Is Access To Water a Right?

Some folks want to have the access to clean water legally defined as a right. Is it a right?

If so, then shouldn't access to food be a right also? Is access to food a part of the right to life? My understanding has always been that those who want food need to work for it. Earn money to pay for it or plant and care for it or gather it yourself. Many people die of starvation everyday, yet no one is saying that access to food is a right. (Many people seem to think that health care should be a "right" too. So ... you should have the right to see a doctor for free, who will tell you that you are starving, but you would have no "right" to have access to food? But I digress.)

Is this wish to legislate access to clean water as a right merely a response to the fact that people die faster without water than they do without food? Or is water so essential and access to it so limited that access to it must be legislated to keep society working? Or is this just the latest in a long line of fear-mongering, control-of-the-populace scare tactics?
