Which of the following is the most likely effect of urban sprawl? A. less destruction of natural habitats B. increased shortages of water and other resources C. decreased city temperatures in summer months D. less vehicle and factory emissions

Answers

Well, urban sprawl is just another term for urbanization, the spreading of towns and cities, and basically the disappearance of rural areas as well as nature. So, having that in mind, it would appear that urban sprawl is a negative thing, meaning the correct answer is increased shortages of water and other resources. The more cities grow, the more resources people will need to keep them advanced and modern, which means that soon enough, there will be no more resources for them to use.
