Climate change may be sparking new and bigger "dead zones"
... Scientists are discovering that climate change -- and not just fertilizer from farm use -- may be spurring the emergence of barren underwater landscapes in coastal waters. Expanding dead zones not only spell trouble for biodiversity, but they also threaten the commercial fisheries of many nations... Agricultural runoff sparks many of these die-offs; increased use of nitrogen fertilizers has doubled the number of lifeless pockets every decade since the 1960s, resulting in 405 dead zones now dotting coastlines globally.
But lesser-known wastelands are also emerging -- without nutrient input from farms.
