Critical situation facing freshwater biodiversity worldwide
Freshwater ecosystems under threat: A recent study found that 24% of freshwater animal species, including fish, crabs, dragonflies, and others, are at risk of extinction.
Multiple threats: These species face numerous threats, including pollution, dam construction, water extraction, agriculture, invasive species, and climate change.
Fragile ecosystems: Freshwater ecosystems, despite covering a small portion of the planet's surface, support a high diversity of life and are particularly vulnerable to human activities.
Urgent need for conservation: The findings underscore the urgent need for effective conservation measures to protect freshwater ecosystems and the species that depend on them.
