Drinkwater in plastic bottles - why?

One cannot but notice that a large number of people are buying water in plastic bottles. Quite often the bottles are not recycled, but end up in the huge pile of plastic waste, which is currently contaminating especially our seas. It is estimated that hundreds of thousands of fish and marine birds die currently as a result of ingesting plastic waste.

But back to water in plastic bottles. Did you know that approximately three liters of water are used to produce a litre of bottled water? Did you know that occasionally the source of the water in bought bottles is tap water in the production place of bottled water? Further, I cannot see the reason why small water bottles are transported, e.g., from France to USA.

It is probably true that fresh water will be an inadequate environmental resource in the world in future. Consequently, we should save it where we can. One of the easiest ways of doing this is to drink tap water whenever possible, and when it is not, use local bottled water in recyclable bottles - and actually recycle the bottles, not throw them away.
