Digital photography and Photoshop have made it very easy for people to take pictures. It's a medium that allows a lot of mediocre stuff to get through.

I think the environmental movement has failed in that it's used the stick too much; it's used the apocalyptic tone too much; it hasn't sold the positive aspects of being environmentally concerned and trying to pull us out.

Somebody referred to what I do as subliminal activism, which I like.

I wish my artwork could persuade millions of people to join a global conversation about sustainability.

I can go into the wilderness and not see anyone for days and experience a kind of space that hasn't changed for tens of thousands of years. Having that experience was necessary to my perception of how photography can look at the changes humanity has brought about in the landscape. My work does become a kind of lament.

Sometimes you don't know why you're doing something. You're intuitively following, to see where it leads.
