Environmental degradation is formally defined as an undesirable alteration in the physicochemical or biological characteristics of air, water, and soil resulting from excessive addition of materials or energy that poses harm to living systems. Within pollution science, this concept categorizes contaminants into distinct physical states (gaseous, liquid, solid) based on their origin sources and specific mechanisms such as atmospheric deposition, effluent discharge, and residue accumulation. The theoretical framework establishes causality between pollutant introduction—via industrial exhausts, agricultural runoff, or thermal energy release—and the consequent reduction of environmental carrying capacity across these three primary domains.
