Hay Festival Hay-on-Wye 2024 runs from 23 May till 2 June.  In this event, Helen Czerski and marine biologist Helen Scales speak to the Festival’s Sustainability Director Andy Fryers about our vast oceans.

Helen Czerski’s The Blue Machine illuminates the murky depths of the ocean engine, examining the messengers, passengers and voyagers that live in it, travel over it, and survive because of it.

Helen Scales’ What the Wild Sea Can Be is an optimistic view of the future of the ocean, looking at how fish populations and giant kelp and seagrass forests are being regenerated and expanded.

Venue: Meadow Stage, 4pm
