I think the most fascinating aspect of the internet is the information it produces. You can access information on different topics from the comfort of your own home, office or anywhere else. Think of a world without the internet. A world without the internet will loose a lot of it's people daily. The reason is because, imagine if there is a tsunami coming. Because there is no internet, many people will not know the weather forecast. The only people that will hear about the tsunami are those that work with satellite networks. So then, what will happen? A country can have it's people wiped out, and have only satellite network workers left. What if there are only two satellite network workers and they can't have kids. So that country will be wiped out because of the fact that they didn't have access to information. Hope i helped.
