China’s was the second pristine civilization to rise, and although the and separated China from the Fertile Crescent and India, there was cultural and technological diffusion. At times, China was ahead of Fertile Crescent civilizations in technological and cultural innovation. By eight kya, agriculture was firmly established in China. China has had less investigation of its prehistory, but it seems clear that China’s deforestation began with agriculture, just like everyplace else, and by 1000 BCE, China was largely deforested. The East Asian food complex is markedly different from the Fertile Crescent's, largely because East Asia relied on summer monsoons for its water, and winter rains provided water for the Fertile Crescent and westward, although civilizations were primarily based on seed and root crops. The rice paddy is the most sophisticated preindustrial agricultural system ever created. It by 3000 BCE, and rice paddies bred malaria to the extent that the paddy system in southern China was not successful until the local populace had partially adapted to malaria. Deforested lands alternately , and managing water in China became the foundation of imperial practice like nowhere else in history. Although , in practice they did nothing at all. Chinese emperors and the states they controlled, however, owed their legitimacy in their subjects’ eyes to how well they controlled flooding and drainage. The Yellow and Yangtze rivers carried more than 30 times the silt that the Nile did, and deforestation with the resulting flooding, siltation, and desertification have been major Chinese problems for thousands of years. Although it has been challenged, the idea that China reached early political unity due to few geographic barriers has merit. China has been politically unified almost continually for more than two millennia. The Han Chinese that dominate China are like white Americans, Canadians, or Australians, in that they invaded, conquered, and came to dominate lands initially settled by others.

When I arrived at my office, I turned on my lights and computer. When I was eating, I put the food that I brought to work in a refrigerator under my desk. During my work day, I interacted with many people in my air-conditioned, high-technology office environment. My cellular telephone was never far away. The view from my office window of the was pleasant. My computer interfaced with our distant data centers and the world at large via the Internet. When my workday was finished, I rode the bus home. In the winter, the furnace is programmed to stop functioning when my wife and I leave for work, and comes on soon before we arrive home, so we never experienced a cold house. In the evening, we might watch a movie on a DVD on our wide-screen plasma TV. When I am not fasting, I usually eat dinner, with the food in my refrigerator usually purchased at a that has an enormous produce section, with food grown locally and imported from as far away as New Zealand, China, and Israel. We have a high-tech kitchen, with a “smart” stove, refrigerator, and other appliances.

When I resumed my career in 2003, I became an early riser and consequently went to bed by 9:00 PM on most nights, and often read fantasy literature before I turned out the lights and snuggled into bed (with two comforters in the winter to keep us warm as we sleep).
