Your effort is appreciated, but I have a couple of counterpoints to offer. First, the entire world does not meet the basic definition of “empire”. Inter active and codependent as the nations of the world are, they are not ruled by a single monarch or oligarchy or state.
Without unnecessary nit picking a number of questionable comments, I respond to your characterization of the Sahara Desert as being a desert due to abuse by people. Not so. This great desert is a natural, cyclical event due to shifting earth rotation every 26,000 years or so.
Increasing climate change may alter this regular cyclical event, but your attribution of its current condition as desert due to human activity is far off base.
Your central point has merit. Our world wide abuse of our planet has us headed for a great fall, and must be corrected NOW.
Trump, in his chosen ignorance, may in four years put the world in an irretrievable collapse.
Yes, it will be quite a show.
