Gulf of Mexico “Dead Zone” Larger Than Ever and Growing

If you enjoy breathing as much as I do, this story should be cause for concern. 

Toxins spilling into the Gulf of Mexico from the swollen Mississippi are choking off the water’s oxygen at a record pace this spring, leaving a larger than ever oceanic “dead zone” of lifeless water. 

The toxins — primarily agricultural chemicals such as nitrogen fertilizers and pesticides, as well as automobile exhaust and sewage runoff – are killing tiny zoo- and phytoplankton (the little critters who supply about 70% of the earth’s oxygen), and driving away larger sea life.

According to a PBS report, this year’s dead zone, already “the largest ever,” is the size of the state of New Jersey and threatens further harm to the already distressed Gulf wildlife and economy:

Flooding could cause further injury to fisheries in the northern Gulf of Mexico, already reeling from last year’s oil spill, Rabalais said. Dead zones alter the habitat for crab, shrimp, fish and lobster, often forcing them to shallow areas. This includes catchable seafood, like shrimp and snapper, which are vital to the area’s fisheries.

Dead zones are not new to our world’s oceans and river basins, nor are they limited to the Gulf. NASA tracks dead zones in Chesapeake Bay, the Pacific Northwestern coast, the Baltic Sea (which has recently been dubbed “The Suffocating Sea”) and the Yangtzee River — just to name a few of the over 150 known areas of apoxia in the earth’s waters. In fact, dead zone occurences have doubled in the last decade as the earth’s population and the disposal of toxic wastes rise.

This is so outrageous...I also wonder how long, and who, will clean up this mess

Vivianne Mosca-Clark

We all need to help with out planet getting better.
There are thousands of jobs out there helping to clean up environment.
Farming organically is the start for the farm up plastic will help provide jobs, for cleaning up the ocean from plastic garbage.... we need to stop coal for energy....Plant trees bushes and grasses and other smaller plants to bring back out forests. Watch how we use our water.
There are many ways we all can contribute to cleaning up and saving our planet. Our home.

This should have been expected. With the massive amounts of water flushing out the Mississippi drainage area, these floods are cleaning the farm lands but moving the agricultural poisons into the Gulf.

aaargh! nitrogen fertilizers, pesticides, automobile emissions, sewerage runoff - all preventable! surely we can do better...

Its Been over a year since the B.P spill and Im amazed how fast we forget! Can you with good conscience fill up at a B.P. filling station? Apparently many people can. I hate them forever plus another forever, and when I pass one I make the sign of a cross ,as if Im shunning them , kind of like a Vampire, a disgusting creature that sucked all the life out of the Gulf of Mexico and left us with a dead and suffering ecosystem. They haven't paid anywhere near what they owe us===Lets balance our financial crisis and get the billions they owe us that is a very good place to start. They are currently trying to buy the land where the B.L.M is they are one of the reasons are wild horses are perishing ===they want to put an underground pipeline where our horses live, and destroy the horse population ==People wake up THE SKY IS FALLING!
