Seaweed is largely transported from coastal areas to the open and deep ocean, acting as a permanent storage of carbon biomass within marine sediments. [65] Ocean afforestation is a proposal for farming seaweed for carbon removal. [53] [66] After harvesting seaweed is decomposed into biogas (60% methane and 40% carbon dioxide) in an anaerobic ...

Under this harvest regime, beds can recover their harvested biomass within a year, [42] [43] and no long-term impact of the harvest on the biomass or morphology of A. nodosum has been observed. [44] [45] Several studies have looked at the impact of the harvest on associated species and have found only limited short-term impacts. [46] [47] [48]
Any ecosystem impacts of using seaweed for plant and crop fertilizer are primarily due to how the seaweed is harvested. [36] Large-scale, unsustainable seaweed farming can lead to the displacement and alteration of native habitats due to the presence of farming infrastructure in the water, and day-to-day anthropogenic operations in the area.

Laminaria was harvested for food and 1949 yielded 40.3 metric tons of dry weight. [9] Laminaria need cold water to survive and can only live above 36° N latitude. [citation needed] In 1949, the Chinese started to commercially grow laminaria as a crop. This increased the production of dry weight to 6,200 metric tons.
