My point is that digital photography is based on a business model which provides only a single source of profit. That is the endless sale of digital cameras with their negative impact on the environment. The impact is from their manufacture and the discarding of obsolete models.

The model for analog photography was based on a consumables market. Before digital cameras the main source of profit was from consumables film, papers and chemicals not from the sale of cameras. For the average person a single camera was used for years without any need to upgrade. The cash cow was the consumables which were bought routinely for these cameras not the cameras themselves. Modern films and papers contribute very little to harm the environment in terms of heavy metals and other pollutants. The same cannot be said concerning the manufacture of digital cameras.
