Read, listen and check your answers. If soil is looked after, it can be used again and again. If it is treated badly, many problems such as desertification can be caused. Soils in mountain and semi-desert areas are most at risk. If too many trees and grasses are removed by people or by animals, the soil becomes poor and is washed away by rain, or blown away by the wind. One-third of the world's land area is at risk of soil erosion and desertification. Wood and charcoal burning destroys forests, removing soil and making land into desert. Desertification can be stopped by expensive tree-planting programmes and better land-management.
