HAB (harmful algae bloom)

Algal blooms are large populations of algae, and in most cases are not harmful. However, some algae blooms can produce toxins that harm both fish and humans. Algae blooms are formed due to their environments, usually warm and nutrient filled water. In order to prevent these harmful blooms, scientists try to predict where they will be with satellites. If the pollution that some algae thrive off of was lessened, it would also help to prevent the growth of the blooms. The Long Island Scallop fishery had to be continuously closed due to HABs, and this is just one example of a place effected by Harmful Algae Blooms.
