Chic and Swag Friday.

Gulf Dead Zone.
The teal blue area along the Louisiana coastline illustrates a region known as the Dead Zone, an expanse of oxygen-depleted (hypoxic) waters resulting from the delivery of excessive amounts of nitrogen pollution from the Mississippi River. Human activity is largely responsible for the seasonal hypoxia, which now threatens not only the marine ecosystems, but also the livelihoods of the people who rely upon them.
