The presence of artificial light can enhance the proliferation of harmful algal blooms

Communities around the world who want to manage toxic algae and cyanobacteria flowers already know that nutritional contamination must be controlled. But now they seem to have another factor of worry: too much artificial light.

“In urbanized areas where there may be problems with nutritional pollution, there are light pollution,” he says. Hans Peter Grossart at the Leibniz Institute of Freshwater Ecology and Inland Fisheries in Germany. “That’s probably because the combination of both causes cyanobacteria to bloom.”
