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.'

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

We can’t have landfills forever and we can’t ask others to accept our trash.

Many cities end up putting off things because they want to understand everything. They don't understand that innovating is about starting. Taking care of a city is a process that you start, and then give the population space to respond.

After working in cities for nearly 40 years, I am telling you that every city can improve its quality of life in less than three years, no matter the scale or the financial conditions.

A city is like a family portrait - you don't tear it up if you don't like your uncle's nose.
