Our transcription: Problems often arise as the result of special circumstances.
During severe storms, for example, crashing waves can batter coastlines.
Such storms occur only once every few decades, but in the quiet periods in between, people tend to ignore the historical record of erosion and build along the edges of the shore.
To protect the ocean-view homes and hotels that are perched atop sea cliffs and along beaches, seawalls have been erected that reflect the energy of the waves away from the coast and slow down erosion.
However, what may have sounded fairly straight forward in theory has become quite controversial in practice.
Those in favor of seawalls argue that the cliffs must be protected to safeguard the real estate above them.
