In this episode, Katie discusses the impact Raffael Jovine is having on the world as Co-Founder and Chief Scientist at Brilliant Planet - a UK-based research and development company that uses algae to remove carbon dioxide from the atmosphere.

Raffael talks Katie through the effectiveness of the work Brilliant Planet are doing in locations around the world, including Morocco, South Africa and Oman.

The pair discuss the impact the work is having not just on the environment, but also the communities around where the work is based - with many direct and indirect jobs created through the introduction of Brilliant Planet's work. Raffael emphasises the need for their work to not only be sustainable for the environment, but also from a social and community perspective, with many individuals involved in the process.

Raffael reflects on the impact he and Brilliant Planet have had on the world so far, and where he feels they're headed as their work continues.
