2. Violence becomes a regular and common on the media, and that makes seem almost ok
3. Body image becomes a problem because of the amazing, and photoshopped, bodies that the celebrities have, which can cause eating disorders and other problems

5. The media is distracting from school and can cause problems with grades and more
6. The media is all about material objects and commercial, and that can be a bad influence especially on young children
