Well, as a former history grad student majoring in late Republican Rome (yes, I have been many things, but rarely bored) it's hard for people today to realize that Africa Province (roughly, modern-day Libya) was the breadbasket of Rome. Along with, of course, that modern representation of Eden, Sicily. One should also study the contemporary records of the great fertility of once richly-forested areas of Spain that are now arid. It's easy - kill off the native vegitation, over-graze and/or exhaust the soil with poor farming practices, thus altering the index of reflection and heat circulation over large areas, which changes precititation patterns, which...you get it, eh? Man-made climate change is a firmly established fact.
As a species, we are somewhere between a parasite and a disease. If it was not for the presence of charming and intelligent folks like ourselves that convinces the Mother that humankind can occasionally be worth the hassle, I'm sure we'd be long gone. Despite the best efforts of the rest of the race to egg Her on to get out the Cosmic Neosporin and rub some on us.
So, how's your day? (*G*)
