Deforestation can be defined as the large-scale removal of trees from forests (or other lands) for the facilitation of human activities.
It is a serious environmental concern since it can result in the loss of biodiversity, damage to natural habitats, disturbances in the water cycle, and soil erosion.
If leads to floods.
Deforestation of sloped lands is often accompanied by landslides, which can be explained by the loss of soil adhesion.
The extent of erosion is amplified by certain natural calamities such as floods ( the plant litter found on forest surfaces helps reduce the amount of soil washed away).
Due to deforestation, the water holding capacity of the soil decreases.
The movement of water through trees into the soil slows down.
The water gets collected on the surface due to rainfall which results in floods.
