地球的神秘线(英语)

Along a special line of latitude, known as the 30th parallel north, lie numerous sites of ancient civilizations and impressive natural features. Ancient civilizations appeared on the parallel, including Babylon, with its famous tower; Egypt, with its pyramids; China, with its Sanxingdui culture, etc. These civilizations appeared at a similar time, and all developed advanced bronze-making techniques. Were they part of a single super-line, as some think? It's argued that the 30th parallel north is a line of great natural energy, with frequent earthquakes and volcanic eruptions. This creates amazing natural features, including Mount Qomolangma, the Dead Sea, and rivers, such as the Nile, the Mississippi and the Yangtze. Lacking conrete evidence, some even claim it was a supernatural powers. Scientists, however, dispute these theories. It's more likely, they argue, that civilizations arose on the 30th parallel north because the climate there is generally warm and wet. Major tectonic plates meet at this latitude, causing earthquakes, which helped form the Himalayas. The rest, they say, is either coincidence or fantasy.
