Antarctica ,which today is a ice dessert used to be tropical ,fossilized tropical plants have been discovered under the ice ,

modern civilizaton is exchanging forrests for concrete and tar

as well as open space mon argriculture ,of which ,in the end a lot of land also becomes desserts (because of irresponsible agriculture usening fertilizers

,to many cattle and over grazing ,heavy machinery that compacts the earth and raises the salt ,

as well as over pumping deep carbon aquifiers and the shallow surfice ones. depleting the ground weater and when the irrigation stops
the desertification begins.

we are in danger of becoming a dessert planet ,like Arakis in the book Dune by Frank Herbert,

and like Mars
