NASA has created new maps showing the grim reality of marine dead zones. These areas of www.y-e-n.net deep water where oxygen levels are too low for marine life to us cialis survive have grown at a staggering pace since the middle of the 20th century.
The dead zones are created when fertilizer run off from crops makes it into the webstuff.nl ocean, creating massive algae blooms. When the algae dies, it sinks to the bottom where microbes decompose the matter, which consumes oxygen and visit our site generic levitra online pharmacy creates a suffocating environment for marine life.
NASA was able to located the areas where this was occurring by using satellites that detect high concentrations of particulate organic matter. Those high concentrations are a signal of extra fertile areas that lead to dead zones.
The dead zones are mainly located along the coasts of large population centers, with the east coast of the U.S. and the thegracedarlinghotel.com.au coasts of Northern Europe having the largest numbers of these zones.
Since the 1960's, the creation of click here cialis soft gel dead zones has snowballed, with the total amount of area occupied by dead zones now equaling 152,000 square miles and 400 different ecosystems being affected.
