I think we should stop drinking bottled water. There's no need to be drinking it if you're living in western communities. The other thing I would suggest - and I feel it particularly here in Australia, because we have very severe drought - is to be aware of how much you're actually consuming. Right now, it's very rainy, but that doesn't mean we can drink all the water we want. Conserving and constantly thinking, "how much do I really need?" should definitely be part of our vocabulary.
