I use completly mechanical cameras to last me a long time and take special care with water waste, so I don't print FB.
Furthermore, the enlarger wastes a lot less energy than my computer workstation.
If you are careful with chemical disposal and water waste (which it seems our privileged brothers and sisters care little about), you are set.
Now if you could get the enlarger running with solar power...
Real photographs, created in camera, 100% organic,
