What eats sargassum that could integrate seaweed into its food supply?

“the high concentration of heavy metals, arsenic, and salt tends to restrict high-scale implementation before treatment”

Crap.

“More recent research has also investigated the applications of Sargassum in bioremediation and carbon sequestration because it has a high carbon/nitrogen ratio and therefore could be used to take away contaminants and sequester atmospheric CO2.”

Okay!

“Nonetheless, the presence of high salt and heavy metals in certain Sargassum biomass requires thorough processing prior to agricultural or industrial use.”

Bah!
