An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
Kelp forests provide important habitats for many fish species, sea otters and sea urchins. Directly and indirectly, marine coastal ecosystems provide vast arrays of ecosystem services for humans, such as cycling nutrients and elements, and purifying water by filtering pollutants. They sequester carbon as a cushion against climate change.
Major issues of concern include marine pollution and water quality, kelp harvesting and fisheries, invasive species, [8] and climate change. [75] The most pressing threat to kelp forest preservation may be the overfishing of coastal ecosystems, which by removing higher trophic levels facilitates their shift to depauperate urchin barrens.

Sep. 22—Maine is one of the first states to consider the carbon storage potential of seaweed in its carbon budget, a biennial accounting of the balance between locally produced greenhouse gas ...
A potential threat that may arise is loss of habitat due to climate change and its resulting consequences such as ocean acidification and pollution, as well as destruction and/or massive die-offs of kelp forests. This poses a threat because this species depends on dense canopies of kelp for protection from predators and for reproduction.
Seaweed farming is a carbon negative crop, with a high potential for climate change mitigation. [7] [8] The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate recommends "further research attention" as a mitigation tactic. [9] World Wildlife Fund, Oceans 2050, and The Nature Conservancy publicly support expanded seaweed ...
[90] [91] Marine forest habitat is beneficial for many fish species, [92] and the kelp is a renewable resource for food, animal feed, [93] medicines [94] and various other commercial products. [95] [96] It is also a powerful tool for carbon fixation. [90] [97] [98] The upwelling can be powered by renewable energy on location.
Seagrasses store more than twice as much carbon from planet-warming carbon dioxide (CO2) per square mile than forests do on land, according to a 2012 study. The plants also help support fisheries ...
