The Great Debate: Irrigation? Money? Written Language? Wheel?

Whether it was through Powerpoint, discussion, video, or digging for artifacts, we have learned about some "firsts" of Mesopotamia. We have discovered that Mesopotamia, the first Civilization of the world, was the first to invent written language(cuneiform), irrigation, the wheel, and money. Four things that directly affect us in 2008. I think we can all agree that those are four very important things, especially in today's world. However, let us take a few moments to think about which, exactly, of the four is the most important? Your first instincts may tell you it's money. Judging from this weeks poll, most of you think that. But do not be so quick to answer, think about the world without each of the four. What is it like? You may think money is most important. With money, you can buy a car. However, without the wheel, your car is not going anywhere. With money, you can buy food, but without irrigation, crops would not get sufficient water, therefore, we would not have food to eat. No written language? It would make things quite difficult. We would not be able to communicate with each other which means no talking on the phone, no emailing, no texting and the worst of all, no blogging.

Part 1: So, If you could only pick one of the four inventions for today's world, what would it be? Explain your answer with specific details.
Part 2: Look at somebody elses comment and respond to them. You will respond to another students' comment by posting a new comment.
