Water body self-pollution refers to the contamination of water bodies caused by human activities. Synonyms for this term include self-inflicted water contamination, self-induced water pollution, and accidental water pollution. Self-pollution occurs when pollutants from human activities such as agricultural practices, industrial activities, and domestic wastes find their way into water sources and contaminate them. This leads to a decrease in the quality of water, making it unfit for consumption and also leading to adverse effects on aquatic life and the environment. It is, therefore, crucial for individuals and organizations to take responsibility for their activities and prevent water body self-pollution. Other synonyms include self-contained water pollution and self-generated water pollution.
