Recent trip to Germany. Interesting differences from Australia and NAmerica:
- Bottle of water 70 euro cents; deposit on plastic or glass bottle, 15-25 cents. Guess what: people don't throw out recyclables.
- No plastic grocery bags at all. None. BYO or learn to juggle.
- Bikes everywhere. Looks like a uni campus, everywhere.

I don't think non-disposable plastic water bottles are a problem, but there are better ways of doing things than throwing out packaging every time you take a drink or go to the shops.
