How do people erode the dunes?

People erode dunes primarily through activities such as walking, off-road vehicle use, and development. When individuals traverse sandy areas, the foot traffic compacts the soil and disrupts vegetation, which is crucial for stabilizing the dunes. Additionally, construction and urbanization can lead to the removal of protective plant life, making dunes more susceptible to wind and water erosion. Without proper management and conservation efforts, these activities can significantly degrade dune ecosystems.
