Isabel Losada and Sumit Paul-Choudhury talk to Martin Wright

Environmental Optimism

Hay Festival 2025, 

If you think the outlook is bleak, come and hear some much-needed new perspective on our prospects as Isabel Losada and Sumit Paul-Choudhury discuss their good vibes with Director of Positive News Martin Wright.

In The Joyful Environmentalist Losada gets right on with the solutions. Looking for every single way we can take care of the planet, she addresses how we live and work, travel, shop, eat, drink, dress, vote, play, volunteer, bank – everything. She advocates doing this wholeheartedly, energetically and joyfully, until we’re all fully equipped to be part of the pollution solution.

Astrophysicist-turned-journalist Sumit Paul-Choudhury’s The Bright Side is a deep dive into the power and science of optimism. Irrational though it might seem, optimism is central to the human psyche: without it we would never have survived the unpredictable and often hostile world we evolved into – and it may have lessons for us yet.
