Pepsico and water

When Pepsico states that they give back more water than they consume, what does it mean?
The aquafina bottle states this was achieved by water harvesting and that the claim has been endorsed by an independent audit.
All this is part of the feeling most of us have that a particular amount of water is ours, a particular piece of land is ours...
Long back when I first read Chief Seattle's speech in Illustrated Weekly, I was moved. In those days, environment concerns had not arisen. We still believed the resources could be consumed for ever. Still, the power of the speech was moving.
I cannot remember the exact words, but the sense I got was that like the sky, land cannot be fenced and divided and owned.
Now, in the present context, it is more than just moving..........it is prophetic. We own water, we own land, we own the skies above our land and maritime boundaries mean we own the oceans and by doing so, we haven't done ourselves any good.
