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.
Deforestation leads to Ploughing of land
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.
