Yes, Flint is a city with some problems. But let's remember that there are always other cities with bigger problems, like Timbuktu, as Ransom Riggs points out at mentalfloss.com:
"If things keep going like they’re going, before long Timbuktu is going to be a “deserted” city in more ways than one: desertification, in which sand dunes swallow greener land, is a problem in several countries on the southern fringe of the Sahara. One of the cities most threatened is Timbuktu in Mali, a 1,000-year-old settlement that was a major center of Islamic learning during the 15th and 16th centuries. Several projects are under way to try to 're-green' the land with tree plantings and the like, but some parts of the city are already half buried in sand."
