I know the difference between mineral and bottled water. You don't usually get mineral water from the tap though. I just mentioned the transport for carbon emissions but it's actually also pumping it up from the source, producing bottles, cooling it, i.e. the whole production and distribution process.
And yeah, Draugnar, producing tap water also costs energy (duh!) but producing bottled water costs about 1,100 to 2,000 times as much energy. (http://environment.about.com/od/greenlivingdesign/a/bottled_water.htm). You're a huge idiot for thinking it's the other way around. It doesn't matter much whether it is in plastic or glass bottles either. Plastic bottles cost more energy to produce, glass ones cost more to transport, overall it's pretty much the same.
Anyway, it's great to see how easy it is to excite the anti-environment fools frequenting this forum. You're a bunch of predictable little puppets responding exactly as I had expected.
Oh, and krellin, my computer is powered by wind energy and other sustainable sources, mostly wind though. So, as always, you don't know what the fuck you're talking about.
