Trees can control and prevent landslides, floods, and coastal typhoons from happening. Trees could be planted across natural disaster-prone areas. Trees help hold the soil down, and their roots soak up water. They can reduce erosion and anchor down topsoil. Even trees' leaves help prevent flooding. When raindrops bounce off them, the water doesn't hit the ground as hard. Forests and individual trees can assist runoff from small storms and more significant disaster events. Forests, particularly on higher and steeper locations like hills, provide bases that drain and delay water and reduce sediment loading. The runoff from storms could also cause soil erosion. The top part of dirt is known as topsoil and is the most fertile ground needed for life. While soil erosion is a natural phenomenon, it is responsible for serious damage and loss to vegetation, agriculture, and property. Therefore, in large quantities, soil erosion can be considered an environmental problem. Over a prolonged period, soil erosion can completely degrade a landscape, decimating a once great and vibrantly lush location. Trees such as mangroves protect shorelines from damaging storm and hurricane winds, waves, and floods.
