I was also going to illustrate that the same thing occurs with water... we pollute it, then clean it again, add things to it, and then it is good for consumption, selling it in bottles... NOT!
Which begs the question; is access to fresh clean water a right? Or, will that be patented and sold for ever more exorbitant prices too?
In the Movie Last of His Tribe, Ishi (Graham Greene), when offered water on his death bed says that he wants "sweet water", white man water tastes bad... his friend, Professor Alfred Kroeber, (Jon Voight) agrees that white man water tastes bad.
I liked this series of videos posted a while back by O Julien...
