Who We Are

Our work begins where rivers meet the sky and ends where groundwater feeds the soil. We use science to protect it all.

This work is possible because of community members like you. Together we can turn the tide.

Who We Are

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We monitor trends so nature can recover.

• Habitat restoration to revive ecosystems

The water that flows through you connects you to 7 billion people — and billions more organisms. Join the fight.

Who We Are

'Thirty years ago, this river was dying. Thanks to this organization, children can swim safely. I watch the difference daily.' — Professor Chen

We believe that nature can heal if we give it the chance. Our growing coalition shows that grassroots action works.
