Abstract
The environment and ecosystem of coastal waters depend on materials and life supplies from the land basin. Therefore, forest devastation is directly linked to ocean desertification, so integrated management of both is important. In this paper, we focused on versatile substances, i.e. “humic substances”, which can stably transport substances into the sea and have high plant-physiological activity, and provide explanations based on examples of research conducted to date. It is important to discuss the “sustainability” and “diversity” of seawater science in a multidisciplinary and systematic way by consolidating resources, energy, and the environment into a single reaction equation. In the case of research on the environment and biological resources, we propose adding “humic substances”, which provide a more versatile reaction field to this multifaceted reaction equation.
