What is the impact of urban growth on natural systems?

Urbanisation detoriate the natural systems in class 1 and class 2 towns.

Explanation:

Urbanisation require a vast piece of land for its accommodation so the forests, agricultural lands and the other natural ecosystems were destroyed by the human activities and then they constructs the residential complexes, Industrial sectors, basic amenities and so on. The people who gets accommodated in these areas drain the ground water for their daily usages and Industrial complexes uses these ground water abundantly for their industrial purposes and they also polluted the surface water through sewage waters. Improper urbanisation leads to the slum settlements which is the undesirable byproduct of urbanisation and industrialisation.
