D-Day beaches invaded by green algae in France's Normandy

Large sections of the beach at Courseulles-sur-Mer in France's Normandy are covered with green algae since late June. The algae come back to this area every year, especially around mid-August.

Bathing has been prohibited because of alleged toxicity of the algae on the Normandy shore of the "Cote de Nacre."

Unlike algae in many other places, the growth of Normandy's algae is not primarily the result of agricultural fertilizer runoff into the sea.

Northerly winds and climate change are the tentative cause of the booming algae in this area.
