Could the future of global food security be found in the humble jellyfish?

All hail our jellyfish overlords | Episode 6 · 38:29 · Video: Natural History Museum · Watch at the source

In short: As ocean temperatures rise and marine ecosystems face unprecedented stress, scientists are investigating whether jellyfish might become a staple food source. This episode examines the impact of climate change on our seas and explores how humanity might adapt to a shifting underwater landscape.

The ocean is currently undergoing significant transformations, including increased acidity and rising temperatures, which threaten the survival of coral reefs—habitats that support one quarter of all marine species. Experts from organizations like the Reef Renewal Foundation Bonaire, the University of Edinburgh, and the University of British Columbia are analyzing these shifts to understand the long-term consequences for marine life.

Beyond the ecological crisis, the discussion turns to practical adaptation. Researchers and campaigners, including representatives from the Blue Planet Society and Greenpeace, explore potential solutions such as coral reef restoration techniques and the possibility of incorporating jellyfish into human diets as traditional food sources change.
