Dead Zone Pollutant Grows Despite Decades of Work

Washing off farms and yards, nitrate is largely responsible for the Gulf of Mexico’s infamous “dead zone.” Nitrate and other nutrients from the vast Mississippi River basin funnel into the Gulf, sucking oxygen out of the water and killing almost everything in their path.
