Gastronomy, a term often attributed solely to the culinary artistry of chefs, extends far beyond the kitchen. It exists as a vast ecosystem, intricately interwoven with specialized suppliers, diligent fishermen, and dedicated farmers, all deeply rooted in the bounty of nature's offerings. Remarkably, this intricate tapestry is not merely a reflection of nature's unassisted beauty, but also a testament to the efforts aimed at restoring and preserving it.<br><br>Nippon Steel, recognizing the urgency of addressing the nationwide environmental concern known as "rocky-shore denudation", has embarked on a mission to foster the "creation of marine forests". At the heart of this environmental endeavor lies a profound insight into the interconnectedness of our actions and their consequences on the natural world.<br><br>One of the contributing factors to the alarming "rocky-shore" phenomenon is the diminished supply of iron, a vital element for the growth of kelp and seaweed. This scarcity is the outcome of extensive deforestation and upstream development, which have disrupted the flow of iron through rivers. To combat this pressing issue, Nippon Steel pioneered the development of an innovative iron supply unit containing humic substances derived from iron and steel slag, combined with waste wood. This pioneering effort, initiated in 2004, has culminated in the creation of what is aptly termed a "seaweed bed" or a "marine forest".<br><br>Further reinforcing their commitment to scientific exploration, Nippon Steel has established a "Sea Laboratory", a marine environment simulator, situated within the Technical Development Bureau in Futtsu City, Chiba Prefecture. Here, rigorous research endeavors are conducted, aimed at unraveling the potential utility and safety of employing steel slag as a foundation for marine forest construction.<br><br>Central to their eco-friendly initiatives is the formation of iron supply units that integrate steel slag with soil and humus generated through the fermentation of wood chips. These units, carefully placed on the ocean floor, serve as an artificial conduit for the provision of iron, ultimately nurturing the marine ecosystem.<br><br>Remarkably, the results have been tangible and encouraging. Within a mere six months after the installation of these iron supply units, a flourishing bed of kelp emerged, flourishing some 30 meters from their inception point. The positive impact persisted, as confirmed through monitoring at two- and three-year intervals, in locations such as Mashike Town, Hokkaido, Shima-City of Mie Prefecture, Tanabe-City of Wakayama Prefecture and Himejima of Oita Prefecture.
