Public art existed all along, but ecological art just naturally grew out of my thinking and writings in that area for years. I didn't get involved in it; I started what then became a movement.

Every one of my works, when I'm looking back, becomes some kind of solution, or something to concentrate on. Something to pay attention to and maybe change direction.

I went through about six or seven painting methods just to see what I didn't want to do. And then I got off the wall, and went into the environment.

I study what I work with. I studied all these different fields of science that I needed for my work. I studied how to mine a landfill and what to plant in it. It's fascinating because you learn a new field each time.

What I did for my last act as a painter, if you call me a painter, was to photograph the weave of the canvas, and enlarge it and enlarge it until it became like a landscape.
