Seaweed is a hot solution for mitigating climate change. Can this carbon-absorbing powerhouse really help?
Seaweed is having a moment. I’ve been working on seaweed for 40 years, and I’ve never seen so many headlines about how seaweed can save the planet.
I can understand why. The need to save the planet is more pressing than ever. We must now dramatically reduce greenhouse gas emissions and, at the same time, increase the planet’s capacity to remove carbon dioxide (CO2) from the atmosphere to prevent even more catastrophic impacts of global warming.
