Micro-screen harvesters and other devices can be used to scoop ocean-hypoxic zone nitrogen-phosphate rich algae into holding tanks, and introduce the nutrient rich matter to the Sahara/other desert zones. Soil building processes—including adding fungii to introduce microbes in soil, composting and balancing with peat, clays and minerals (precipitated from bio-fuel production projects which may also be sourced from hypoxic water-zone bio-population-explosions) can utilize the solids and grey-water byproducts of organic-harvest processing. Introduce low-water-consumption xeriscaped plants, and augment with bio-diverse plantings (including succulents-- ice plant, harvesting fruit to prevent invasion of species; dragon fruit and cactus pear, etc); then vegetable, flowering, fruit and other trees—can decrease heat bloom, desiccation, desertification; and can increase pollinator-support, food and water security.
Dead Zones (hypoxia) are large regions of water so low in oxygen that they cannot support most aquatic life. Algae blooms on the surface of waters block the sun’s rays from reaching underwater plants, and even grow on sea weeds and aquatic plants growing near enough to the surface, further reducing the amount of sunlight they receive. Without sunlight, water plants (sea weeds, kelps, large grasses) cannot grow, and provide critical food, habitat, and even oxygen to oceanic and inland waters.
Leftover algae that are not consumed by fish (and that is another problem, since small fish fry, polyps and other small species which consume algae are consumed by the myriad jellyfish which thrive in low-oxygen, algae-rich waters) fall to the bottom of the water-system, where they are decomposed by bacteria which leaves little or no dissolved oxygen for the shellfish and other bottom-dwelling species in the aquatic environment. Burning fossil fuels continues to pump carbon into the atmosphere, further lowering oceanic/aquatic pH, also ideal conditions for incubating algae blooms, jellyfish, and the
Overfishing and the “throw-away” bycatch further threatens the well-being of our oceans and waterways, by depleting needed populations of algae- and jellyfish- eaters, and by adding to the decomposition of aquatic life on ocean and deep-water floors. Whales, dolphins, loggerhead and leatherback marine turtles are caught, and die, each year, in commercial fishing gear, while trawling ocean floors kills the kelps, sea grasses, and shellfish which could help keep the world’s waters clean and oxygenated. With 90% of the ocean’s large fish in decline, jellyfish do not have as many predators as they used to. Meahwhile, Pelagia Noctiluca (“Mauve Stingers” plague the Mediterranean seas by the millions; Nomura’s Jelly Fish (echizen kurage in Japanese), which can grow to over 600 pounds, and other species of jellyfish are thriving in the dying waters of the world.
However, we are not without solutions to diminish, and correct, the poisoning and suffocation of our oceans and waterways. Instead of overfishing depleted fish populations, trawlers can be contracted to scoop up surface algae before they die and fall to the waters’ bottom layers, and to remove the huge infestations of jellyfish which currently clog water-zones, and eat much of the fish eggs and small fry that, if left undisturbed, could better repopulate healthy oceans and waters. Catching, and utilizing jellyfish as food, fuel, or compost is a far better solution than chopping them up in the water, since this only causes the butchered jellyfish to release hundreds, even thousands of polyps, which can mature into additional jellyfish needing to be cleaned up.
While some algae and jellyfish can be processed and eaten (various cultures have dined on healthy species for centuries), or (especially if largely dead/decomposing, therefore inedible masses of algae and jellyfish are collected) treated and processed into methane, compost, and recycled grey-water products in anerobic extractors and micro-digester systems, algae and jellyfish can also be utilized as raw materials for building nutrient-rich soils in sand-based or depleted topsoil systems. Whether processed for direct, super-saturated aquatic application to non-arable soil bases (especially efficient in warm/hot zones where decomposition processes are rapid), or utilized in methane-production (“renewable” fuel, which can be further “cleaned and greened” by solar-heated evaporation processes), the compostable materials from jellyfish and algae population explosions can rebuild terrestrial ecosystems, with the addition of fungi and beneficial microbes, processing worms and other digesters, nitrogen-fixing legumes and other plants, and xeriscaped agriculture.
And waterway and oceanic cleanup can similarly progress, by instituting submerged-rope-farming of kelps (e.g. the red kelp Gracilaria) and other filtration-efficient, bio-remediation water grasses and sea weeds (which remove inorganic nutrients from waters, produce oxygen, and provide food and habitat), and the submerged-rope-and-net farming of clams, mussels, and other bivalves filter organically-bound particles, e-coli, and other microbes which would otherwise contribute to the nutrient-rich, acidified, warm waters which lead to algae blooms, algae death/water-floor decomposition, and the spread of hypoxic waterzones and massive populations of jellyfish.
Since sea weeds and shell fish can provide solid nutritional value to human consumers, industries which invest in such bio-remediation measures can reap profits along with their ocean- and water- cleaning harvests. Methane fuel-producers, grey-water extractors, and compost-processors, similarly, can earn living wages while utilizing the algae and jellyfish infestations which are clogging our waterways, to produce clean energy, reusable water, and arable lands to support terrestrial eco- and agri-systems. Whether small/artisanal-sized operations, or scalable to regional, or global water-cleanup efforts supported by industry, NGO, and government investors in a program of serendipitous benefit to oceans, lands, and the humans running the industries and cleanup efforts, bio-extaction of raw materials, and bio-remediation through kelp, water-grasses, and shell-fish farming can improve the chances of sustainable life for many, if not most, of the globe’s millions of species of Earthlings on our shared, interdependent planet.
