Artificial Light Pollution Linked to Rise in Toxic Algal Blooms

Quick Summary:

• Artificial light pollution, specifically “skyglow” from urban areas, may contribute to the growth of toxic algal blooms such as cyanobacteria.
• Cyanobacteria blooms are often fueled by nutrient pollution; however, researchers now suggest that artificial light could further exacerbate the issue.
• Hans-Peter Grossart from the Leibniz Institute of Freshwater Ecology and Inland Fisheries in Germany highlights concerns about this dual impact: urban light pollution combined with nutrient pollution fostering cyanobacterial blooms.
