seaweed farming

The Pew Charitable Trusts highlights sustainable seaweed farming as an opportunity for coastal communities, arguing it can support local livelihoods, strengthen economies, and improve marine health. Seaweed requires no freshwater, fertiliser, or feed, making it a low-impact crop with growing commercial demand for food, fertiliser, and other products. Supporters say expanding the industry responsibly could deliver environmental and economic benefits at once, though care is needed to avoid ecological harm.
