Is television good or bad?

In this generation, there are television sets almost everywhere.
However, did you ever think about why there are television sets all around?
 Even though the television is not absolutely necessary, why it is surronding us?
That's because of two powerful reasons.
 It distracts people and many people actually earn money by using it.
Therefore there are two main problems, too.
One is that it might cause poisonous addiction and another is that it makes people violent and unhealthy.
Now I'll explain about these.

Firstly, watching television makes people insane.
There are lots fo cases that support the idea of television does harm.
There are some cases that it damages people's brain and some cases show that it makes people not very creative and can't concentrate well.
Moreover there are a few countries that are banning to have televisions in the houses who have babies.
This means exactly the one thing-that television is not really necessary but harmful for people.

Secondly the television makes people violent and unhealthy.
It is scientifically proved that electromagnetic waves are affectable to people, especially for children.
The electromagnetic waves are coming out from the television so it's not good for your health to watch TV.
Moreover you';; become fat if you watch too much TV because you won't exercise.
Also it makes people violent because TV shows people lots of violence and it really affects people's thoughts.

In conclusion, the television is not necessary and affect us in bad ways.
Watching it makes us go mad and weaker.
Moreover it makes us violent, too.
Therefore the televison is not  very nice thing to be with.
