5 Big Threats to Rivers - EcoWatch

If we needed any more motivation to help save our ailing rivers, it should have come with the findings of a recent study (see attached), which revealed that “Nowhere is the biodiversity crisis more acute than in freshwater ecosystems.”

Rivers, lakes and inland wetlands cover 1% of the Earth but provide homes for 10% of all its species, including one-third of all vertebrates. And many of those species are imperiled — some 27% of the nearly 30,000 freshwater species so far assessed by the IUCN Red List. This includes nearly one-third of all freshwater fish.

How did things get so bad? For some species it’s a single action — like building a dam. But for most, it’s a confluence of factors — an accumulation of harm — that builds for years or decades.
