Photography is a strong tool, a propaganda device, and a weapon for the defense of the environment...and therefore for the fostering of a healthy human race and even very likely for its survival.

Much is missed if we have eyes only for the bright colors. Nature should be viewed without distinction... She makes no choice herself; everything that happens has equal significance. Nothing can be dispensed with. This is a common mistake that many people make: They think that half of nature can be destroyed - the uncomfortable half - while still retaining the acceptable and the pleasing side.

Photographs are believed more than words; thus they can be used persuasively to show people who have never taken the trouble to look what is there.

My emotions, instincts, and interests are all with nature.

I do not photograph for ulterior purposes. I photograph for the thing itself - for the photograph - without consideration of how it may be used.

The more you photograph, the more you realize what can and what can't be photographed. You just have to keep doing it.

Every photograph that is made whether by one who considers himself a professional, or by the tourist who points his snapshot camera and pushes a button, is a response to the exterior world, to something perceived outside himself by the person who operates the camera.
