Chesapeake Bay Dead Zones: Causes, Impacts, and Solutions

A few years ago, I got into ultra-low-budget found footage movies. You know the convention. Someone is recording while a disaster or horror is unfolding. Think Blair Witch. This article, coincidentally, also takes place in Maryland. So, imagine that a small town on the Chesapeake Bay’s eastern shore is plagued by mutant parasites, turning the […]
