From the forests below the sea comes our greatest ally in making this innovation: Seaweed grows quickly, and needs no freshwater, land or fertiliser. It captures carbon and makes the surrounding waters less acidic. Seaweed forests are biodiverse, and can even filter out pollution from human activities. The more we grow of it, the better the effect.
And the best part: worms, fungi and microbes love it. Instead of toxic waste, our containers become food for other living organisms.
