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.
A dune with a steeper slope is likely to erode faster because it is more susceptible to wind and water erosion. Additionally, dunes located in areas with high winds or strong water currents will erode more quickly than dunes in calmer environments.

Sand Dunes erode over time usually, however, in the desert it is possible for sand from one dune to be blown off and form another dune. Over time that single dune could "migrate" in a way. Sand dunes on the beach however usually just erode over time, they do not usually move.
Sand dunes are continuously changing due to wind moving the sand around. The appearance of an area covered with sand dunes might remain similar for very long periods of time but the details can well have changed considerably.
Sand dunes are not a permanent feature. They erode as the wind changes. If you want to stop one from eroding you would need to cap it with concrete or stabilize it with groundcover. You could also erect a wind barrier like a snow fence.
Endangered seabirds live in the dunes breeding their young. When people go in the dunes the scare the birds litter smash their eggs.
Sand dunes slow down erosion by acting as natural barriers that absorb the impact of wind and water, reducing their ability to erode the surrounding landscape. The dune's shape and vegetation help stabilize the sand, making it less susceptible to erosion. Additionally, dunes trap sediment, preventing it from being carried away by wind or water.
Planting grass and other seaside vegetation will slow erosion. The roots help to bind the sand together making it more difficult for wind and rain to erode the dunes.
Sand dunes can last for decades to thousands of years, depending on environmental conditions and human activity. Their longevity is influenced by factors like wind patterns, vegetation, and the availability of sand. In stable environments with minimal disturbance, dunes can persist for long periods, while in dynamic areas, they may shift or erode more quickly. Ultimately, the lifespan of a sand dune is highly variable and context-dependent.
