Hardly a new enemy, but whatever. The recycling problem has existed since the 80s (at least), and the problem of people using bottled water and thus exposing themselves to risks of bacterias and so on has been around for as long as I've been anti-bottled water. My reasons against are purely environmental and chronic tight-arsed in nature. Buy a Brita, for god's sake, people! Then you won't have to bother yourselves over where the water is really sourced from, whether it's fit for consumption, matches the quality of tap, whether there's enough fluoride, etc.
Buy a Brita. Please.
