It's pre-photography, a fossilization of time, Americans have done the Zen garden to death. I wanted to do something different.

I have a strong feeling about this quick movement and changing of society and populations growing - something scary.

I'm thinking about the end of civilization. We may not keep growing like we are now. There must be an end of civilization. That's what I did as a show at the Palais de Tokyo, the 33 scenarios of how this civilization ends.

I feel that I'm in a very interesting position, where I'm standing back to look at this change, at this moment in history of human beings. If the end of the civilization comes before the end of my life, that's lucky! I want to witness how this big story of humans ends.

Photography is like a found object. A photographer never makes an actual subject; they just steal the image from the world... Photography is a system of saving memories. It's a time machine, in a way, to preserve the memory, to preserve time.

All over the planet, nature is being transformed into 'un-nature' at breakneck speed...My life is part of natural history. I long to know where that history came from and where it is going.

I have no policy for my collection. For example, there's a bunch of meteorite [on the windowsill in my studio]. I touch it and I feel the energy from the universe. I have a 1/1,000th of a fragment of stone-age tools and pottery and debris. I can learn many things from my collection. Actually, the 1,000 Buddha, I wanted to buy it, but it's a National Treasure, so I couldn't. If you cannot buy it, just photograph it!
