Huntington, West Virginia
Ever since 2010, Huntington has lost 6% of its population, which isn’t surprising. The city was a thriving coal town back in the 1900s, but it has since come across some hard times. Dealing with a huge opioid crisis, the city has been named America’s overdose capital. The city also reported as the unhealthiest city in the U.S. back in 2008.

This city has a massive issue with flooding, thanks to high tides. They’re predicting that their 2,780 septic tanks will soon stop functioning properly due to the rising sea levels. This means that water will end up in places it shouldn’t be.
