Clearing the air: who should do the most to tackle climate change?

In the balmy waters off Queensland’s coast grows a red algae that promises to help rescue the planet.

Whose responsibility is climate change?

Sprinkled into the feed of cows, trials show the super-seaweed can all but eliminate greenhouse gas emissions produced by their burps and flatulence.

But the algae – Asparagopsis taxiformis - has never been farmed at scale. Scuba divers must painstakingly pluck it from the ocean. As research founder Rob Kinley of the CSIRO says, the challenges of commercial production are immense.

“The potential is global ... but the barrier is the supply of seaweed. The scale of that is monstrous,” Kinley said.
