Recent assessments reveal alarming statistics regarding freshwater biodiversity. A study conducted by the International Union for Conservation of Nature (IUCN) indicates that nearly 25 per cent of the 23,496 species examined are threatened with extinction. This analysis marks the urgent need for conservation efforts in critical habitats.
Extinction Statistics
The study identified 4,294 species at high risk of extinction, which equates to approximately 18.3 per cent of the total assessed. The majority of these species are found in biodiversity hotspots such as Lake Victoria, Lake Titicaca, Sri Lanka’s wet zone, and India’s Western Ghats. These areas are home to unique species that exist nowhere else on the planet.
Threats
The primary threats to freshwater species include habitat loss and degradation, pollution, overexploitation, invasive species, and climate change. The study serves as a wake-up call for the global community to take urgent action to protect freshwater ecosystems.
