@seif I've been asking myself the same question!

I think while internet and media have been extremely useful in propagating knowledge and information, the by-products of such easy and convenient channels of propagation are loads of useless information.

I would define useless information as those that do not add value to your life, those that are not just nonsensical spam but those that spread negativity and hate. 

The key, then, is not to avoid the internet and media. These channels are not the enemy - they're just tools in the hands of those who wield it. I believe we should just be discerning consumers/readers/browsers. It takes some amount of determination and discipline to process whatever you receive via an internal filter. 

On a practical level, it could be to unfollow those propagators of useless information and clean up your Facebook feed, for instance. Facebook is a great way to keep up with your friends, be involved in various communities etc, but you don't want useless information to be cluttering your feed (as well as your brain space). 

Hope this helps! (:
