Freshwater landscapes are home to 10% of all known species on Earth but a new IUCN co-authored study reveals 1/4 of freshwater animals at risk of extinction
It is the largest global assessment of freshwater animals on the @IUCNRedList to date

Wetlands provide us with clean water, biodiversity and climate resilience. Yet, we are losing them far too quickly. Protecting and improving the management of these ecosystems is critical for our future.
