches in the Kissimmee River Basin, which forms the headwaters of the Everglades and drains into Lake Okeechobee, which in turn reaches the coasts through rivers and man-made canals.
