Sustainable city must begin with sustainable development which is vital to our survival to meet the needs of the presentwithout the compromising the ability of future generations to meet their own needs. With the attitude of sufficiency and thefeatures of adequate consumption, we're connected to all things in our environment; we're not the center of it. In myopinion, initially, a sustainable city is that everyone take into account that the negatives of unbalanced economic growthhave on the enviroment and on people's well-being.
