Seaweed farming absorbs excess nutrients, sequesters carbon, and boosts biodiversity, while shellfish like oysters and mussels filter water and enhance marine habitats. Unlike traditional industries, IMTA requires no fertilizers, freshwater, or arable land, making it a low-impact, high-benefit solution. MPAs limit human impact, but IMTA restores marine productivity while supporting coastal livelihoods. With some MPAs restricting fishing, IMTA provides alternative jobs and food security, especially for women in seaweed farming. Globally, sustainable aquaculture enhances conservation success, proving that protection and restoration must go hand in hand.
