China is building cities for a 20 to 40 percent increase in population. India is quickly growing. The carbon footprints of that and other development around the world are overwhelming.

Many people put a green button on their collar and feel good, just like a lot of people put an American flag on their lapels and feel patriotic. It's not enough.I'm not dismissing it.

Most of our cities built since the war are bland. They're modernist, they're cold, and now architects want to go back to that.

In an ideal world, pressure should come from below and from the top.

There is stuff I would have liked to have done. But there are no sour grapes.

I used to sketch - that's the way I thought out loud. Then they made a book of my sketches, and I got self-conscious, so now I don't do it much.

Anybody I talk to agrees that maybe 2 percent of the building environment since the war, we could call architecture.
