Did you know dams are actually blocking fish like salmon and eels from making their epic journeys? A massive global study just revealed that these structures are shrinking fish populations and even messing with their genetics. Even those fancy fish ladders aren’t enough! The wild part? When these fish struggle, it impacts everything from local jobs to water quality. Some places are tearing down dams or getting creative with wildlife crossings. Maybe it’s time to rethink how we build around rivers! #WildlifeWednesday #EcoNews #RiverLife #Science
