Final answer:
Planting vegetation on the beach is a way to decrease erosion and stabilize the soil.
Step-by-step explanation:
One way to decrease the amount of erosion on the beach is by planting vegetation on the beach. Vegetation, such as grasses and trees, can help to stabilize the soil and prevent it from being easily eroded by wind or water. The root systems of plants hold the soil together and reduce the impact of waves and wind on the beach. Additionally, plants create a barrier that helps to trap sand and prevent it from being carried away by the wind.
