Soil erosion is caused by water and wind due to three major factors :
- Deforestation - due to increasing population and increasing industrialisation.
- Overgrazing - by large animal populations has destroyed vegetation and result in barren land.
- Poor Farming Method - ploughing, loosens the soil and destroys its natural resources.
