What factors were most important to establishing and maintaining a civilization?

But the development of writing greatly enhances civilization. This pair of images from space shows a portion of the southern Empty Quarter of the Arabian Peninsula in the country of Oman. Once you realize, through climate change, the need to find lower-impact energy sources, the less impact you will leave. This area has been identified as having "inspired some of the most important developments in human history including the invention of the wheel , the development of cuneiform script, mathematics , astronomy and agriculture. The Medieval Warm Period was driven by an increase in solar radiation, while the Little Ice Age was caused at least in part by a decrease. Studies of the early Holocene provide clues to what was such a world like. For Hodder, there is only one explanation.
