Why should I become a media literate?

I should become a media literate in order for me to know what are my limits and boundaries in using media and its different forms.  It helps me to be aware on what are the do's and don'ts in using the media for my personal purpose or sharing information to others. It gives me knowledge on how to behave when using the media or teach me the ethics on using the media. It can help me to understand the informations in the media and I can also share it to the other people who needs it the most. I can use it to teach other people on what are the proper way in using media or enlighten them with my knowledge about it.
