人类现在的生态环境正在日趋恶化,究其原因是我们赖以生存的地球正在发生变异。地球遍布臭氧洞地球的这种变异,一方面是人为因素造成的:例如随着人类物质文明水平的快速提高,大量的氟化学物质使臭氧层遭到破坏,导致极地上空出现臭氧洞,有害的紫外线直射地表,使极地周边国家的人患皮癌者日益增加。另一方面是来自地球本身,据资料表明现在的地磁场正在减弱,在过去的百年间地磁减少了大约5%。如果按这个比例继续减少,再过大约二千年,地磁场就会完
The current ecological environment of mankind is deteriorating due to the fact that the earth on which we live is being mutated. On the one hand, this variation in Earth's atmosphere over the ozone hole is caused by human factors. For example, with the rapidly increasing level of human material civilization, a large amount of fluorine chemical substances have destroyed the ozone layer, resulting in ozone holes over the polar regions, harmful direct ultraviolet radiation , So that people around the polar countries suffering from skin cancer are increasing. On the other hand, it comes from the Earth itself. According to the information, the present geomagnetic field is weakening. In the past hundred years, geomagnetism has been reduced by about 5%. If you continue to reduce by this ratio, about two thousand years later, the Earth's magnetic field will end
