About World Reef Day
World Reef Day is observed annually on June 1 as an awareness day focused on reefs and the pressures affecting them.
The official World Reef Day toolkit says the day was founded by Raw Elements USA and identifies 2021 as its third year, placing the first annual observance in 2019.
Why World Reef Day matters
The day is a platform for learning about reef ecosystems and supporting responsible conservation work.
Environmental outcomes are complex; an awareness campaign should not imply that one consumer action alone can restore reefs or replace broader scientific, community and policy work.

The 2021 toolkit calls that edition the third World Reef Day, supporting a 2019 first annual observance on June 1.
