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.

Just one example is the giant bull kelp Nereocystis luetkeana, which have evolved to change blade shape in order to increase drag in water and interception of light when exposed to certain environments. Bull kelp are not unique in this adaptation; many kelp species have evolved a genetic plasticity for blade shapes for different water flow ...
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.
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 ...
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 ...
Restoring global forests could sequester 22 times as much carbon as the world emits in a year, according to a scientific study published on Monday, making the case that trees are a key tool in ...
The fly oviposits in dead kelp that washes up on beaches. [8] This is the only place it lays eggs, and it can do so on many species of kelp and seaweed, [9] including species of Laminaria and Fucus. [10] A female fly lays up to five clutches of 80 eggs each. [11] The larvae feed upon the bacteria coating the dead kelp. [9] The life cycle is ...
