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 ...
Seaweed farming or kelp farming is the practice of cultivating and harvesting seaweed. In its simplest form farmers gather from natural beds, while at the other extreme farmers fully control the crop's life cycle .
Kelp have had to adapt dispersal methods that can make successful use of ocean currents. Buoyancy of certain kelp structures allows for species to disperse with the flow of water. [21] Certain kelp form kelp rafts, which can travel great distances away from the source population and colonize other areas.
Catastrophic storms can remove surface kelp canopies through wave activity, but usually leave understory kelps intact; they can also remove urchins when little spatial refuge is available. [ 42 ] [ 48 ] Interspersed canopy clearings create a seascape mosaic where sunlight penetrates deeper into the kelp forest and species that are normally ...
In ideal conditions, giant kelp (Macrocystis spp.) can grow as much as 30-60 centimetres vertically per day. Some species such as Nereocystis are annual while others like Eisenia are perennial , living for more than 20 years. [ 53 ]
Kelp farming has the potential to fortify the planet against a changing climate and also creates a regenerative industry led by Native peoples and communities. Reclaiming Native Knowledges Through ...
Third Eye Blind’s singer, Stephan Jenkins, spoke to SPIN about environmental conservation, reducing plastic waste, and, most particularly, about the importance of reforesting California’s ...
It can reach 60 m (200 ft) in length and grow as rapidly as 50 cm (20 in) a day. [51] According to one study, covering 9% of the world's oceans with kelp forests could produce "sufficient biomethane to replace all of today's needs in fossil fuel energy, while removing 53 billion tons of CO 2 per year from the atmosphere, restoring pre ...
