Like the video show, I think that the language is one of the things that makes us human, because the language bring us the possibility of conserve in the collective memory all the things that the humanity was discovered, the language help at the  maintenance and of course the change of the culture, and because of this we can transformed our reality, doesn’t matter if I am saying something real or not, the point is that if I say the possibility exist, so the world and the humanity can change with a simple sentence. 

Now like Pagel say the language joins us, but divide us too in the case of the language of the people was different, creating the idea of superior and inferior languages. However I don’t think that the solution is make a universal language, because like I say in the first paragraph the language is culture so the different languages are different culture and more diversity, the language makes that us conserve our differences and our singularities despite of the constant process of globalization that we live.   

In my personal experience I speak Spanish and I love it because a big part of the world can understand me, I feel part of something, I feel part of Latin-American, and feel that I can move and travel without difficulty for big part of my continent, but in the same time I feel different and apart of the north American, Canadian or the Asians and this permit me conserve my individuality or my identity like a Chilean person or like a Spanish-speaker.
