The study, which was published last month in the journal Communications Earth & Environment, closely analyzed past extinction rates for freshwater animals and plants, then used that information to extrapolate likely future extinction rates. "Our results indicate …
The damage humans are doing to the world is now so great that in some ecosystems the biodiversity loss exceeds the rate of extinction at the time the dinosaurs died out, and the destruction could require millions of years to undo, scientists have said. “We rely on functioning freshwater environments to sustain human health, nutrition and fresh water supply.” The …
