TED: What seaweed and cow burps have to do with climate change | Ermias Kebreab

The video discusses the significant methane emissions from livestock, particularly cows, and explores seaweed as a potential solution to reduce these emissions. Initial experiments showed promising results, with seaweed reducing methane emissions by up to 98% in some trials. The video also covers the nutritional importance of meat and dairy, especially in low-income countries, and the challenges of scaling seaweed production. It concludes with a call for government support to implement these solutions and highlights the potential for seaweed to help mitigate climate change.
