Every Wednesday and Friday in August we will publish some of our favourite audio long reads of 2025, in case you missed them, with an introduction from the editorial team to explain why we’ve chosen it.

But when so few survive, are we putting them through needless suffering? By Sophie McBain. Read by Chloe Pirrie. Help support our independent journalism at theguardian.com/longreadpod
