The Chinese river dolphin has disappeared before our eyes within only two generations. Will we change course before other branches on the tree of life die off? It would be foolish to assume that we can somehow maintain our prosperity and our very future without the rich biodiversity on Planet Earth.
If you accept that water is the most valuable commodity on earth, then there is no financial argument against its production at whatever cost. Hopefully the world, regardless of national aspiration, political ideology, and systems of governance, will come to that conclusion in time to assuage our thirst for survival.
