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.
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.
As the microscopic plants die and sink to the ocean floor, they feed bacteria, which consume dissolved oxygen from surrounding waters. This limits oxygen availability for bottom-dwelling organisms and the fish that eat them.




What is at work here is a neoconservative, self-fulfilling prophecy in which Russia is turned into an enemy that expands its largely reduced military, and Putin is cast as the new Josef Stalin bogeyman, evoking images of the old Soviet Union.
President Bush seems to be slowly turning the nation's massive surveillance apparatus upon its citizens, and some worry that administration assurances to protect civil liberties are nothing but empty promises.
