Agriculture is pretty labor-intensive, and it's not as simple as planting a seed in the spring and coming back in the fall to check on it. It takes a plan involving irrigation, especially in the birthplace of civilization, Iraq.

I've always thought that agriculture brought about the first harnessed source of energy--raiding your neighbor to capture slaves to work the fields.

And isn't it interesting that slavery ended when fossil fuels were discovered...

"especially in the birthplace of civilization, Iraq."

I don't believe that either. (The evidence for earlier civilizations are underwater.)

Guess again there is still a great deal of slavery in world. In the birth place of civilization and humanity no less. Slavery is rampant in North Africa and the Middle East.
