From the back cover:

"The eco-community is the best version of the city. Ignoring this groundbreaking fact is like ignoring the destruction caused by widespread urbanization, which is one of the most serious phenomena of modern times and threatens to eradicate the city itself, as well as many other natural features of our planet.

Urbanization is not only a social and cultural event of immense historical significance; it is also a terrifying ecological event. In an era when the vast majority of residents in North America and Western Europe consider themselves urbanites, we are obliged, even solely for ecological reasons, to study modern urbanization.

We must investigate not only its impact on the natural environment, a subject that has been the focus of detailed research by many authors, but even more today, to examine the changes urbanization has brought about in the sensitivity of society."
