This leads to question the food capacity of the planet to the current global population, suggesting that this capacity has been exceeded, in the same way that exceeded the capacity of tolerance of carbon dioxide. The Metropolitan Museum of Art recognizes the significance of this. At the congress of eco-cities, emerged as the parameter that half a million inhabitants is the maximum size that could have a city to be sustainable. There was this figure who conditioned to a city where there were accommodating private cars, all these alternatives discounted in the disappearance of this type of vehicle, discussing, if it was gradual or drastic surgery. Also, to be discerned and the intensity of the issues discussed, there is a disjuncture between the eco-towns and eco-villages, arguing which the latter were more likely to sustainability. As shown, and this will increasingly perceiving through the contents of the media, advances are becoming reality.

The question, as reflected in almost all the forums where they discuss these issues, is the reluctance of the bulk of the populations included somehow in the alternative “American way of life” of Euro-American civilization, to even have any idea that there lifestyles that are unsustainable. Already Wilfredo Pareto in his “Soziologie Generale di Tratatto, 1917, identified as a basic human attitudes (waste) to” neophobia, “or fear of the new. In fact the new, not so much. What happens is that there are several precedents to previous generations, who believed with foundations based on their experiences that could cope with daily life in a way that begins to be rapidly unsustainable. Aligned within flows that cause a cultural change to address this problem must for our stock, as only intend to continue contributing to suggest that they begin to consider to be adopted different lifestyles of those who until now made it possible for large sections of the population, enjoy a relatively “high quality of life”, to be checking that has been ephemeral duration. Paradoxically, appear to be in a better capacity and ability to cope with future scenarios imaginable, those sectors of the population of the planet to some degree were being excluded, “high quality” ultimately enjoyed only minority.
