Étretat, Normandy, France

Étretat, Normandy is known for its iconic coastline and rocky archway by the water. But that coast is quickly eroding due to sea level rise, and over tourism is only making that worse, France24 reported. The increased foot traffic has even created landslides. Local officials also worry about the wastewater treatment facility. It wasn’t made to handle thousands of visitors a day, along with the local population. It had to be shut down for maintenance last year due to overuse, according to France24.
