Natural landscape vs unnatural landscape

The botanical meetings are in Tucson Aridzona.  The natural landscape is quite lovely high desert; saguaro cacti abound.  The resort is nice but surrounded by unnatural landscape too, a golf course.  See if you can tell the difference in the image above.  What a remarkable waste of water, even if it is reclaimed waste water.  Such a simple landscape as a monoculture of grass takes a huge water and energy input to maintain.  The botanists have all taken walks through xero-scaped areas and they report them as lovely.  No one has said a thing about the golf course.  What is there to say?
