The last ice age ended just 10,000 years ago. People were migrating around the world long before that. The fossil record seems to indicate that Homo sapiens were found first in Africa. Australia was inhabited by people 48,000–50,000 years ago. People had already found their way to North America between 16,000 and 25,000 years ago... some think even before that. South America seems to have been inhabited between 12,000 to 14,000 years ago.
It is interesting that even from times where forms of written communication already existed that there is still confusion about the history of populated areas. The Greeks began expanding their influence approximately 750 BC. Alexander the Great was born approximately 365 BC, Cleopatra was born approximately 69 BC, the Roman Empire existed between 31 BC – AD 476 and Genghis Khan was born approximately AD 1167.
How little will future generations remember about our civilization? We now appear to be in rapid decline by many historic measures. "Climate Change" is the least of our worries.
Yes, it is interesting that the world was so concerned about over population in the late 1960s-1970s. When the book The Population Bomb came out.
Now, we are seeing the collapse of countries because their birth rate is so low. Already happening in South Korea, Japan, Italy and China. Peter Zeihan has been preaching about it for several years as the main cause of the downfall of China.
The only difference between the US, Italy, Spain, GB and China is that people from other countries actually want to move to Spain, Italy, GB and the USA.
I have been trying to convince Mrs Woodbutcher for two years now about moving/retiring to Italy. Even places in Tuscany are becoming affordable. Southern Italy is cheap. Even places right on the coast of the Med/Adriatic are cheap in the southern part of the country.
