“Kelp forms whole forests that are supporting so many other species and so it just has this cascading effect on the near-shore ecosystem when you lose your kelp,” Elsmore said. “You’re ...
When the nest is created, it is made with soft red and or brown algae and no hard substances [2]. It is kept well-concealed within the kelp beds. Eggs are either brown or red, due to the color of the yolk. The female lays 400–1200 eggs and spaces them out among the algae nests. They develop very quickly and hatch at around 2 weeks [11].
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.

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 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 ...
It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change. [ 68 ] A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse ...
Giant sun shades, 40-foot-tall air filters, stratospheric sulfur injections: Here are some of the wild and wondrous ways we might save the planet.
Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms [12] and are a source for understanding many ecological processes. Over the last century, they have been the focus of extensive research, particularly in trophic ecology, and continue to provoke important ideas that are relevant beyond this unique ...
