Urbanization & Sustainability : a possible merge ?

"La coulée Verte" in Paris

We are now living in the 21st  century. The city's era, at a time where the unique characterized latin word still understandable is megalopolis, and where a "Hub" doesn't mean your cousin but a big airport. A mix between sustainability and urbanization seems to be really impossible when we think about details. Urbanization is synonym of concrete jungle, metro,  traffic jams and horrible affluence everywhere at any time, of natural genocide and reduced green spaces. It's true that building and developing a city may be the most unsustainable thing to do but a certain "joint venture" is still possible.

Building "green lungs" between skyscrapers was one of the main goal of the previous New York mayor Michael Bloomberg with his high line project which has been a success. In paris "la coulée verte" welcomes every week thousands of tourists or local inhabitant coming to enjoy a special way of visiting paris thru a green mile.

Finally, in Mexico, city with the reputation of a high level of pollution el "Bosque de Chapultepec" helps the city and its inhabitants to breath somehow. The adaptability of cities can be relatively easy when it's well thought and well established.
