Seaweed ‘forests’ can help fight climate change

As the Amazon burns, there’s growing interest in cultivating forests that absorb planet-warming carbon emissions, but that are fireproof.

That’s because these forests are underwater.

An increasing body of research is documenting the potential of seaweed farming to counter climate change as deforestation decimates rainforests and other crucial carbon sinks. Fast-growing oceanic jungles of kelp and other macroalgae are highly efficient at storing carbon. Seaweed also ameliorates acidification, deoxygenation, and other marine impacts of global warming that threaten the biodiversity of the seas and the source of food and livelihoods for hundreds of millions of people…
