Welcome to the "New World"

Some days ago, I read an article about an ancient tribe that it appears in Brazil. They had been living alone, unaware of what it was happening out of their lands.
They hadn't clothes, they were undressed. But they wanted to go to look for help or to hunt. At the end they were discoverted and their images were showed to everybody through news and social networks.
I would like to put in their possition. They have  been living without all necesities that we have, no light, no internet, no money, no mobile phones ....... And I wonder who are happier? No doubt that they are happier than ours because they didn't need all things that we have and that if we hadn't we wouldn't be without them.
Never had I thought that in this world would be able to exist people like them. I hope they can live their life like before because now they have a new danger: their extition like a tribe and the lost of all their traditions.
I wish they could live their own life. But I only can say : Welcome to the new world.
