All Rivers Lead to the Sea: A Battle That Never Quite Gets to the Bottom of Things
Jeanie Finlay’s All Rivers Lead to the Sea powerfully conveys the human suffering caused by the mysterious die-offs of crabs and lobsters along the North-East coast. For Stan Rennie, whose family has worked these waters for generations and who has fished them for more than half a century, the catastrophe threatens both his livelihood and his identity: this is a terrible tragedy and an unmitigated ecological disaster.
Yet the documentary’s central weakness is that it does not investigate the die-offs with sufficient evidentiary rigour. Its emotional force is considerable, but its repeated emphasis on injustice often takes the place of the careful examination needed to establish what happened, why it happened and who might be responsible.
The central question remains: what actually caused the deaths in 2021? Was there a specific culprit, or did government agencies conceal an uncomfortable truth? The available evidence does not justify presenting either possibility as settled fact. Investigations by the Environment Agency, the Centre for Environment, Fisheries and Aquaculture Science and other bodies examined several explanations, including pollution, dredging, sediment disturbance, disease and naturally occurring toxins. Attention focused particularly on pyridine, a chemical detected in some samples and associated with dredged material from the Tees. However, its presence did not conclusively prove that it caused the mass mortality. Other scientific assessments pointed towards an infectious disease, including a condition affecting crustaceans, while acknowledging that the evidence was incomplete and that more than one factor might have been involved.
That uncertainty is important. A failure to establish causation is not the same as proof of a cover-up. Officials may have been defensive, slow to communicate and too ready to dismiss local testimony, but institutional opacity and scientific uncertainty should not automatically be converted into evidence of deliberate concealment. Equally, the absence of a definitive official explanation does not vindicate the authorities. When a community’s livelihood is devastated, agencies have a responsibility to publish their methods, disclose conflicting results and explain why particular theories are accepted or rejected. The suspicion of a cover-up grew partly because that transparency was lacking.
I have a particular affinity with this subject. My great-grandfather was a master mariner working the same stretch of water slightly more south around Cleethorpes during the First World War and losing his life and vessel to a mine explosion. Back in the day fishing was a more prosperous industry but not without its rigours and dangers. The fishing coast is therefore more than a picturesque backdrop or a convenient setting for a contemporary environmental controversy. It represents a long history of labour, risk and intimate knowledge of the sea, alongside the precarious relationship between those who earn their living from it and the forces that threaten their existence. Rennie’s predicament deserves to be taken seriously, not simply as an emblem of industrial neglect, but as the predicament of a man whose working life is inseparable from the waters he knows.
Finlay, herself a Teessider, clearly understands the emotional and cultural significance of this landscape. Rennie’s gruff humour, stoicism and mounting frustration give the film its human centre. His struggle against official equivocation and apparent institutional indifference evokes the familiar David-and-Goliath conflict between local communities and more powerful interests. There is genuine poignancy in watching a man confront not only the destruction of his livelihood but also the limitations imposed by his failing health.
The difficulty lies in the film’s insistence on making its point. Finlay returns repeatedly to the same grievances, accumulating expressions of outrage without always deepening our understanding of what has happened. The resulting narrative feels uneven-handed, its moral sympathies established so firmly that the investigation itself begins to suffer. Industrial pollution, the legacy of past environmental damage and the consequences of post-Brexit development are all pertinent questions, but their significance cannot substitute for establishing precisely what caused the die-offs, who bears responsibility and what evidence might resolve the dispute.
The documentary’s sledgehammer approach is ultimately counterproductive. By labouring its arguments, it risks diminishing the complexity of the very issues it wants us to confront becoming instead another exercise in Tory-bashing and efforts to breath life into a region down in its knees economically in other sectors. The viewer is left with a strong sense of injustice but a less satisfying grasp of its origins and as a result the film loses its much-needed clout. Anger is understandable, even necessary, when livelihoods and fragile ecosystems are at stake; it is not, however, a replacement for scrutiny. A more measured film might have allowed conflicting explanations, uncertainties and uncomfortable questions to emerge, trusting the evidence and Rennie’s experience to carry their own weight.
All Rivers Lead to the Sea is most successful as a portrait of human suffering: it makes Rennie’s grief, anxiety and determination vividly felt, and it honours the community whose livelihood is bound to the sea and precious ecosystem of the North Sea. But it does not establish that a particular company or government department caused the deaths, nor does it prove that officials deliberately covered up the truth. The more defensible conclusion is that the crisis was met with inadequate transparency, contested science and a failure to give affected fishermen convincing answers. Finlay leaves us sharing Rennie’s frustration and sympathy for those affected, but not much wiser about the causes of the crisis, the strength of the competing explanations or how responsibility might finally be established.
The most important new development is that the campaign has won a legal challenge to the dredging licence, giving it a practical result beyond public protest. But the legal victory does not settle the original scientific question. The more interesting next chapter may be whether Rennie’s persistence produces the independent scientific answers that the documentary, for all its indignation, cannot provide.
The outstanding questions for ministers are straightforward: will they publish measurable plans for independent coastal monitoring, ensure the revised dredging licence properly assesses environmental risks, and provide practical help to fishing communities whose stocks and livelihoods have suffered?
No comprehensive Labour-government package addressing the issues of environmental cause or economic assistance has been put in place as of October 2026. The clearest answer to what the government is doing involves some regulatory and monitoring work, but no demonstrated resolution of the original disaster and no verified dedicated compensation programme.
