Slate is much more commonly found in wet areas, especially around rivers in the United States, so it wouldn't be very available to Natives who were more inland.
Humans must unlearn their greediness in order to live in harmony with all the other animals and creatures. When we do everything in order to better ourselves and not the people around us, we are forgetting our basic human instinct. Humans view the world as their to own, rule, and ruin. This is not the case, as the world is owned equally by every animal.
I hope this helps! :)
Depends on when you are talking about. This sounds like a Biblical Question so I'll answer it that way.
Very surprisingly, during David's time the population wasn't much more than a couple of thousand according to archaeologists. The area covered was no more than 40 acres even during Solomon's time when Jerusalem was a very important city. It may have had a larger population than in David's time, but the size was not much different.
Forty acres was not much. To give you an idea just how big that might be, consider that a section of land is 1 square mile. 1 section = 640 acres.
40 acres is 1/16 of a square mile. That's like 5 city blocks in any direction and that might be overestimating in. Imagine that? I was very surprised to read that. The temple was massive when you read about it and so were the stables for the horses.
Anyway, if I find out any differently, I'll post in comments. These are secular accounts and not Biblical ones, but I don't hear anyone seriously disputing this.
The ancient Greeks lived on a rocky and mountainous peninsula. Fertile land/soil was scarce in the mountainous regions but mild climate allowed for some farming. People lived in isolated communities. Mountains made travel by land difficult and dangerous so people mostly traveled by sea. Greek culture was spread easily due to several islands surrounding the peninsula and sea travel.
One advantage of being an unskilled worker in Egypt is becoming a slave. Being a slave would have been an easier task than building the pyramids.
