How does deforestation affect soil?
Deforestation removes vegetation, which anchors soil in place. Without enough trees, soil is vulnerable to erosion and nutrient loss. The absence of roots causes topsoil to easily wash or blow away, leading to decreased soil quality and increased landslides. It’s estimated that a third of the world’s arable land has been lost to soil erosion and degradation since 1960. Once land is cleared and roots are ripped away, cash crops like coffee and soy are planted which can make erosion worse, since their roots cannot anchor into the soil like those of a tree.
