Globalization or (globalisation) is the process by which the people of the world are unified into a single society and function together.

The film is humorous but illustrates a good point . We have mixed up the worlds people and the environments they evolved in, that made them what they are, are no longer in play.
This subject fascinates me. It has happened in what Carl Sagan would call 'a fraction of a second in the history of human existence', and its effect....hummm I would say its the biggest 'screw with mother nature' we've ever done and the effect has yet to come.
1491 this was a very different continent and the effect of 1492 was devastating to it.

Smallpox is now said to be the cause of the massive Buffalo herds of the Americas. ...scratching your head on that one are you.
The Buffalo population was controlled by it human Amerindian predators, smallpox was so devastating to the population the loss of predator caused the buffalo population to explode.Visiting Europeans having not seen America before this event mistakenly thought America was like this before they arrived, not realizing they where seeing an effect of Globalization.

Then how was the buffalo population controlled before the arrival of the amerindians?



I hope that someday we can put aside our fears and prejudices and just laugh at people.

I've read they have been her 13,000 years so what ate the Buffalo before that would be a mystery.

Smallpox did not exists in the native american population until introduced by Europeans.

Prior to 13,000 years ago I believe much of north America would have been covered by glaciers, so there wouldn't have been any humans or buffaloes.

Does anyone know how far south the glaciers went in the last ice age?

The modern buffalo descended from Bison latifrons, an enormous, shaggy, European herbivore that crossed the land bridge that once connected Asia and North America. The crossing took place between 200,000 and 800,000 years ago and not long thereafter the land bridge submerged and North American Bison latifrons was isolated from the old world forever.

The ancestor of the buffalo that we know was left to evolve on the North American continent during a time of climate warming. About 120,000 years ago that species died out and was replaced by two new forms. Bison antiquus was closely associated with early man in North America and became extinct about 10,000 years ago. But the second descendant of the first buffalo, Bison occidentalis survives to this day. Though still a huge herbivore, it is smaller than its predecessors and its horns angle back rather than protrude outward like the ancient buffalo's. As the years passed, Bison occidentalis learned to utilize the main ecosystems of North America and, in doing so, evolved into two distinct races: the plains buffalo, Bison bison and the mountain or wood buffalo, Bison athabascae. These two races still exist and make up what is now known as the North American buffalo or bison.

To answer your question Peter:

Did the Ice Age cover all of the earth with ice?
In: Snow and Ice, The Ice Age


Answer
No. The earth has experienced many glacial periods. The last one, about 10,000 years ago, is often referred to as the Ice Age. About 30% of the earth was covered by ice, most of it in the Northern Hemisphere. Many parts of Africa and South America, in contrast, were warm.
In North America, glaciers covered the ground as far south as Illinois and Missouri.

PS: Peter, just so you do not credit me with unwarrented intelligence there is a source of information available other than people on the message board called "google it"

Which explains why archaeological evidence of the earliest humans known on this continent were first discovered in Clovis, New Mexico (hence they are now referred to as the Clovis people) and other parts of the country in the south and southeast, where they were driven over the course of centuries by the advancing glaciers . . which also removed all traces of earlier settlements. BTW, buffalo migrated south as well.

And it is appropriate to attribute when you do that.
