Catastrophe in the environmental context refers to a sudden, large-scale disaster or event that causes significant damage to ecosystems, human settlements, and Natural resources. These events can be natural, such as hurricanes, earthquakes, and floods, or human-induced, such as Oil spills, deforestation, and industrial accidents.

A cation in the environmental context refers to a positively charged ion, meaning an atom or molecule that has lost one or more Electrons, resulting in a net positive electrical charge. These positively charged particles are ubiquitous in natural systems, playing fundamental roles in soil chemistry, water quality, nutrient cycling, and the transport of pollutants. Their interaction with negatively charged surfaces, particularly in soil and water bodies, is a critical process known as cation exchange.
