Final answer:
The unplanned growth of a city can result in self-constructed slums, traffic congestion, trash buildup, high crime rates, health issues, and air pollution.
Step-by-step explanation:
The unplanned growth of a city can result in a number of negative consequences. One of the most common results is the development of self-constructed slums and squatter settlements, which lack basic public services such as electricity, running water, and transportation systems. These areas can become overcrowded and lead to problems such as traffic congestion, trash buildup, high crime rates, health issues, and air pollution. Additionally, unplanned growth can lead to other challenges such as overcrowded schools, racial tensions, and a widening economic gap between the rich and the poor.
