Whatever the cause we are approaching a point where our kids kids will be in a hell of a mess. Now whether that is down to humankind or a natural cycle is up for debate but probably the best thing to hope for is humankind because there is a chance that we can do something about that. If it is a natural cycle then stick your head between your legs and kiss your arse goodbye 'cos we ain't stopping that.
Thing about it though is we are delaying and sidestepping things that should be done and leaving it all for the kids to suffer.
