The answer is Disease.
While disease can have significant impacts on societies, it is not typically considered a primary driver of social change in the same way that social institutions, the environment, and technology are. Diseases can lead to temporary disruptions and may accelerate certain changes, but they are not a consistent or widely contributing factor in the broader context of social change.
Social institutions, such as family, education, religion, and government, play a crucial role in shaping societal norms, values, and structures. They are fundamental in driving social change by influencing behavior, policy, and cultural evolution.
The environment is a significant factor in social change, as it affects resource availability, living conditions, and can lead to shifts in population and economic activities. Environmental changes can prompt societies to adapt in various ways, leading to social transformation.
Technology is a major driver of social change, as it transforms how people communicate, work, and interact. Technological advancements can lead to shifts in economic structures, social relationships, and cultural practices, making it a widely recognized factor in social change.
