The geography of states and cities all over the world are changing rapidly as concrete structures are gradually occupying vacant lands in large numbers. The drastic rise in population across the globe is leading to increasing demand for residential areas and as a result multistoried buildings and residential apartments are coming up in large numbers. To give spaces to real estate projects, people are even filling up ponds and water bodies and the number of playgrounds is going down. Not only residential apartments but real estate projects have changed the definition of commercial centers too. Modern flashy shopping malls with all kinds of modern facilities are coming up in all developed cities of the world in large numbers to meet the needs of people.
