Natural seaweeds deplete

dissolved oxygen in the ocean and therefore damage the blue economy by killing

fish stocks.

.      

Seaweed is only useful

as decorative aquarium plants and has no economic or ecological significance.

Seaweeds support

sustainable livelihoods, enhance marine biodiversity, sequester carbon, protect

coastlines, and provide food, fertilizer, and bioenergy products.

Seaweed farming is

purely a land-based agricultural activity with no connection to marine

ecosystems or carbon cycling.

Seaweed farming only

benefits deep-ocean ecosystems and has no relevance to coastal communities or

urban blue-green infrastructure.
