11. From Tide to Table: Seaweed Farming's Role in Carbon Capture

Episode produced by Phillipe Edde, Jeanine Fernandes, and Yuying Chen.

This episode explores potential solutions for climate change, focusing particularly on the topic of seaweed farming as an innovative method for carbon sequestration. We are joined by experts in the field, Dr. Lisa Levin and Dr. Thierry Chopin, to delve into the complexities surrounding ocean-based climate interventions (OBCIs) technologies and their implications for climate change mitigation. Climate change is a widely discussed subject and has ignited global concern. Behind the scenes, the emission of greenhouse gases serves as a primary catalyst for this phenomenon. From greenhouse gas emissions to the urgent need for action, we're embarking on a journey to understand how OBCIs, particularly seaweed farming, can help mitigate the rising levels of carbon dioxide in our atmosphere.

We explore both the potential co-benefits of seaweed farming, such as its uses as fertilizer, animal feed, and biofuels, as well the challenges involved in seaweed farming, including nutrient depletion, algal blooms, and disruption of marine ecosystems. We acknowledge that seaweed farming is a pilot strategy, and there are many complexities and uncertainties associated with this method.
