Pervasiveness refers to the quality of being widespread or existing everywhere. It describes how certain ideas, behaviors, or technologies can infiltrate various aspects of life, influencing many people and environments. For example, the internet has become pervasive in modern society, affecting communication, education, and commerce. In a more specific context, the term can apply to pollution, which is pervasive in many urban areas, impacting air and water quality. Understanding pervasiveness helps identify issues that require collective action, as widespread problems often need comprehensive solutions to address their root causes effectively.
