A city grows like an organism. It is a structure of living and working together a mix of functions.

I have realized after all these years that a city that has a good quality of life attracts jobs. People don't want to invest in places if there is no quality of life.

Cities are not problems. They are solutions.

A lot of people assume that the expensive ideas are the most effective ones, but that is simply not true.

We have to change from 'ego-architecture' to 'eco-architecture.'

Curitiba is not a paradise. We have all the problems that most Latin American cities have. We have slums. We have the same difficulties, but the big difference is the respect given by people due to the quality of the services which are provided.

I always try to say, 'If you want to help the environment, try to do just two things. One, use less of your car. Second, separate your garbage.'
