    That was quite an interesting read! Also, TIL that some varieties produce useful amounts of protein -- I'd always thought of seaweed as a convenient wrapper, or seasoning, not as a source of any...

    Every ecosystem and species is different, but it'd be interesting to know if adding a mussel farm changes the analysis at all. If not, that would be a fantastic way to double dip.

    Fakhraee explains that coastal seaweed farms are an extremely effective way to remove CO2 from the atmosphere because these algae sequester carbon at high rates. "This nature-based technology removes CO2 and converts it to biomass, but one of the main challenges discussed is that it is expected that most of the carbon and biomass produced would eventually be used by microbes in the water or in the sediment to produce CO2. That was the main concern, whether these are actually a good way of capturing carbon or not."
