Daño planetario irreversible: necesitamos actuar
El 19 de enero de 2026, Kaveh Madani, investigador del Instituto de Agua, Medio Ambiente y Salud de la Universidad de las Naciones Unidas, en Canadá, lanzó una advertencia incómoda: la Tierra ya entró en “bancarrota hídrica”, como lo planteó en Water Resources Management. No es una crisis pasajera, sino un agotamiento estructural: el uso sostenido del agua supera la capacidad hidrológica, erosiona el capital hídrico y deja daños sin marcha atrás. De ahí los acuíferos en descenso, glaciares en retroceso y suelos degradados que ya no retienen humedad. No es alarmismo; son umbrales críticos ya cruzados.
TL;DR
- The Earth is in 'water bankruptcy' as usage exceeds hydrological capacity, causing structural depletion of water resources.
- Critical environmental thresholds have been crossed, evidenced by declining aquifers, retreating glaciers, and degraded soils.
- The crisis stems from a lack of sustained decisions, not a lack of diagnoses or potential solutions.
- Climate science indicates record ocean temperatures, accelerating sea-level rise, and persistent glacier mass loss.
- A silent biological crisis shows a nearly 70% reduction in flying insect biomass, endangering the food chain and pollination.
- Colombia, despite its biodiversity, faces environmental degradation through deforestation, pesticide abuse, wetland infilling, and habitat fragmentation.
- Current conservation efforts and development models in Colombia are criticized as insufficient and reactive, prioritizing development over nature.
- Urgent action is needed to restore connectivity, protect watersheds, invest in research, and integrate biodiversity into decision-making.
