A former Facebook executive has said social media is doing great harm to society  the world. The executive is a man called Chamath Palihapitiya. He joined Facebook  2007 and became a vice president. He was responsible  increasing the number  users Facebook had. Mr Palihapitiya said he feels very guilty  getting more people to use social networks. He said the networks are destroying society because they are changing people's behavior. Twenty years ago, people talked to each other face to face. Today, people message each other and do not talk. People also really care  what other people think  them. They post photos and wait to see how many people like the photo. They get very sad if people do not like the photo.
Mr Palihapitiya said people should take a long break  social media so they can experience real life. He wants people to value each other instead  valuing online "hearts, likes, and thumbs-". Palihapitiya also points  how fake news is affecting how we see the world. It is becoming easier  large websites to spread lies. It is also becoming easier to hurt other people online. Anyone can hide  a fake user name and post lies  other people. Palihapitiya said this was a global problem. He is worried  social media so much that he has banned his children  using it. However, he did state that Facebook was a good company. He said: " course, it's not all bad. Facebook overwhelmingly does good  the world."
