Final answer:
Social change refers to the alterations in society that result from collective behaviors, social movements, and factors like technology and the environment. It is manifested in actions like eating blueberries for health, driving electric cars, or voting for green politicians, driven by information and public opinion shaped by experts and social media.
Step-by-step explanation:
The examples given represent social change, which is the alteration in society caused by collective behavior and social movements, as well as external factors such as technological innovations and environmental shifts. Social change can encompass a variety of forms, including changes in eating habits to reduce health risks, adopting new technologies to mitigate environmental issues, and participating in political processes to support certain values and causes. This change often arises from the flow of information from experts to the general public, influencing public opinion and behaviors.
Social change is driven by numerous factors, and social media has become a powerful tool for facilitating the expression of opinions and organizing groups around causes such as environmental activism. As people change their sources of information, their opinions may also shift, leading to changes in consumer behavior, technology use, and voting patterns. It is also essential for democratic societies where public awareness and voter demands can direct political focus.
