Coastal Bluffs and Shoreline Protection
Coastal development, particularly the construction of seawalls, can harm beaches by blocking the natural sand supply from eroding bluffs, ultimately reducing ecosystem health.
A recent study reveals that natural beaches tend to thrive, with their health scoring double that of armored ones. As noted, "While built to protect the coast, this rock armor could actually degrade beach ecosystems, according to the study."
