The initiative, driven by the Sanlúcar Fishermen's Guild, the Salvemos el Guadalquivir Civic Association, Ecologistas en Acción, and Greenpeace, aims to raise awareness about the environmental and economic impact that these discharges could have on the river's estuary.

The organizers are calling on citizens to mobilize against what they consider a significant risk to the Guadalquivir and its surroundings, especially in the final stretch of the estuary. This area is crucial for economic activities such as fishing and tourism, which directly depend on water quality.

Although specific details about the route and schedule of the march have not been released, the organizing entities emphasize the importance of this mobilization. Their goal is to highlight concerns about the potential effects of mining activity in the river basin and demand stricter environmental protection measures.

The Sanlúcar Fishermen's Guild, representing professionals working at the mouth of the Guadalquivir, has repeatedly expressed its concern about any action that could compromise water quality and marine resources, which are essential for their livelihood. Meanwhile, the Salvemos el Guadalquivir Civic Association and the involved environmental organizations advocate for the need to preserve the river as a natural heritage and a source of sustainable economic activity.

The Guadalquivir is one of the most important rivers in Andalusia, and its mouth in Sanlúcar de Barrameda is an environmental and productive enclave of great relevance. The quality of its waters directly influences fishing, aquaculture, and other sectors linked to the coast.

This demonstration is part of a series of actions promoted by citizen and environmental groups in defense of the river. The organizers have requested maximum dissemination of the call to achieve broad social participation, open to residents of Sanlúcar and other municipalities near the Guadalquivir.
