Water is a human right because it's a basic human need, but it must be vigilantly protected and not squandered. Water resources are not infinite, and they must be managed appropriately to ensure that clean water comes out of the faucet at an affordable rate. Failure to properly manage your water properly just ensures it will become significantly more expensive, more scarce, and more dirty.
Cleaning contaminated water is significantly more expensive than preventing it from being contaminated in the first place. This is why people are rightfully concerned about things like fracking and industrial waste. Here in Florida, we get concerned at the thought of our springs being contaminated. These channels run deep underground and are the source of many of our freshwater rivers.
I tell everyone that before you state your opinion about American President, you should know who your mayor is (if you have one), what type of government the city you live in is, and where your water comes from. If you don't know that, then you have no right to complain about the president, because those three things have far more impact on your life than the guy in the oval office does.
So long story short, water is a human right, but it must be protected, and it must be managed responsibly. Bottling water just makes it more expensive at the tap, or even makes it so there are no water resources altogether. In places like Las Vegas and Los Angeles, people are going to start feeling the effects of what it's like when there's no water, and it's going to be a harsh lesson because the effect of having no water sets in very, very quickly.
Is that what people want? Take your water seriously. You can't go more than a day without it.
