 Cyanobacteria, also known as blue-green algae, are a type of bacterium that can form harmful blooms in lakes, rivers, and other bodies of water. These blooms can cause a variety of problems, such as depleting oxygen levels, outcompeting beneficial species, and releasing toxic compounds. Global warming has been linked to increased growth rates and blooming potential of cyanobacteria, making them more prevalent and difficult to manage. To combat this problem, strategies must be developed that reduce both nitrogen and phosphorus inputs into the waterways, while also being adaptable to climate change. Additionally, physical, chemical, and biological methods must be used to reduce the presence of cyanobacteria. This article was authored by Hans W. Parle.
