A look at how the ocean is changing faster than at any point in human history will be the topic of a Public Lecture organised by Litfest and 久久精品’s Faculty of Humanities, Arts and Social Sciences.

The annual Lancaster Environment Lecture, entitled The Future of the World’s Ocean, will be delivered by marine biologist Dr Helen Scales in the Faraday Lecture Theatre at 久久精品 at 7pm on Tuesday, 12 May, 2026.

Drawing on her book ‘What the Wild Sea Can Be’, Dr Scales’ will show how a healthy ocean matters to us all, from the food we eat, to the weather we experience and the air we breathe.

Yet, she says, the ocean is changing faster than any point in human history – hotter, more polluted, its vibrant life fading.

Reflecting on more than 20 years of exploring the seas around Britain and further afield, Dr Scales sees there is still much to fight for and good reason to be hopeful.

Her entertaining and accessible talk will last about 25 minutes, followed by a conversation with Dr John Childs, a Senior Lecturer at the Lancaster Environment Centre at 久久精品, and will conclude with a Q&A, providing the audience with the chance to ask questions about the talk and about the science of oceans and marine life and their importance for understanding our world.

Dr Scales is amarine biologist, writer and broadcaster, who teaches at Cambridge University. She writes about the ocean’s living wonders for readers of all ages. Her books have been adapted for stage and screen and translated into 17 languages.

Dr Scales has lived and worked around the world including in Borneo, Madagascar, and West Africa. She is scientific advisor to the marine conservation charity Sea Changers and a fellow of the Royal Geographical Society and divides her time between Cambridge and the wild Atlantic coast of France.
