Hear from the community

I support The Tide for my family. We live near the sea and I’m a seasonal saltwater swimmer. The health of the ocean is critical for future generations.
Donna D
Tide member from the UK
I give monthly because I want to do something concrete for our planet’s future. It’s easy to forget that we have a responsibility as wardens of Earth.
Ricardo L
Tide member from Italy
I love reading the inspiring stories during my morning coffee and always look forward to the email outlining the projects my contribution has supported.
Cassie G
Tide member from Canada
Following SeaLegacy on Instagram has really opened my eyes to the urgency of this work. As a student I give what I can and it’s great to know that 100% is supporting solutions.

Now is the time to act. Together, we can protect the ocean, stem climate change, and help build a more just, equitable planet.
