Expert weighs in on what happens when algae dies — and it isn’t pretty

As bad as the massive algae bloom on the Treasure Coast is now, sometime in the coming days or weeks or months, it’s going to die. And when it does, the impact on flora and fauna will make the current disaster look like a tipped bait bucket by comparison.
