Soil erosion causes water pollution. It can also lead to landslides                    . A landslide is
                    moving of loose rocks down a slope of a hill or mountain. This results in the

                    loss of life and property.

                    w      We  need  wood  for  many
                           purposes. To meet the demand

                           of wood, man has been cutting
                           down trees in the forest. The

                           cutting down of all the trees in
                           an area is called deforestation           .
                           It  is  the  major  cause  of  soil

                           erosion.  When  trees  are  cut

                           down, soil becomes loose and
                           is easily carried away.

                    w      Over grazing by animals in a particular area makes the land barren. This

                           too results in soil erosion.
                    w      Ploughing of farmland also loosens the soil. Wind or water can easily

                           carry this loosened soil away.
                    w      Sometimes,  soil  is  left  bare  for  a  long  time  after  harvesting.  This

                           unprotected soil can be easily blown away.

                                                                   soil erosion
                    SOIL CONSERVATION
                    Soil erosion reduces the soil fertility. Therefore, it is important to protect the

                    topsoil from erosion. The term 'conservation' means the steps taken to protect
                    our natural environment. The protection of soil from erosion is called soil

                    conservation.
