ABSTRACT

Urbanization refers to general increase in population and the amount of industrialization of a settlement. It includes increase in the number and extent of cities. It symbolizes the movement of people from rural to urban areas. Urbanization happens because of the increase in the extent and density of urban areas. Due to uncontrolled urbanization in India, environmental degradation has been occurring very rapidly and causing many problems like land insecurity, worsening water quality, excessive air pollution, noise and the problems of waste disposal. This paper emphasizes on the effect of

[C] IMPACTS ON THE HYDROSPHERE AND WATER RESOURCES
1. Flow of Water into Streams
Natural vegetation and undisturbed soil are replaced with concrete, asphalt, brick, and other impermeable surfaces. This means that, when it rains, water is less likely to be absorbed into the ground and, instead, flows directly into river channels.
2. Flow of Water through Streams
Higher, faster peak flows change streams channels that have evolved over centuries under natural conditions. Flooding can be a major problem as cities grow and stream channels attempt to keep up with these changes.
3. Degraded Water Quality
The water quality has degraded with time due to urbanization that ultimately leads to increased sedimentation there by also increasing the pollutant in run-off. IJREAS Volume 2, Issue 2 (February 2012)

[D] IMPACTS ON THE BIOSPHERE
1. Modification of Habitats
The fertilizers that spread across lawns find its way into water channels where it promotes the growth of plants at the expense of fish. The waste dumped into streams lowers oxygen levels during its decay and cause the die-off of plants and animals.
2. Destruction of Habitats
There is also complete eradication of habitats as an outcome of urbanization and native species are pushed out of cities.
3. Creation of New Habitats
New habitats are also created for some native and non-native species. Cities also create habitats for
