In the past few years, there has been a growing concern about the impact of social media on young people. Many experts argue that excessive use of social media can lead to negative consequences, such as mental health issues, reduced face-to-face communication skills, and a decline in academic performance. However, some studies suggest that social media can also have positive effects, such as providing a platform for self-expression and fostering a sense of community.
