Man-Made "Dead Zone" In Gulf of Mexico the Size of Connecticut
Taco Cowboy writes Somewhere in the Gulf of Mexico there is a man-made "Dead Zone" the size of the State of Connecticut. Inside that "Dead Zone" the water contains no oxygen, or too little to support normal marine life, especially the bottom dwelling fish and shrimps. The "Dead Zone" measures about 5,000 square miles (13,000 square kilometers) [and] is caused by excess nutrient runoff from farms along the Mississippi River, which empties into the Gulf. The excess nutrients feed algae growth, which consumes oxygen when it works its way to the Gulf bottom. The Gulf dead zone, which fluctuates in size but measured 5,052 square miles this summer, is exceeded only by a similar zone in the Baltic Sea around Finland. The number of dead zones worldwide currently totals more than 550 and has been increasing for decades.
It is a life opportunity area. Give it a chance.
This has been going on for a long time. It's due to drainage of basically the Great Plains out into the Gulf. Lots of fixed nitrogen from fertilizers in that these days. That nitrogen stimulates a variety of organisms that also use oxygen. Which there really isn't all that much of in water.
The only way you are going to stop it is to find a different method of raising food for the world. Hint: current organic methods doesn't do it - too labor intensive and yields suffer.
Or you could have less people.

To put this in perspective, 5,000 sq. mi. is a square about 71 miles on a side. Compare this to the total area of the Gulf (615,000 sq. mi) and you'll see this "dead zone" occupies just 0.8% of the Gulf. Is this something that needs addressing? Absolutely. But it's not some horrific cauldron of death like the headline tries to make it out to be.

Damn you, Finns.
" Inside that "Dead Zone" the water contain no oxygen"
Step 1. Find Connecticut-sized container
Step 2. Something something
Step 3. Profit.
Pretending this is my office full of bitter coworkers..
Now if we could only move it TO Connecticut, we could kill two birds with one stone!

We already know about it; it's called Congress.

Calm down. It's been worked out for your viewing pleasure.
Faster! Faster! Faster would be better!
Don't forget: We also hate the poor and minorities too. We want to see them all die so that there is nothing left in this universe but a few rich white men with no earth (because as you yourself state, we hate that too.)
(Disclaimer: I'm not a Republican, but I typically get lumped with them because most people can't see beyond simple left and right.)
It has been known for a long time now that this has *nothing* to do with nitrogen. Nitrogen is never the limiting factor for algae growth. Neither is potassium. So, you have one major fertilizer to guess - yes, it is phosphorus.
Phosphorus runoff is *the* reason for dead-zones and algae blooms. Stop phosphorus runoff, and you fix one of the major problems we have today that not only affects The Gulf, but many of the sweet water lakes too.

Wrong on both points.
1. You do not have to stop using fertilizer if you prevent runoff from getting into rivers and lakes in sufficient quantities to cause problems. This means less ditches, more wetlands, and stop of draining wetlands to get substandard farmland.
2. If people had nothing but organic farming, we would certainly not run out of food. Even if yields were 50% lower (and they would not be), there would still be plenty of plant food to eat. Maybe meat would be more expensive and people would start only eating meat once a week, like 100+ years ago, but there certainly would be enough food to go around.
Secondly, even 100% pure organic farming using natural fertilizer does not solve the problem of phosphorus runoff.
That kind of percentage is a bit misleading. The awkward bit about dead zones is that they occur along the coast in exactly the kind of spots that would otherwise be good for supporting marine life ( a lot of open ocean tends to be nutrient-depleted and middling lifeless... coastal areas have a lot more going for them; the stuff washed out of rivers is a great food source normally).
