Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines.

Detailed explanation-2: -The problems associated with urbanization are: High population density, inadequate infrastructure, lack of affordable housing, flooding, pollution, slum creation, crime, congestion and poverty.

Detailed explanation-3: -Some of the problems of urbanisation are pollution, an increase in the number of slums which are highly unhygienic, traffic congestions and so on. Taking important steps like better urban planning and waste management can go a long way into reducing the problems brought about by urbanisation.

Detailed explanation-4: -Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. Strong city planning will be essential in managing these and other difficulties as the world’s urban areas swell.
