Methane Emissions and Seaweed Solution

The video discusses the significant methane emissions from cows due to pasture land use and explores seaweed as a potential solution to reduce these emissions. Initial experiments showed promising results, with methane emissions reduced by up to 98% in some trials. The video also addresses challenges in seaweed cultivation and other potential solutions like dietary changes and additives. It concludes with the potential impact of these solutions on global warming and the need for government support.
