You can't divorce civilization from nature - we totally depend on it.

I personally spend the majority of my time by far on outreach and education and fundraising and administration.

I've got at least two major project ideas that I've been chewing on for several years in my head and I've been trying to resist them both. But I have learned over the years that when they don't go away and they're still in there, you probably have to resign yourself to the fact that you're going to do something about them.

There is a glacier in Iceland, Solheimar, which has retreated a great deal, and every time I go back there and see what's not there any more, it does something to the heart. It makes you realise it's possible for a gigantic natural element to just disappear.

You can't divorce civilization from nature - we totally depend on it.

The problem is almost everybody is just recording the world with home photographic toys, not doing metaphor or ideas. We have a photographic culture that's not conditioned to think in terms of symbol.

The cumulative effect of each person making a change in his or her own life will make a difference.
