The University of Valencia is part of the One Health platform, ‪@PlataformaOneHealth‬ , a single health. Concept based on the fact that human welfare of animals and ecosystems is intimately linked. Climate change, biodiversity loss or antibiotic resistance will affect us at all levels and we need to address the study of these threats and their solutions in a comprehensive way. Because we are not talking about future threats. Human activity has already changed our planet. In Valencia, we are still suffering the consequences of the October 29, 2024 dana, which not only meant the loss that could have been avoided 229 human lives. It also profoundly affected our ecosystems. Therefore, the university immediately launched volunteer actions to help residents of the affected areas and from the faculty of biological sciences actions were carried out for the cleaning the Parc Natural de l'Albufera. The application of the One Health approach is key to achieving public health management, in line with the globalized world and its health challenges. Because union drives, collaboration transforms.
