The environment we live in is no longer connected to 
the mix of planetary processes which brought us all into being.
It is solely the product of human mental processes.
It is real, but only in the way that a theatrical play
or a fun house is real.
Our artificial environment is there and we can experience it,
yet it has been created on purpose by other humans.
It is an interpretation of reality,
it no longer reveals how nature works and 
it cannot provide much useful information to human beings 
who seek to see their own lives as part of some wider natural process.
We are left with no frame of reference untouched by human interpretation.
