How importante is the internet in our life?

In my life i use the internet so much and like it, but this is really necessary?
Well, necessary is not because there are some people that unfortunately doesn't have this acess, but it is almost a rountine for some people, their lifes are based on it.
Although there are many people that really don't like how importante the internet have become in our lifes, it is a fact.
For me the internet is one of the best created things of the human and that habe to be used.
