Final answer:
One of Mexico City's significant technological challenges is sinking land, caused by the overextraction of groundwater, leading to infrastructure damage.
Step-by-step explanation:
Today, one of Mexico City's greatest technological challenges is the sinking land due to excessive withdrawal of water from underground aquifers. Fresh water is scarce and the city relies heavily on water piped from remote sources. Leakage, poor infrastructure maintenance, and the sheer volume of water drawn contribute not only to water loss but also to the ground subsidence affecting the city's infrastructure. The demand for resources exceeds supply, exacerbated by a growing population due to rural-to-urban migration and limited agricultural capacity. Solutions such as using technology to improve resource utilizations, changing behaviors to reduce consumption, and distributing resources more equitably are needed to address these issues.
