Answer:
An unintended consequence of urban growth is that the cities create their own microclimates and produce large amounts of solid waste, photochemical smog, and sewage.
Step-by-step explanation:
The first option is correct because none of those things have been intended when the urban growth occurred, and unfortunately they have all happened, and just that but have had a big negative impact, both on the environment and human health.
The second option is not correct because it is not something that the cities have done, nor had it as a purpose.
The third option is not correct because no group of people has been put in a situation to be deprived of certain resources.
The fourth option is not correct because the cities are economic power-houses, and even though they do not produce the raw materials, they do manufacture and have the power to bring in everything they need.
