My point is, though, that even though the film photography industry has cleaned up a lot of its act, we still use a tremendous amount of resources to do our work, and I said so to bring some balance to the discussion. ALL photographers bear responsibility to think about the environmental impact their practice has.
Part two was about bringing forth some aspects of digital photography that is not often discussed - the power required to operate the camera and the computer is just one portion of the big picture. Servers in data centers consume enormous amounts of energy, and what happens to that hardware after it wears out? The waste problem is gigantic. The largest man made structure on Earth is the waste dump at Killdevil Hills in New York State. The Western worls (most of it) exports trash to other countries in Africa. These are problems of gigantic proportions. Once the toxic substances leak into the soil and the ground water, it will be near impossible to clean. Imagine what that will do for ALL life on Earth that depends on it! It is a time bomb waiting to go off.
