Today, we look at the return of Banksy after a new mural appeared overnight on a building in North London. And we look at why some potato-sized lumps on the seabed could be so valuable. Crowds have gathered in Finsbury Park to see the latest Banksy, a green spray painted tree mural on an empty building. What is its message? And does the artist still have the appeal they once did? Adam speaks with James Peak, the creator of the BBC Radio 4 series, “The Banksy Story.”

Plus, the dispute going on over precious metals found in deepest parts of the ocean. The lumps contain crucial battery minerals including copper and cobalt, but some environmental groups say attempts to collect the materials could damage unique habitats. Adam looks at what’s at stake with oceanographer and co-host of the Radio 4’s “Rare Earth” series, Dr Helen Czerski, and BBC climate editor Justin Rowlatt.
