Cyber bullying has become an important issue as students spend more time learning online. Cyber bullying occurs through social media, emails, chat rooms, text messages, and involves name calling, insults, and threats. Schools students and those with unsupervised internet access are most at risk. Cyber bullying can lead to low self-esteem, depression, poor school performance, and in some cases, suicide or violence. Schools are educating students on the issue and intervening in cases of cyber bullying. There are also efforts to pass legislation against cyber bullying, but laws are difficult to create and enforce.
