With over a million dams and barriers blocking Europe's rivers, freshwater migratory fish are unable to swim to their breeding grounds to mate, and are going extinct as a result. In 2022, European institutions are deciding on the EU Nature Restoration Law, a critical policy calling for the restoration of 178,000km of rivers through the removal of obsolete barriers and restoration of flood planes. But to seize the opportunity, WWF needed to grab attention and get policymakers to give a dam’ about the plight of freshwater migratory fish... who don't exactly have the cute factor. This video is how we engaged EU policy makers on the issue by talking about fish sex... yes, you read that right.
