Bullying - Why and What can be done?

For my Senior Service Project in high school I spoke to over three-hundred eighth graders about tge realities of high school. I informed thwm that there were three reasons why bullies do what they do:  *below are the points I used my PowerPoint and the script *

1. To feel good - since they have nothing to feel good about within themselves and have found nothing to be proud of within their lives.
2. Power - Bullies they ether love the feeling of having power over others or because  they lack the power to change their bad circumstances at home.

3. Control: it's  not enough to have power over otha they must gave what they lavk most in their own lives.s

Now granted I was a eighteen year old, high school senior talking to a bunch of  eighth graders, so naturally I was quite confident in my information. Especially since it was based off of first-hand experience being a victim myself.  Now fast forward half -a-decade later and I know now that bullying doesn't just occur in school but also occurs in the workplace as well, even in retail by fellow coworkers. I also know that the real causes behind this phenomenon are extensive and circumstantial. But nothing makes this behavior morally right. So in  the course of my research I concluded that the reasons are only relevant to determining the appropriate solution to diffuse and decrease bullying. 

So what can be done?

As you probably know Bullying has evolved into cyberspace thanks to social media like Facebook and Twitter. According to my research there are some really great apps out there to help fight off cyberbullying. Yet one thing that doesn't exist (as far as I have researched) is an app that connects all social media accounts.
