Dustbowl to Dead Zone?
The Minnesota Pollution Control Agency is developing guidelines to reduce fertilizer runoff into the Mississippi River watershed. Why? It promotes algae growth and creates low-oxygen “dead zones” that can’t support marine life. A dead zone off the mouth of the Mississippi in the Gulf of Mexico is the size of Connecticut. Upstream states want to shrink it by limiting runoff.
Less than a century ago Dorothea Lange documented migrant workers escaping another man-made ecological disaster, the Dust Bowl. How are today’s Gulf State residents affected by the dead zone?
