Interesting thread and I wonder just what courses we have to follow to ensure the continuance of analog photography regardless of what ensues.
On another note, I thought that I had read remarks at the time of the newly emerging digital past concerning how the manufacturing process for digital were much more endangering to the environment then the processes for film production. I use to work for electronics firms and some of the chemicals used for production were highly toxic and environmentally dangerous. If your at least 45 and above you may remember at one time or another where companies were caught quite often dumping behind their buildings. Of course what could be worse to the human environment then nerve gas and other agents being stored in caverns in leaking drums or massive amounts of carbon dioxide in the air because of corporate greed.
