Black spots are Dead Zone locations
“Dead zones” are on the rise, says a new study that identified stark growth in the number of coastal areas where the water has too little oxygen to sustain marine life.
There are now more than 400 known dead zones in coastal waters worldwide, compared to 305 in the 1990s, according to study author Robert Diaz of the Virginia Institute of Marine Science.
Those numbers are up from 162 in the 1980s, 87 in the 1970s, and 49 in the 1960s, Diaz said. In the 1910s, four dead zones had been identified.
Diaz and co-author Rutger Rosenberg, of the University of Gothenburg in Sweden, said in a press release that dead zones are now “the key stressor on marine ecosystems” and “rank with overfishing, habitat loss, and harmful algal blooms as global environmental problems.”
Dead zones occur when excess nutrients—usually nitrogen and phosphorus—from agriculture or the burning of fossil fuels seep into the water system and fertilize blooms of algae along the coast.
Lousy agricultural practices and agribusiness greed have combined over decades to bring us to this latest node of irresponsibility and ignorance. The latter being the usual excuse for unwillingness to accept responsibility.
