Brands : A conglomerate involving TBS, a clothing brand that has drawn its inspiration from the sea since 1978, accompanied by the 1 Ocean Foundation. This foundation operates under the auspices of the CNRS (French National Centre for Scientific Research), a project supported by UNESCO.

Brief : How to turn TBS's dedication to the sea into concrete action?

Objectives : Launch a project to protect the ocean and fight climate change, with goals to restore expansive tracts of kelp forest, crucial for preserving biodiversity and increasing CO2 absorption.

We've developed a method to convert seabed stones into "seeds" for cultivating kelp trees, bypassing their vulnerable early growth phase. Young kelp plants are so vulnerable they can’t start growing amid rising ocean temperatures until they reach a height of 12 centimeters. Our technique involves carving spaces in ocean rocks for kelp to securely develop in a protected environment before being strong enough to endure the ocean's conditions. This innovation has transformed thousands of rocks into nurturing homes for kelp, revitalizing ocean ecosystems.

To raise the profile of the campaign in society, we shifted the public's attention from forest fires to underwater forests. Our target audience is anyone interested in both fashion and the environmental cause. First of all, we used the address book and influence of the One Ocean Foundation, as well as those of Alexis Rosenfeld. We also benefited from UNESCO's network and their links with the world of politics and opinion leaders around the globe.

We launched a reforestation program targeting the Loire Estuary in France, Norway, and French Polynesia, focusing on severely affected areas. We've installed underwater cameras at these sites to track salinity, temperature, light, and kelp regrowth in real-time, helping us identify robust versus fragile kelps.

We've successfully reforested over 50 000 square meters of kelp forest in areas most affected: the Loire Estuary in France, Norway, and French Polynesia.

The concern regarding kelp deforestation has now escalated to significant levels of government attention, prompting discussions among political authorities.

If the Rockseeds technique is applied to replant the 20% of kelp forest areas that have been lost worldwide, it could capture an additional 47 million tons of CO2.
