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

I always run into these Ph.D.s. They write and write and write about sustainable development. Then these guys ask me, 'But, how do you do it?' They are scared to death to do anything.

There is no endeavor more noble than the attempt to achieve a collective dream.

Brazil will change when its cities change.

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

The city is not the problem; the city is the solution.

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.'
