From New Scientist:
NORTH America's freshwater fish are in trouble - and we should have seen it coming.
A report commissioned by the American Fisheries Society has warned that the number of North American freshwater species in danger of extinction in at least part of their range has nearly doubled since 1989. As well as this, 33 per cent of fish have seen their conservation status grow more dire, while only 6 per cent have seen an improvement.
Interestingly, this isn't because of overfishing (though that's a major problem with the saltwater fish populations):
Habitat loss due to humanity's growing thirst for water is the root cause of the problem, says Noel Burkhead from the US Geological Survey in Gainesville, Florida, and one of the report's lead authors.
