As we grow older, approaching the age to understand Destiny, we see many things turning from prosperity to poverty, feeling sentimental; after serious consideration, we think the phenomenon is related to the "cycling" and "balance" as advanced in Book of Changes. We wish to further explore whether there is a rule governing all the ups and downs. Mencius advocated that a successful king rises every five hundred years. As Chinese history shows, orderliness and disorderliness come alternatively. Then, why is the world in disorder? It must concern our survival. Thomas Robert Malthus in his work "An essay on the principle of population" noted that population increases geometrically. The earth and the countries we dwell in are limited space and we human beings are the one that really kills the environment. Hence, in the ancient times, one key to overcoming the population problems is natural disasters or man-made errors. But still now, we take the best way to conquer such a problem is again natural disasters or man-made errors. Nevertheless, nuclear weapons are so destructive that nobody dares to resort to it. That is also why there were only minor battles after the World War II. Then, what about natural disasters? We have been facing more and more disasters and, hopefully, the story of the movie "Day after tomorrow" will not happen to us! Book of Changes is a book that analyzes the true meaning of change, where some things change and some things do not change. The so-called "mean" as pursued by the Confucian school simply refers to "balance". To sum up, either science or human art proposes to strike a balance. For instance, in accounting, borrowing and lending must be balanced out. Another example is that we have to redress a balance among the four wheels of cars. At present, entities as big as the earth and as small as the surroundings around us all hang in balance. Nevertheless, a power in the universe will come to maintain a balance in everything, which is the wisdom of Chinese culture, that is, things are restored and renovated like a circle. In the process of development, technology has solved some problems while at the same time it has created some other crises. This is exactly what we have read in the western fable: people pushed the stone up and down the hill; they were doing the stupid thing over and over again. A piece of news from BCC reported that the images captured by the satellite might disclose a mystery regarding the disappearance of the Mayan civilization. These scientists used a satellite image and spotted five newly discovered Maya ruins, including hundreds of architectural monuments like temples in the Guatemala jungle. The satellite image and distance detection can break through the clouds and blocking fog, looking into the surface. Scientists think that satellite images may be able to provide answers to the mysterious disappearance of the Mayan civilization. Scientists judged that the Mayan civilization highly flourished leading to the explosion of population, which prompted the Maya to continue to exploit the forest land and cultivate agricultural development. However, the results of the unremitting forest destruction caused regional warming, decline in rainfall, and, ultimately, water depletion. Therefore, Mayas scattered into four winds, hence the collapse of the civilization. As there are so many problems the whole world faces now and they are all related to human beings, our traditional ideas such as frugality and desire suppression actually provide new food for thought. On the contrary, it is not the outward expansion of western countries to grab resources and colonies or the superstition as to the omnipotence of technology that counts. So, when all the rising countries in the globe are pursuing economic progress and growth, should we not seek to reach a balance in the cycling world?
