Two comments were made earlier. One was about film being worse for tne environment. The other was that digital was more expensive overall.
Regarding film being worse for the environment it really depends what you shoot. If it's B/W then the stop bath, developer and fixer mixed and flushed down the drain is pretty much OK as it's chemically neutral. B/W chemicals aren't anywhere near as toxic as colour chemistry. Colour chemistry - labs can't just dump the chemicals. They send them off and specialist firms extract the silver and repreocess the chemicals. The waste from the user end is in thrown-away film, batterries and prints. Prints all contain PVC.
With digital the waste is hidden. Each time you upgrade a camera, the old camera will eventually get thrown in the trash. More digital cameras are produced and sold than film cameras ever were - each tiny upgrade much sought after and heavily advertised. Really - what's the huge difference between the 10D and the 30D? There isn't one - the 20D is a 10D with a few minor tweaks and the 30D has some even more minor tweaks. Basically you have 10D, 10D.1, 10D.11. Then lets look at batteries - if you use disposables then because digital uses a ton more power than film cameras you're using a ton more. If you're using rechargable, how much of that power comes from fossil-fuel power stations or from nuclear. How much comes from clean energy sources such as wind or sun?
Now let's look at the cost comparison.
Film costs about $7 per roll and processing is about the same. That's $14 per 36 exposures. You buy the camera and lenses once and don't generally bother with the daft upgrade bandwaggon. If you have a film camera that works you use it until it is unrepairable and then buy a new film camera.
With digital you buy a new camera every 2 years because advertisers tell you that your old camera is a piece of $%^& and that you should buy a new one. The fact that a 3mp camera can produce a very nice 10x8 eludes most people. The fact that a 400mhz computer running Windows 98 with poto processing software and which is not web connected (thus not needing antivirus or firewall or antispyware products) will run as well now as it did when it was new also eludes people.
You don't have to jump onto the upgrade bandwaggon with digital. SUre - the startup costs are high. The camera is more expensive. As regards printers and computers - how much did your darkroom cost to build, maintain and run?
Now - how many shots have you taken 2,500 digital? 10,000 digital? More? Now divide that by 36 and multiply by $14 and tell me that film per shot is cheaper than digital. You have to take the whole cost into account - not just little snippets.
