Final answer:
According to Touraine's theory, there are more social movements in the modern world because they are seen as effective ways to reshape society, especially when conventional political systems fail to represent public views.
Step-by-step explanation:
According to Alain Touraine's theory of social movements, the reason there are more social movements in the modern world is because individuals and groups believe that social movements are an effective way to reshape society. Touraine's perspective on new social movement theory suggests that contemporary movements are not just responses to economic or political issues but also involve cultural and identity concerns, within the context of postindustrial societies. Social movements are organized collective efforts that aim to bring about change. Motivated by various catalysts, including technological innovations and environmental shifts, they offer an alternative means of political expression and influence, especially when formal mechanisms of democracy are perceived to fail in representing public views.
