Can Seaweed Save the World?

This episode of SciShow is brought to you in partnership with Gates Notes. If you’re a college student, you can head to https://gatesnot.es/3jjPmUe to download a free e-book of “How to Avoid a Climate Disaster” by Bill Gates from October 24-31, 2021.

Although plants are great carbon-removing tools, plant agriculture produces a significant carbon footprint. So, some researchers think we could turn to the oceans (specifically, seaweed) to help reverse some of the effects of climate change.
