Human civilisation 'will collapse' unless greed culture is stopped,

So let me get this straight.  Unless the "greed culture" which is the major theme of the current Human civilisation, is stopped, Human civilisation 'will collapse'?  What??  So let it collapse along with the "greed culture".  Done.  Problem solved.  Pay me.

In the end, might makes right. Nothing has changed since the caveman.
