Everybody can reach you in a mobile phone. Communication technologies are contributing to increase mobility and at the same time allowing stabylity. Internet allow you to work at home, everywhere any time. And you are always available in your mobile phone. To move or to stay still? I can work in Paris while being in Cali, there is no boundary border fence. I am thinking in attachment to homeland, a place, decide to settle. I am thinking in moving or staying still. Mobility and stability in the contemporary city. Always thinking in life and environment, how mobility and stability in the city affects waste production, pollution, carbon emissions, detrietment of human and no human life.
