eutrophication
This term describes a specific ecological imbalance where an excess of nutrients, primarily nitrogen and phosphorus, triggers a runaway biological reaction. It carries a strong negative connotation in environmental science, as it signifies the degradation of a healthy aquatic ecosystem into a hypoxic or anoxic state.
Because it refers to a complex biochemical process rather than a discrete object, the word is treated as an uncountable mass noun. It does not take a plural form in standard scientific discourse, and speakers do not refer to multiple eutrophications; instead, they describe the degree or extent of the process.
