Every MSM article about PO, and GW and all other stories on resource depletion for that matter, carry this single-generation focus without exception. Looking out for number one trumps posterity every time - it is natural & inevitable for the vast majority of individuals

If this would change, we would have a fighting chance at doing the right thing.  Why is it that posterity as you say, or the desire to leave an admired, lasting legacy is no longer a value that seems to be held by many, but importantly, is also no longer held by those with money and power ?  

You really only need look at the way our most lasting creations such as buildings have changed since the late 19th century.
