Then the whole bunch can worship Tammus together and have a big old pagan holiday, which many in Europe commonly observe, and the “Holy Virgin” Proserpine and the god of hell Pluto.
I guess you missed the part of the plan to dam the Congo River and reverse it dumping water from the equatorial African tropical jungle runoff into three giant lakes in what is now the Sahara desert. This alone would reverse the desertification of the Sahara which only began less than 6000 years ago with the climate zone shifts of the melting of the last period of glaciation. Look at the link I posted its fascinating. Humans have this mega engineering tech we lack the cohesiveness as a species to use it due to political idiocy. Not all communalism is of the devil sometimes we as a species need to do things.
I would expect it would have a huge effect on the land ecosystems all around the Mediterranean.
