Is algal bloom deadlier than plankton bloom?

Algal blooms can be deadlier than plankton blooms, particularly when they involve harmful algal species that produce toxins, such as cyanobacteria or dinoflagellates. These toxins can lead to fish kills, contaminate drinking water, and pose health risks to humans and wildlife. While plankton blooms can disrupt ecosystems and food webs, they are generally less harmful than toxic algal blooms. The severity of each type of bloom depends on various environmental factors and the specific species involved.
