It's been said before, its been said better before, its been said an awful lot lately, but I have to say it again. Stop buying bottled water! It's wasteful and pointless.

An average bottle of water requires: many times more water than you actually get to drink to manufacture and distribute; requires fossil fuel input for the plastics, bottling and distribution; is a ridiculously expensive investment in a disposable resource; and is not even necessarily any safer to drink than US tap water.

In some countries where the tap water is not safe to drink, it may make more sense. But in the US, where the tap water is some of the cleanest and safest in the world to drink, bottled water is just ridiculous.

If you just can't stomach straight tap water, invest in one of these instead of disposable bottles of water.
