Rivers, lakes and wetlands take up less than 1% of Earth's surface, yet sustain 10% of all known species — more biodiversity per square meter than any ocean or forest.

Healthy, aren't just vital arteries for ecosystems and communities. They're irreplaceable. On this International Day for Biological Diversity, join us in defending them. 🌊
