Nitrogen metabolism is a multifaceted and interconnected web of biochemical processes that sustains life on Earth. From the synthesis of essential biomolecules to the regulation of ecosystem dynamics, nitrogen metabolism influences a myriad of biological phenomena. (Garcia, S. 2023. Nitrogen Metabolism and Ecosystem Sustainability. Biochem Pharmacol (Los Angel). 12:339.)

Weather refers to atmospheric conditions at a particular time in a particular location, including temperature, humidity, precipitation, cloudiness, wind, and visibility. Weather conditions do not happen in isolation, they have a ripple effect. The weather in one region will eventually affect the weather hundreds or thousands of kilometers away. (UNDP. 2023. The Climate Dictionary. https://www.undp.org/publications/climate-dictionary)

In fisheries, parental stocks are the adults of a biological stock that are able to reproduce. (SDG 14.4.1 online course – Fish stocks sustainability. https://elearning.fao.org/course/view.php?id=502)

Principle adopted by the UN Conference on Environment and Development (1992) that in order to protect the environment, a precautionary approach should be widely applied, meaning that where there are threats of serious or irreversible damage to the environment, lack of full scientific certainty should not be used as a reason for postponing cost-effective measures to prevent environmental degradation.
