Answer 2

$\Large{\underline{\underline{\bf{ LAND\: DEGRADATION}}}}$

Explanation :

Land degradation refers to'the decline in productivity of cultivated land or forest land. Generally, land degradation results from unsuitable and unscientific land use Over-exploitation of land resources and concretisation causes land degradation, landslides, soil erosion and desertification, which are major threats to the environment.

Factors responsible for the degradation of land include excessive exploitation of land, deforestation, clearing fertile land for settlements, slashing and burning the trees for agriculture (jhum), abandoned mining sites and surface mining, toxicity in the landfill, untreated industrial effluents, concretisation, etc.
