The world’s newest (and prize-winning) environmental treaty - protecting our high seas

The world's newest environmental treaty will protect the high seas - those parts of the ocean that belong to no nation. These marine waters extend over about half the planet.

This ambitious treaty recently won the world's most prestigious environmental prize - the Earthshot prize for reviving our oceans.

The prize was accepted on behalf of the treaty by the director of the High Seas Alliance - Rebecca Hubbard.  In this episode, Track Changes hosts Franziska and Murray do a virtual 'trip' to Rio to recreate that well-deserved prize-winning moment at the 2025 Earthshot prizes. And then we chat with Rebecca, who explains how the treaty was developed and what it will do. 

It's an inspiring episode - enjoy!
