7 principles for building better cities

In summary, Peter Calthorpe says that the architects have to start to think how to design cities for three billion of pepole by the year 2050, because, if we don't have actions to design new cities, the solutions proposed for adaptate to the climatic change will be futile. We have to change our form of life: we live in cities designes for cars, but the streets are not be able to cope many vehicles, least for us. Our houses are stored as if they where a honeycomb, but this isn't all: our neighbourhoods are separated for a lot of towers, roads, railways, rivers, subways, economic situations, educational situations, among other ways. We have to make cities great places. How? Reducing carbon emissions transporting by bikes, designing growing smart cities with mixed-use environments, interacting with our neighboors, incorporating more green areas into urbanistic plan, working in community, living in community (all of us with other living things, remember that all the livin things are the environment).

Bringing the situation to Santiago, most of the problems present by Calthorpe occur in chilean capital city. People are separated by economic situation: rich people live since Forest Park to east, and the rest of Santiago divided into two ways: majority of people that live within iron belt are middle class, and majority of people that live outside iron belt are low class. Neighborhoods and urban planning are changing in accordance with economic class. In Las Condes, urban plant is similar to medieval plant and blocks are sinuous, height of the building is more or less homogeneous, there are many green areas, the roads are wide and clean, and there's greater access to environmental education (healthy organic food, recycling centers, among other elements). Santiago center urban plant is more organized than Las Condes urban plant because blocks has been traced in checkerboard, but height of the building is very diverse, there's less green areas, the width of streets is diverse and waste begins to appear on the streets, there are many commercial space. Estación Central urban plant is very disorganized in compared with two previous communes and blocks are very diverse, height of the building is diverse since the construction of vertical ghettos, there's only one big green area and the rest are spaces abandoned and covered with waste, the width of streets is diverse and very dirty and there's much crime.

Finally, I'm partly agree with Peter Calthorpe because, while bicycles are a good solution to fight with carbon emissions, I'm not clear about what we do with obsolete cars: where we are going to save the cars or their pieces, what will happen with waste.
