...widening gyre. There were power lines to worry about; some planes heading into Denver were rerouted. The cable-news anchors called in experts to speculate about how high the balloon might drift, how cold it could get inside, how fast it might fall, the odds Falcon would suffer hypoxia, or worse. But the only thing you could think as you watched, was how frightened that child had to be, how crazed with fear his parents, and how there seemed no way that this could end well.

Indeed, severe hypoxia, as scientists refer to the phenomenon, has been linked to the collapse of fisheries in the Baltic Sea, the Black Sea (which has since recovered) and a lobster fishery in the Kattegat, a patch of the North Sea between Denmark and Sweden. Other headline examples exist as well, but, more often, hypoxic waters have a relatively subtle impact on fish. "Most of the effects of low oxygen on fish stocks are what we call 'sub-lethal,' " says Diaz. "It doesn't kill the fish but stresses them. It affects their growth, it reduces their reproductive output...
...grow even bigger. The Louisiana fishing industry, the second largest in the nation, is already hurting, with shrimp catches falling in the dead zone's wake. The U.S. is not alone in grappling with this aquatic byproduct. As modern, chemically intensive agricultural practices spread around the globe, so does hypoxia; a 2004 U.N. report documents nearly 150 dead zones globally. But none compare to the black hole in the Gulf of Mexico. "This year would be the largest since we've started keeping records," says R. Eugene Turner, a zoologist with LSU who led the modeling effort. "It's definitely...
...July 25, they received safety lectures and physiological training from retired air force and army personnel, covering topics such as motion sickness and hypoxia, or the loss of oxygen...
Sudden Death. The primary cause of this breathing failure remains unclear, though sometimes it appears to be linked with obesity. In any case, drowsiness is only the mildest byproduct. The disorder can lead to hypoxia (low blood oxygen), hypertension (high blood pressure), heart disease and in some cases sudden death. Nor is it easily treatable. Conventional sleeping pills can actually worsen the problem by increasing the breathing difficulty. Removing the tonsils and adenoids to make a larger breathing passage seems to work only in children. Shedding weight makes little difference. Jokes the still overweight Siegel: "I've lost...
