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.

A welding hammer strapped to her wrist, Joy Hollenback slipped on blue fins and swam into the churning, chilly Pacific surf one fall morning to do her part to save Northern California's vanishing ...
Seaweed farming is a carbon negative crop, with a high potential for climate change mitigation. [8] [9] The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate recommends "further research attention" as a mitigation tactic. [10] World Wildlife Fund, Oceans 2050, and The Nature Conservancy publicly support expanded seaweed ...
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 ...
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].
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.
The Giant kelp marine forests of south east Australia is a community extending from the ocean floor to the ocean surface, on a rocky substrate, and has a ‘forest-like’ structure with many organisms occupying its various layers, including pelagic and demersal fishes, sea birds, turtles and marine mammals in addition to the invertebrate ...
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 ...
