Film, chemistry, paper etc... are consumables, and the need for them is directly proportional to the work you do. As is the effluent. The ecological costs are heavily tilted against traditional methods.
It's not terribly relevant in these circles. Most of the photographic waste in the world came from snapshooters, and most of the silver effluent came from institutional darkrooms (minilabs, schools, hospitals, dental offices, etc.). A few fogies with view cameras are a minor source of the polution, whether using silver or silicon.
