B
From May to November, six beach houses have fallen down in North Carolina's Outer Banks—a troubling sign of how erosion(侵蚀) continues to take a toll on the state's coastal villages.
The most recent collapse(倒塌) happened between last Thursday and Friday after a storm caused powerful waves along Rodanthe. The house was empty, and officials have been in contact with the house owner. Less than a mile away, three other houses had fallen down in September. Since 2020, a total of 11 houses in the area have been washed away into the ocean.

Cape Hatteras National Seashore said strong winds, large waves, as well as rising sea levels—which were caused by climate change—were causing beaches on the Outer Banks to wash away. "Many buildings close to the beach in Rodanthe are either partially or fully covered with ocean water on a regular basis," the Seashore said.
It's a problem faced by coastal communities around the country. In North Carolina, over 750 houses along the state's beaches are considered in danger from erosion, according to an August report released by the state's Department of Environmental Quality and Cape Hatteras National Seashore. Erosion in these coastal villages affects tourism and destroys sea turtles' home, and when houses fall down, it leaves ruins(废墟). The situation is expected to worsen as a result of rising sea levels and more coastal storms.
National Seashore officials have warned owners of unsafe houses to either strengthen their home's supports or move to a safer location if possible.
