The tenth annual day of the Más Río Menos Basura initiative once again highlighted the level of pollution affecting the Paraná River. In different points of the Rosario coast, volunteers collected 72 bags of waste that filled five containers, showing a concerning panorama for environmental organizations.
The activity took place around the Aquarium, Costa Alta, the Municipal Camping, and the Rambla Catalunya, areas where waste generated by tourism, commercial activity, and the lack of effective controls accumulate. Plastics dominated the scene, along with cigarette butts, wrappers, and styrofoam.
The operation gathered about 70 people and concluded with a bittersweet balance: a decade of sustained work, but a waste management system that, according to organizations, continues to fall short of providing sufficient responses.
More organizations, more collection, same problem
The initiative was joined by environmental collectives, neighborhood groups, and educational entities, in a joint effort that ended with the recovery of hundreds of contaminating elements. Among the predominant waste were bottles, caps, cigarette butts, and straws, the latter banned by municipal ordinance since 2020.
The detailed classification showed the magnitude of the problem: hundreds of wrappers, disposable cups, plastic utensils, and pieces of styrofoam. The persistence of these materials evidences the lack of oversight in areas with high gastronomic and recreational activity.
For the organizations, the proliferation of disposable waste persists despite the multiplication of cleaning campaigns. They claim that the situation requires firmer policies and permanent controls to prevent the degradation of the riparian ecosystem.
Pollution in the Paraná River: an impact that deepens
The Paraná carries increasing levels of pollution associated with the massive use of plastics, lack of adequate infrastructure, and the dispersion of waste on its shores. The combination of urban waste, tourist activity, and poor waste management causes the accumulation of materials that take decades to degrade.
The impact is direct on fish, birds, and species that depend on the wetland. The small plastics are ingested by the fauna, and the larger elements get trapped in roots and water hyacinths, altering the ecosystem balance.
The situation also affects riparian communities, which live with dirty beaches, unpleasant odors, and loss of environmental quality. Without an integral system of sanitation and control, volunteer days only temporarily alleviate a structural problem.
Ten years of citizen efforts: achievements and limits
The Más Río Menos Basura project celebrated a decade of mobilizing volunteers and highlighting the shortcomings of the urban management system. Over the years, its members have documented the constant presence of prohibited waste and the lack of compliance with current regulations.
The organizations emphasize that, despite social commitment, each day reveals a coast saturated with disposable items. For them, the problem requires more than voluntary campaigns: it demands state capacity, investment, and policies that discourage the use of unnecessary plastics.
The anniversary included a musical closing in tribute to the river and the wetlands, a symbolic gesture to remember the cultural and environmental importance of the Paraná. However, the message remains clear: pollution continues to advance.
Towards a cleaner and more sustainable management of the river
The case of Rosario reflects a widespread problem throughout the Paraná basin. The combination of household waste, industrial waste, and plastic materials threatens its biodiversity and reduces water quality.
Specialists point out that transformation requires measures such as constant oversight, reduction of disposables, expansion of differentiated management points, and sustained environmental education. Without these elements, voluntary interventions can only partially mitigate the damage.
The tenth edition of Más Río Menos Basura raises a key question again: how much more can the Paraná absorb before irreversibly losing its balance? As long as there is no profound change in waste management, the answer will remain uncertain.
