Seaweed! The Humble Organism Fighting Climate Change with Assoc. Prof. Alex Campbell (481)

Marine Ecologist Assoc. Professor Alex Campbell takes us into the wonderful, under-appreciated world of seaweed and makes the case that it might be one of our most powerful allies against climate change!

We dive into seaweed's evolutionary history and the troubling decline now underway: as ocean temperatures rise, marine organisms are shifting toward the poles at a rate of over 60km per decade to escape the heat, with Tasmania's once-thriving giant kelp forests shrinking by a staggering 90% since the 1990s due to devastating changes to their habitat.


But the story isn't all bad news. Seaweed also holds genuine promise as a climate solution - from carbon sequestration and biofuel production, to a renewable alternative to plastic, to livestock feed additives that can dramatically cut methane emissions. Alex makes a compelling case for why this humble marine organisms deserves a much bigger role in how we tackle climate change.
