Is pollution in England’s rivers really getting worse? There’s more good news than you might think | Michelle Jackson

River wildlife is on the up and there’s little evidence that storm overflows are being used more often. But protest is still vital

Public outrage over river pollution has been heartening to see. Over the past few years, stories about sewage contamination in rivers have captured public attention, and prompted campaigns and protests, such as the forthcoming River Action UK march for clean water on 26 October in London. It is important to protect our rivers because they are biodiversity hotspots and essential for human health. However, as a freshwater ecologist, I know there is more nuance to the story than you may have been led to believe. From my perspective, there is some good news when it comes to our rivers. I would even say that some rivers in England are in the best state they have been in for hundreds of years.

Many rivers in England are polluted, but we need to recognise that this is not an emerging issue but a much longer-standing one that has been largely ignored by the media and politicians for decades. Much of the recent furore over pollution has to do with increased awareness, rather than a sudden increase in pollution itself. It’s only by understanding how these ecosystems have changed over time and reflecting on previous successes that we can make real progress.
